HTTP Client

A simple Net::HTTP wrapper with multi-part request, file upload and cookie-jar support.

Install

gem install http-client

Example

require 'http-client'
res = HTTP::Client::Request.new(:get, "http://a.b/", max_redirects: 2).execute

# save a few keystrokes.
res = HTTP::Client.get("http://a.b/", max_redirects: 2)
res = HTTP::Client.put("http://a.b/", files: {pic: "kittens.jpg"}, query: {title: "the usual suspects"})
res = HTTP::Client.post("http://a.b/", auth: {username: "test", password: "test"}, headers: {'x-a' => 'b'})
res = HTTP::Client.delete("http://a.b/", auth: {username: "test", password: "test"});

API

HTTP::Client
    .get(uri, arguments = {})
    .put(uri, arguments = {})
    .post(uri, arguments = {})
    .head(uri, arguments = {})
    .trace(uri, arguments = {})
    .delete(uri, arguments = {})
    .options(uri, arguments = {})

HTTP::Client
    .open_timeout=
    .read_timeout=
    .ssl_timeout=

HTTP::Client::Request
    .new(verb, uri, arguments = {})
    #execute

HTTP::Client::Response
    .new(net_http_response, last_effective_uri)
    #code
    #body
    #headers
    #last_effective_uri

Exceptions

HTTP::Client rescues most Net::HTTP, Zlib and URI related exceptions and re-raises them as an appropriate exception. You can retrieve the original exception using the HTTP::Client::Error#original_error instance method.

HTTP::Client::Error
  HTTP::Client::Error::URI
  HTTP::Client::Error::Zlib
  HTTP::Client::Error::Timeout
  HTTP::Client::Error::Transport
  HTTP::Client::Error::Argument

Default behaviour

SSL

• By default peer verification is done. You can turn this off by passing ssl_verfy: HTTP::Client::SSL_VERIFY_NONE option.

Redirects

• By default the client does not follow redirects. You can enable this with a non-zero max_redirects option.
• 301, 302 and 303 redirects are always followed with a GET method.
• 307 and 308 redirects preserve original request method & body.
