A cross-platform HTTP Client for RubyMotion that's quick and easy to use.
Supported platforms:
- iOS, macOS, tvOS, watchOS
- Android
It makes use of the officially supported networking libraries provided by Apple and Google. The goal of this gem is to provide you with a stable alternative to using these libraries directly, using a syntax that is much easier to use.
Please report any bugs and suggestions for improvement!
Add this line to your application's Gemfile:
gem 'motion-http'
And then execute:
$ bundle
$ rake gradle:install # Android only
If you will be making insecure requests (not using HTTPS), you will need to explicitly allow insecure HTTP requests by adding this line to your app's configuration (in your Rakefile
). You might want to do this if you are trying to access localhost in development.
app.development do
app.info_plist['NSAppTransportSecurity'] = { 'NSAllowsArbitraryLoads' => true }
end
Using motion-http
is quick and easy. You can use the simple approach for making one-off requests, or the advanced approach of creating a reusable API client for further customization.
The basic syntax for a request looks like this:
HTTP.method(url, options) do |response|
# this will be called asynchronously
end
Where method
can be either get
, post
, put
, patch
, delete
, head
, options
, or trace
.
For example, to make a simple GET
request:
HTTP.get("http://www.example.com") do |response|
if response.success?
puts "Success!"
else
puts "Oops! Something went wrong."
end
end
If you need to specify query params:
HTTP.get("http://www.example.com/search", params: { term: "my search term" }) do |response|
# ...
end
The response object contains the status code, headers, body, and shortcut methods for checking the response status:
HTTP.get("http://example.com") do |response|
puts response.status_code.to_s
puts response.headers.inspect
puts response.body
response.success? # 2xx status
response.redirect? # 3xx status
response.client_error? # 4xx status
response.server_error? # 5xx status
end
If the response body has a JSON content type it will automatically be parsed when requesting the response.object
:
HTTP.get("http://api.example.com/people.json") do |response|
if response.success?
response.object["people"].each do |person|
puts "name: #{person["name"]}"
end
else
puts "Error: #{response.object["errors"]}"
end
end
Use the follow_redirects
option to specify whether or not to follow redirects. It defaults to true:
HTTP.get("http://example.com/redirect", follow_redirects: false) do |response|
# ...
end
When making a POST
request, specify the :form
option and it will automatically be encoded as application/x-www-form-urlencoded
request body:
HTTP.post("http://www.example.com/login", form: { user: 'andrew', pass: 'secret'}) do |response|
if response.success?
puts "Authenticated!"
elsif response.client_error?
puts "Bad username or password"
else
puts "Oops! Something went wrong."
end
end
Likewise, to send a JSON encoded request body, use the :json
option:
HTTP.post("http://www.example.com/widgets", json: { widget: { name: "Foobar" } }) do |response|
if response.success?
puts "Widget created!"
elsif response.status_code == 422
puts "Oops, you did something wrong: #{response.object["error_message"]}"
else
puts "Oops! Something went wrong."
end
end
Request specific headers can also be specified with the :headers
option (overriding any previously set headers):
HTTP.post("http://www.example.com/widgets",
headers: { 'Content-Type' => 'application/vnd.api+json' },
json: { widget: { name: "Foobar" } }
) do |response|
# ...
end
All other HTTP method requests work the same way:
HTTP.put(url, params) { ... }
HTTP.patch(url, params) { ... }
HTTP.delete(url, params) { ... }
HTTP.head(url, params) { ... }
HTTP.options(url, params) { ... }
HTTP.trace(url, params) { ... }
A common use case is to create a reusable HTTP client that uses a common base URL or request headers.
client = HTTP::Client.new("http://api.example.com")
# Set or replace a single header:
client.header "X-API-TOKEN", "abc123xyz"
client.header["X-API-TOKEN"] = "abc123xyz"
# To set or replace multiple headers:
client.headers "X-API-TOKEN" => "abc123xyz",
"Accept" => "application/json"
# Note that it is valid for some headers to appear multiple times (Accept, Vary, etc).
# To append multiple headers of the same key:
client.add_header "Accept", "application/json"
client.headers.add "Accept", "application/json"
Then you can make your requests relative to the base URL that you specified when creating your client.
client.get("/people") do |response|
# ...
end
To make Basic Auth requests, either set the credentials before the request, or set it on your client:
HTTP.basic_auth('username', 'password').get('https://example.com/protected')
# or
client.basic_auth('username', 'password')
client.get('/protected')
The auth
method is another shortcut for setting any value of the Authorization header:
HTTP.auth("Token token=#{my_token}")
# or
client.auth("Token token=#{my_token}")
# same as
client.headers['Authorization'] = "Token token=#{my_token}"
By default, requests and responses will be logged. If you would like to disable this:
HTTP.logger.disable!
