rpcxio / rpcx-gateway Goto Github PK

比如认证 auth的key是__AUTH，写法是 k1=v1&k2=v2等

'X-RPCX-Meta': [
            "__AUTH=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2MTA0MzI3MTYsImlzcyI6ImhqeC1zZXJ2aWNlcyJ9.0d6qHC0Q1DJr_H58tiHkH0a6wpM4fH8mfBdFI-A1zYY"
]

add charset=utf-8 in response header

我下载后直接go build 出现以下错误，有一些方法没有定义？请问是我用错了吗？能指导一下吗？

This repo is a http gateway, I want to know is there any recommended WebSocket/TCP gateway?

I have a client which connect to server with WebSocket. And on the server side, I want to spilt the complicated logic into several service with RPC. So I need an WebSocket gateway.

请求同一个rpcx服务，第一下好的，第二下就会报错，一直循环
报错信息：
failed to dial server: dial tcp: address /rpc/xxxx: missing port in address

采用 etcd v3，单etcd节点，
后端rpcx服务提示：client has closed this connection

Current rpcx supports peer2peer, multiplepeers, zookeeper, etcd, consul, mdns registries. Gateway needs to add a common tool to support those registries

运行 cmd/gateway.go 后报错如下：
./gateway.go:56:10: undefined: client.NewZookeeperDiscoveryTemplate
./gateway.go:58:10: undefined: client.NewEtcdDiscoveryTemplate
./gateway.go:60:10: undefined: client.NewConsulDiscoveryTemplate

geteway和agent只有客户端例子，服务端怎么写呢？我看server里面写的和一般的服务端没什么区别，服务端监听的是8872，但是http请求的是9981端口，这样也可以？

怎样启动geteway，能有个教程就好了，对于新手有点懵，后面看见了cmd下面的代码才知道怎么回事儿了

cmd/gateway.go registry参数在不同注册方式上怎么写，能给一个例子吗？目前只看见一个peer2peer

var (
addr = flag.String("addr", ":9981", "http server address")
st = flag.String("st", "http1", "server type: http1 or h2c")
//registry = flag.String("registry", "peer2peer://127.0.0.1:8972", "registry address")
registry = flag.String("registry", "consul://localhost:8500", "registry address")
--------- i use consul ------
......
case "consul": //regAddr is localhost:8500
return client.NewConsulDiscovery(*basePath, "placeholder", []string{regAddr}, nil), nil

compli error:

2018/01/06 12:20:06 consul_discovery.go:59: INFO : cannot get services of from registry: rpcx/placeholder%!(EXTRA *errors.errorString=Key not found in store)
panic: Key not found in store

rpcx-gateway是无状态应用，所以可以轻松做到扩展。但如果是有状态服务的请求，rpcx-gateway是如何支持的，还是目前未支持有状态服务请求？

我用C实现了RPCX协议的简单通信，希望gateway能提供基于TCP的代理模式

rpcx-gateway只能通过代码方式发送http请求？不能像grpc-gateway一样使用curl的方式发送请求？

类似grpc-gateway，在定义method时指定http路径，请求时不需要通过header设置service/method，直接请求对应的URL path即可。这样感觉更方便些

rpc Echo(StringMessage) returns (StringMessage) {
  option (google.api.http) = {
    post: "/v1/example/echo"
    body: "*"
  };
}

Run go get -tags "xxx" github.com/rpcx-ecosystem/rpcx-gateway/cmd, and The following error appears
NewZookeeperDiscoveryTemplate is not found

依赖
github.com/rpcxio/rpcx-etcd v0.0.0-20201229103411-8317fc934fbb
而rpcx-etcd 这个版本需要go.etcd.io/[email protected]版本，
然后使用了goproxy.io代理后查看etcd所有版本go list -m -json -versions go.etcd.io/etcd@latest，缺少3.4.14版本。

请问一下，如果用这个网关，是把http 请求转成什么协议(tcp, quic ...)与rpc server 进行通信呢？

followed in gateway.go

g.mu.Lock()
if g.xclients[servicePath] == nil {
	g.xclients[servicePath] = client.NewXClient(servicePath, g.FailMode, g.SelectMode, g.serviceDiscovery.Clone(servicePath), g.Option)
}
xc = g.xclients[servicePath]
g.mu.Unlock()

cannot run g.mu.Unlock() if rpcx-service is not registed in consul, because call panic in consul_disconvery.go
you could add defer before g.mu.Unlock() .

gateway也没有办法将json转换为messsagePack编码，json的number没法准确的对应messagePack的Integer和Float
