em-http-request
em-http-request is a Ruby gem for making asynchronous HTTP requests using EventMachine. It allows you to perform multiple requests simultaneously and handle the responses as they come in, rather than waiting for each request to complete before making the next one.
In short it supports: - Asynchronous HTTP API for single & parallel request execution - Keep-Alive and HTTP pipelining support - Auto-follow 3xx redirects with max depth - Automatic gzip & deflate decoding - Streaming response processing - Streaming file uploads - HTTP proxy and SOCKS5 support - Basic Auth & OAuth - Connection-level & global middleware support - HTTP parser via http_parser.rb - Works wherever EventMachine runs: Rubinius, JRuby, MRI
Example Use
```ruby EventMachine.run { http = EventMachine::HttpRequest.new('http://google.com/').get :query => {'keyname' => 'value'}
# add callback for errors: http.errback { p 'Uh oh'; EM.stop }
# add callback for successful requests http.callback { p http.response_header.status p http.response_header p http.response
EventMachine.stop
} } ```
