Generic C/C++ client for Nakama server.

Nakama C/C++ Client SDK

C/C++ client for Nakama server.

Nakama is an open-source server designed to power modern games and apps. Features include user accounts, chat, social, matchmaker, realtime multiplayer, and much more.

This client implements the full API and socket options with the server. It's written in C and C++11 with minimal dependencies to support Unreal, Cocos2d-x, Oculus, and other custom engines and frameworks.

We also support various game consoles. Please reach out to [email protected] to discuss console support for your project.

If you experience any issues with the client, open an issue.

Full documentation is online - https://heroiclabs.com/docs

Usage

Client

The client object has many methods to execute various features in the server or open realtime socket connections with the server.

Use the connection credentials to build a client object.

NClientParameters parameters;
parameters.serverKey = "defaultkey";
parameters.host = "127.0.0.1";
parameters.port = DEFAULT_PORT;
NClientPtr client = createDefaultClient(parameters);

The createDefaultClient will create HTTP/1.1 client to use REST API.

Tick

The tick method pumps requests queue and executes callbacks in your thread. You must call it periodically (recommended every 50ms) in your thread.

client->tick();
if (rtClient)
    rtClient->tick();

Without this the default client and realtime client will not work, and you will not receive responses from the server.

Authenticate

There's a variety of ways to authenticate with the server. Authentication can create a user if they don't already exist with those credentials. It's also easy to authenticate with a social profile from Google Play Games, Facebook, Game Center, etc.

string email = "[email protected]";
string password = "batsignal";

auto successCallback = [](NSessionPtr session)
{
    std::cout << "session token: " << session->getAuthToken() << std::endl;
};

auto errorCallback = [](const NError& error)
{
};

client->authenticateEmail(email, password, "", false, {}, successCallback, errorCallback);

Sessions

When authenticated the server responds with an auth token (JWT) which contains useful properties and gets deserialized into a NSession object.

std::cout << session->getAuthToken() << std::endl; // raw JWT token
std::cout << session->getUserId() << std::endl;
std::cout << session->getUsername() << std::endl;
std::cout << "Session has expired: " << session->isExpired() << std::endl;
std::cout << "Session expires at: " << session->getExpireTime() << std::endl;

It is recommended to store the auth token from the session and check at startup if it has expired. If the token has expired you must reauthenticate. The expiry time of the token can be changed as a setting in the server.

string authtoken = "restored from somewhere";
NSessionPtr session = restoreSession(authtoken);
if (session->isExpired()) {
    std::cout << "Session has expired. Must reauthenticate!" << std::endl;
}

Requests

The client includes lots of builtin APIs for various features of the game server. These can be accessed with the async methods. It can also call custom logic as RPC functions on the server. These can also be executed with a socket object.

All requests are sent with a session object which authorizes the client.

auto successCallback = [](const NAccount& account)
{
    std::cout << "user id : " << account.user.id << std::endl;
    std::cout << "username: " << account.user.username << std::endl;
    std::cout << "wallet  : " << account.wallet << std::endl;
};

client->getAccount(session, successCallback, errorCallback);

Realtime client

The client can create one or more realtime clients with the server. Each realtime client can have it's own events listener registered for responses received from the server.

bool createStatus = true; // if the socket should show the user as online to others.
// define realtime client in your class as NRtClientPtr rtClient;
rtClient = client->createRtClient();
// define listener in your class as NRtDefaultClientListener listener;
listener.setConnectCallback([]()
{
    std::cout << "Socket connected" << std::endl;
});
rtClient->setListener(&listener);
rtClient->connect(session, createStatus);

Don't forget to call tick method. See Tick section for details.

Logging

Initializing Logger

Client logging is off by default.

To enable logs output to console with debug logging level:

NLogger::initWithConsoleSink(NLogLevel::Debug);

To enable logs output to custom sink with debug logging level:

NLogger::init(sink, NLogLevel::Debug);

Using Logger

To log string with debug logging level:

NLOG_DEBUG("debug log");

formatted log:

NLOG(NLogLevel::Info, "This is string: %s", "yup I'm string");
NLOG(NLogLevel::Info, "This is int: %d", 5);

Changing logging level boundary:

NLogger::setLevel(NLogLevel::Debug);

NLogger behaviour depending on logging level boundary:

• Debug writes all logs.

• Info writes logs with Info, Warn, Error and Fatal logging level.

• Warn writes logs with Warn, Error and Fatal logging level.

• Error writes logs with Error and Fatal logging level.

• Fatal writes only logs with Fatal logging level.

Note: to use logging macros you have to define NLOGS_ENABLED.

Websockets transport

Nakama C++ client has built-in support for WebSocket. This is available on all supported platforms.

Client will default to use the Websocket transport provided by C++ REST SDK.

You can use a custom Websocket transport by implementing the NRtTransportInterface:

rtClient = client->createRtClient(websockets_transport);

Activity timeout

Built-in websocket transport supports "Activity timeout" feature - if no any message received from server during "Activity timeout" then connection will be closed. Set 0 to disable this feature (default value).

rtClient->getTransport()->setActivityTimeout(20000); // 20 sec

You can change ping period on server - ping_period_ms parameter:

https://heroiclabs.com/docs/install-configuration/#socket

Android

To use our native C++ library in your Android application, you will need to include an additional .aar file that we ship for SSL support.

For example, in Gradle:

implementation files("<path/to/libnakama-sdk.aar>")

Then you will need to load our native library from Java by calling System.loadLibrary("nakama-sdk") when your activity is created.

How to build

Prerequisite

You should download vcpkg (https://github.com/microsoft/vcpkg) somewhere on your machine set your $VCPKG_ROOT environment variable to point to the repository.

Windows

• CMake >= 3.22
• Ninja
• Build Tools for Visual Studio 2022

Linux

• CMake
• Ninja
• gcc-c++/clang++

Ubuntu 18.04

Fresh Ubuntu 18.04 setup:

sudo apt update
sudo apt install git pkg-config g++ curl zip unzip tar make
mkdir -p ~/opt; curl -L https://github.com/Kitware/CMake/releases/download/v3.23.1/cmake-3.23.1-linux-x86_64.tar.gz  | tar -C ~/opt -xzf -
mkdir -p ~/bin; ln -s ~/opt/cmake-3.23.1-linux-x86_64/bin/cmake ~/bin/
cd /tmp; curl -L -O https://github.com/ninja-build/ninja/releases/download/v1.10.2/ninja-linux.zip; unzip ninja-linux.zip; mv ninja ~/bin
exec /bin/bash -l   # make ~/bin available on PATH
git clone /mnt/z/repos/nakama-cpp ~/localrepos/nakama-cpp
cd ~/localrepos/nakama-cpp
${VCPKG_ROOT}/bootstrap-vcpkg.sh

If you plan to use WITH_LIBCXX, then also do following:

sudo add-apt-repository --yes ppa:ubuntu-toolchain-r/test
sudo apt install g++-11 python3-distutils
export CC=/usr/bin/gcc-11
export CXX=/usr/bin/g++-11

OS X

• brew install ninja cmake pkg-config
• XCode or XCode command line tools

Build

There are preconfigured presets in the CMakePresets.json. You can get list of presets for your system with:

cmake --list-presets

Then configure the build system.

cmake --preset linux-amd64

The configuration step builds all necessary dependencies and installs them under ./build/*/vcpkg_installed.

Next, build the SDK:

cmake --build build/linux-amd64 --config MinSizeRel --target install

Linux

To build Linux release you can use provided Docker image like following:

docker buildx build -f scripts/Dockerfile --progress=plain --output=./out .

Android

To build for Android set your ANDROID_NDK_HOME environment variable to your NDK before building.

Your NDK is typically located within your SDK:<sdk>/ndk/<ndk-version>

Our prebuilt libraries target Android NDK 25.1.8937393.

Windows 32-Bit

We support native 32-bit builds. Keep in mind that when building from source, you must run your command in a 32-bit (e.g., C:\Windows\System32\cmd.exe) environment.

Build modifiers

Presets mostly represent platforms SDK can be built for. Sometimes within platforms build configuration need to be modified, but if we create preset for each build configuration we'd have too many of them. We have a way to alter build behaviour of any preset with a build modifiers mechanism.

Supported build modifiers are:

• LIBHTTPCLIENT_FORCE_WEBSOCKETPP: On Windows platforms libhttpclient always includes websocketpp transport and uses it if Windows doesn't support websocket natively (< Windows 8). You can set this build modifier to force use of websocketpp transport, so that it can be tested without installing Windows 7. If you
• WITH_LIBCXX: dynamically link with libc++ instead of libstdc++ on Linux platform.
  • LIBCXX_STATIC: link libc++ statically
• ADDRESS_SANITIZER: instrument library with AddressSanitizer

Build modifiers are CMake variables passed at configure time using -D switch. Example use:

cmake --preset linux-amd64 -DWITH_LIBCXX=ON

Release

cmake --install --preset linux-amd64 --config MinSizeRel

You should see dynamic library and headers in the ./out directory. This is your release.

It is safe to combine (overlay) multiple platforms releases in the same directory structure, because binary artifacts paths won't clash and include files are identical on all platforms.

MacOSX Universal binary

Currently, our dependency manager can't build non-CMake based projects as universal binary. Watch this PR for a proper fix. Until then building universal binaries requires building shared libs for arm64 and x86_64 architectures and gluing them together with lipo tool.

To build universal binary first compile individual shared lib for arm64 and x86_64. Following commands are for M1, adjust preset names if you are on Intel CPU:

cmake --preset macosx-x64-host_arm64
cmake --build build/macosx-x64-host_arm64 --config MinSizeRel --target install

cmake --preset macosx-arm64-host_arm64
cmake --build build/macosx-arm64-host_arm64 --config MinSizeRel --target install

cp -r out/macosx-x64 out/macosx-universal
lipo -create -output out/macosx-universal/nakama-sdk.framework/Versions/A/nakama-sdk out/macosx-{arm64,x64}/nakama-sdk.framework/nakama-sdk

You can then archive and release out/osx-universal directory.

Transports

Platforms vary in their implementation of transports for HTTP and WS. One of the transports, libhttpclient itself can use different implementations depending on the platform.

HTTP:

Platform	Transport
Windows	libhttpclient -> winhttp
Android	libcurl
Linux	libhttpclient->curl
MacOS	libhttpclient -> OS
iOS	libhttpclient -> OS
Windows 7	libhttpclient -> websocketpp

Websockets:

Platform	Transport
Windows	libhttpclient -> winhttp
Android	wslay
Linux	wslay
MacOS	wslay
iOS	wslay
Windows 7	libhttpclient -> websocketpp

How to integrate the SDK

There are three ways of integrating the SDK into your build.

Github Release

We provide headers and binaries for all supported platforms in our releases section.

CMake

After downloading it to a folder you've configured CMake to look for targets in, you can import our package via the find_package command in CMake: find_package(nakama-sdk).

vcpkg

Our SDK integrates with vcpkg by providing itself and a few dependencies through a git registry. To include it in your vcpkg manifest, create a vcpkg-configuration.json in your root directory.

{
    "registries":
    [
        {
            "kind": "git",
            "repository": "https://github.com/heroiclabs/nakama-vcpkg-registry",
            "baseline": "<commit>",
            "reference": "<branch>",
            "packages": ["nakama-sdk", "wslay"]
        }
    ]
}

Then you can add it as you would any other vcpkg port in your vcpkg.json:

    "dependencies": [
      {
        "name": "nakama-sdk"
        "features": [<desired-feature-1>, <desired-feature-2>]
      }]

vcpkg does not currently allow us to provide default features per platform, so you must specify your desired transports/features in your own vcpkg.json.

For an example, look at how our cocos-2d-x client does this. Also see our our built-in transports for each platform that we represent with vcpkg features. If you do not specify a transport for the platform, the client will expect you to pass in your own at runtime.

nakama-cpp's Issues

Add more client and realtime tests

• Add tests for matchmaking.
• Add tests for server-authoritative multiplayer.
  • You'll need to use the existing Lua modules to send a RPC request to create matches.
• Add test for creating and submitting tournaments.
  • You'll need to use this Lua module to create tournaments.

Add Subscriptions Functions

Ability to Get / List subscription purchases (as documented here) is missing.

Add Session Logout Function

This feature (as documented here) is missing.

XCODE gives "Linker Command Failed with Exit Code 1" on 2.5.1 and 2.4.0

This may be something I'm doing wrong, but I've followed the instructions in the readme to the best of my knowledge and I am unable to make it work.

I am aware there was an issue with 2.5.0, but I cannot build with 2.5.1 or 2.4.0 either.

The instructions say:

1. Add NAKAMA_CPP_SDK/include in Build Settings > Header Search Paths
2. Add libs folder in Build Settings > Library Search Paths:
   NAKAMA_CPP_SDK/libs/mac - for Mac

3. In General > Frameworks, Libraries, and Embedded Content add following:
   all .a files located in libs folder
   foundation and security frameworks

I get "Linker Command Failed with Exit Code 1"

Thank you in advance for any assistance.

Here is my program, in case that helps:

C++ CLient SSL verification problem

Greeting Developers:

When I use the nakama-cpp-2.5.1 to set a client with SSL, I encountered the problem :
"[Nakama::RestClient::reqError] NError: ConnectionError
message: [NHttpClientCppRest::request] exception: Error in SSL handshake
start error , error message:message: [NHttpClientCppRest::request] exception: Error in SSL handshake"

I just set the parameter.ssl to true. And the nakama server opened the ssl feature also.

And I have checked the source code of the nakama-cpp-2.5.1, I didn't find any place where could import the certificate.

I was wondering if there is any way to implement ssl communication to the server using nakama-cpp-2.5.1.

Thanks!!

Nakama cpp not compile xCode 12

Hi,
When I try to compile Nakama C++ SDK in xCode 12 using a Simulator (example: iPhone X), it doesn't work.
Using a real device it works perfectly. The problem is in simulators with different architectures.

Anyone can help me?

Error:

ld: in /nakama_cocos2d_sdk/libs/ios/libnakama-cpp.a(BaseClient.cpp.o), building for iOS Simulator, but linking in object file built for iOS, file ‘/nakama_cocos2d_sdk/libs/ios/libnakama-cpp.a’ for architecture arm64

Call RPC without a session

Hello,

I would like to have the ability to call RPC from client without the need to authenticate first.

Apple - Allow headers to be found solely via framework linkage

We think that due to a bug in CMake's PUBLIC HEADER property, users need to include headers via manually adjusting their header paths even though they've already specified that they need to link to the framework.

A modulemap file may be related.

Confirm iOS frameworks can be uploaded to app store without modification of info.plist

May need a version string or other data in the info.plist file for users to upload the framework to the appstore.

Support Android NDK r14b, for Unreal Engine

Currently as of the latest version, Unreal Engine 4.21 uses Android NDK r14b for Android, it is an old NDK which is not support with Nakama.

I know we've talked about this, just wanted to know if there's any updates on release time.

request: add library to Conan center

Please, consider adding library to the https://conan.io/center/

Client and Realtime Client different host/ssl config

Hi,
Currently, if we need to use a different host and/or SSL value for the client and the realtime client, the only way is to create a client as usual, and then a second one to be able to call the createRtClient(...) method, as this:

DefaultClientParameters parameters;

parameters.serverKey = nk_serverKey;
parameters.host      = nk_host;
parameters.port      = nk_port;
parameters.ssl       = nk_ssl;

_client = createDefaultClient(parameters);

... 
DefaultClientParameters parameters;
parameters.host = nk_rt_host;
parameters.ssl  = nk_rt_ssl;

NClientPtr clientForRt = createDefaultClient(parameters);
_rtClient = clientForRt->createRtClient(nk_rt_port, transport);
// we should have done _client->createRtClient(nk_rt_port, transport) if it was on the same host/same ssl config for both;

Maybe there should be a way to create the realtime client with the parameters we want :)

Custom query matchMaker

There's a problem when I try to find opponents using a custom query. When I use query = "*" it works. But if I try to use a custom query, for example query = "+test:test" it doesn't work anymore. Could we check it?

Topic in forums: https://forum.heroiclabs.com/t/custom-query-matchmaker/917

Malformed `Content-Type` header breaks with Nakama 2.7.x +

I'm experiencing an issue with the nakama-cpp lib talking to nakama in a docker container. It is sending a Content-Type: text/plain; charset=utf-8, application/json header (which is not valid AFAIK). I get back an golang mime type error.

I suspect this has always been an issue but only errors with 2.7 / golang 1.3.x (have not confirmed this). One annoyance is that the error never hit the nakama logs so for a while I was suspecting docker networking barfing on it before forwarding to the container. It was only after I realized that gRPC code 3 was being returned that I knew it was reaching Nakama but not error logging.

With nakama 2.5.1 container (does not error)

$ curl -X POST "http://127.0.0.1:7350/v2/account/authenticate/custom?create=true&username=" -H "Content-Type: text/plain; charset=utf-8, application/json" -H "Authorization: Basic <redacted>" -H "Accept: application/json" -d "{\"id\":\"<redacted>\"}"; echo
{"created":true,"token":"<redacted>"}

With nakama 2.7.0 container (does error)

$ curl -X POST "http://127.0.0.1:7350/v2/account/authenticate/custom?create=true&username=" -H "Content-Type: text/plain; charset=utf-8, application/json" -H "Authorization: Basic <redacted>" -H "Accept: application/json" -d "{\"id\":\"<redacted>\"}"; echo
{"error":"mime: invalid media parameter","code":3,"message":"mime: invalid media parameter"}

I suspect the issue is with cpprestsdk you use not being very smart/careful about which headers are actually allowed to have multiple of (as a comma separated list of values: https://github.com/heroiclabs/nakama-cpp/blob/master/third_party/cpprestsdk/Release/include/cpprest/http_headers.h#L172-L191 )
Since request.set_body() is called with no second content-type property https://github.com/heroiclabs/nakama-cpp/blob/v2.1.0/src/NHttpClientCppRest.cpp#L89-L95 the default of text/plain; charset=utf-8 is being used: https://github.com/heroiclabs/nakama-cpp/blob/master/third_party/cpprestsdk/Release/include/cpprest/http_msg.h#L677-L704 However, you are then adding more headers, including a Content-Type: application/json one https://github.com/heroiclabs/nakama-cpp/blob/v2.1.0/src/NHttpClientCppRest.cpp#L94 that was set earlier: https://github.com/heroiclabs/nakama-cpp/blob/v2.1.0/src/RestClient.cpp#L159

Do you have plan to support Windows ARM64 ?

The Hololens 2 use Windows ARM64.

[NRtClient::onTransportMessage] NRtError: BAD_INPUT

##Description

Error thrown by CPP client

##Steps to Reproduce

Create a Nakama CPP client on xcode

then add to matchmaker

auto successCallback = [](const NMatchmakerTicket& ticket)
 {
   std::cout << "Matchmaker ticket: " << ticket.ticket << std::endl;
 };

 //int32_t minCount = 2;
// int32_t maxCount = 4;
 //string query = "*";
 //NStringMap stringProperties;
// NStringDoubleMap numericProperties;
 //stringProperties.emplace("region", "africa");
 //numericProperties.emplace("rank", 8.0);
std::cout << "minCount: " << minCount << std::endl;

 _rtClient->addMatchmaker(
     minCount,
     maxCount,
     query,

C++ - Return a future from functions

Using the functions that run on another thread e.g. client->authenticateDevice() don't return any way to control their execution, please can you return a future from these functions so i can await them?

Here's an example of a workaround i'm using at the moment:

Error cancelling matchmaking from the same session ID using Nakama CPP client

Description

Using nakama C wrapper in nakama's CPP client produces an error when trying to cancel matchmaking using the same session. Debugger output when running local nakama suggests that the matchmaking handler expects the Party ID or Session ID to be present, exclusively -- not both at the same time.

What's the expected flow here? Are we using wrong session to initiate/cancel the matchmaking?

Steps to Reproduce

Using C NakamaWrapper

RTClient->addMatchmakerParty(
		TCHAR_TO_UTF8(*PartyID), TCHAR_TO_UTF8(*matchQuery), minmatchedCount, maxMatchedCount, stringProperties, {}, SuccessCallback, ErrorCallback);
...
RTClient->removeMatchmakerParty(TCHAR_TO_UTF8(*TicketId), SuccessCallback, ErrorCallback);

This is the same client using the weak pointer to the NRtClientInterface

Compile with position independent code enabled

Hi,

First of all, thanks for making this library!
I've been writing a Godot GDNative wrapper for Nakama https://github.com/opcon/nakama-godot, which compiles into a shared library.

To do this, the nakama-cpp libraries need to be compiled with position independent code (-fPIC). I've made this change locally, and everything is working.

Is it possible to compile the released versions of nakama-cpp with -fPIC?

I don't know enough about C++ to know if this has performance/other implications.

Cheers :)

Feature: Add possibility to add parameters to RPC request

From within UE4 I call an rpc function like this:

		auto successFunc = [](const Nakama::NRpc& rpc)
		{
			UE_LOG_ONLINE_SESSION(Log, TEXT("Session Create Success"));
		};
		Nakama::ErrorCallback errorFunc = [](const Nakama::NError& error) 
		{
			UE_LOG_ONLINE_SESSION(Error, TEXT("Session Create Error: %s"), UTF8_TO_TCHAR(error.message.c_str()));
		};

		std::string foo = R"({"owning_user_id": "Test","owning_username":"TestName","session_name": "GameSession","session_state": 0})";
		client->rpc(sessionPtr, "sessions/create", foo, successFunc, errorFunc);

In some cases there might be the need to add url parameters or headers to an RPC request. However this is currently not possible.

For example a user might have an RPC that updates data of a player-party. Showing the intent by using PUT could make api intent clearer. Another example would be a server whose response to a procedure can be a different MIME type and the client passes the type via header.

Add build and release instructions.

• We need more build instructions for Windows / Mac / Linux (both 32bit and 64bit).
• We also need to bundle the release as GitHub releases as the file sizes are massive.

It build always failed.Can I use vcpkg install nakama to build .dll and .lib?

vs2019 build .dll always failed.
I use vcpkg build cpprestsdk.

Now what should I do?

Add Create Match with Name

This feature (as documented here) is missing.

Add Huawei Purchase Validation

Purchase validation for Huawei (as documented here) is missing.

Callback from authentication request results in undefined behavior if Nakama client has been destroyed:

After a call to authenticateDevice(), if the endpoint being connected to is slow (in my case, firewalled due to a security group configuration "bug"), and the NClient object is disconnect()ed and destroyed, I am still seeing what looks like a callback from within nakama-cpp.dll (I'm using the Unreal client, but have looked through the code enough to suspect the bug is here) will still fire. I cannot figure out how to cancel this outstanding auth request in a clean way, and I do not see code in this repo that does so either.

Thanks in advance for your time.

Add Sign In With Apple method

In nakama-cpp library, these are the methods that we can use in order to authenticate a player to Nakama Server:

virtual void authenticateDevice(.....)
virtual void authenticateEmail(.....)
virtual void authenticateFacebook(.....)
virtual void authenticateGoogle(.....)
virtual void authenticateGameCenter(.....)
virtual void authenticateCustom(.....)
virtual void authenticateSteam(.....)

These methods works perfect, but we CAN'T authenticate through Apple.
If we use a third-party login service, Apple is forcing developers to implement Sign in with Apple (GameCenter is not enough).

Nakama Server is already supporting it: https://github.com/heroiclabs/nakama/releases/v2.13.0
But we need to add this feature to nakama-cpp library.

Topic related: https://forum.heroiclabs.com/t/sign-in-with-apple/1057

Thanks

Add Google Purchase and Subscription Validation

Purchase and Subscription validation for Google (as documented here) is missing.

Crash in ppltasks Library

Background:
Compiled the Nakama c++ client library, including CppRestSDK, gRPC, SSL, RapidJson, and zlib, for use in ARM64 on the Hololens 2. Using C++/WinRT but not using the /ZW switch so it's still conformal C++17. Everything compiles correctly and the program runs properly on the Hololens when deployed. (This isn't the emulator version, it's the actual ARM64 hardware.)

I copy/pasted the default example class from nakama-cmake-client-example.cpp into our code, as a way to bootstrap the development. Dropped the class into our App class, and the default initializer starts as expected. Inside _client->authenticateDevice, the software hits an exception inside ppltasks at line 1910 when the "_LockHolder" mutex goes out of scope and UNLOCKS the mutex. It does sucessfully lock it. Also, from what I can tell, this is also NOT the first time through this code in the program, because when I put a breakpoint on it, it doesn't crash the first time through.

The callstack looks as such:

.exe!std::_Mutex_base::unlock() Line 67
.exe!std::lock_guard<std::mutex>::~lock_guard<std::mutex>() Line 444

.exe!winrt::App::Scene::{ctor}::__l2::<lambda>() Line 380

Let me know if you need more information, I would love to resolve this.

Side note: When I run it using the gRPC client, I get no crash but it's not seeing my Nakama server, so that's why I'm using createDefaultClient instead of createGRPCClient.

Nakama::opt::optional performs unexpected conversions when compiling with different C++ language standards

With further investigation, I can confirm it is due to misaligned language standards. By changing my project from C++latest to C++14 Nakama::opt::make_optional aligns with the nonstd::optional_lite::optional class.

This is unfortunate that the nakama-cpp headers changes types depending on the language version. I think a potential fix would be to provide the two optional class interfaces in parallel (introducing a std::optional when available) or to just commit to a more hardened Nakama::NOptional type that could potentially allow conversions with nonstd::optional_lite::optional or std::optional.

Support SSL / WSS.

We need to support SSL for both gRPC as well as Websocket connections (WSS). This should be added as an option similar to the Trace option.

2.5.0 release does not have libs for iOS/OSX/Android

Can't find precompile libs for iOS/OSX/Android. Could you please fix it?

Is there a way to generate C++ Client API Reference docs?

Similar to something like Java Client reference docs:
https://heroiclabs.github.io/nakama-java/current/

This should be generated using a tool (something similar to Doxygen, but may be better?) and published as GitHub pages in the /docs folder of the master branch.

Headers missing from v1.60 release?

Greetings,

I downloaded v2.6.0 release for win-x64 and was looking forward to adding it to my Cmake project.

'find_package(nakama-sdk)' worked happily enough, but I wasn't able to find header files anywhere in the release folder.

The readme says "We provide headers and binaries for all supported platforms in our releases section." but I am not finding the headers anywhere. Please let me know if I'm missing something. Thank you!

This work needs to be submitted against the nakama-docs repository so we can publish it directly on the website.

[2021.12.14-19.24.25:604][968]LogExit: Executing StaticShutdownAfterError

The same code causing this issue on Linux works as intended on Windows.

Input payload differences between Rest and RT clients

We've noted that:
The Rest client:

void RestClient::rpc( NSessionPtr session, const std::string & id, const opt::optional<std::string>& payload, std::function<void(const NRpc&)> successCallback, ErrorCallback errorCallback)

works with a regular JSON encoded string for payload
where the RT Client:

void NRtClient::rpc(const std::string & id, const opt::optional<std::string>& payload, std::function<void(const NRpc&)> successCallback, RtErrorCallback errorCallback)

Will not work unless you JSON encode the JSON encoded string (as second time).

This has caused some head scratching a few times since the Nakama server will return an error (which does not end up in the error log) if you provide a JSON encoded string (only encoded once).

It would be really nice if those two rpc functions acted the same (they have the same signature) and the RT one did the extra encoding/escaping internally as needed.

Thoughts?

Move library to C instead of C++

Problem:
Having the library written directly in C++ is good, when the client uses stdlib themselves. Yet as soon as the client uses their own version of certain types (e.g. UE4s smart pointers) interfacing with each other becomes much harder and often involves converting the type from C++ to C and then the clients version of the type. Another solution would be to forego the client types altogether and stick with stdlib, which sometimes isn't possible

Solution:
Move the C++ implementation to C. Since C is the least common denominator in most cases many libraries would benefit from a singular codebase (e.g. UE4, Android, Swift users). In addition clients, who implement their own versions of certain C++ std types, more often than not accept plain C types as arguments.
