httpclient - HTTP accessing library. Gem Version

Copyright (C) 2000-2015 NAKAMURA, Hiroshi [email protected].

'httpclient' gives something like the functionality of libwww-perl (LWP) in Ruby. 'httpclient' formerly known as 'http-access2'.

See HTTPClient for documentation.


  • methods like GET/HEAD/POST/* via HTTP/1.1.
  • HTTPS(SSL), Cookies, proxy, authentication(Digest, NTLM, Basic), etc.
  • asynchronous HTTP request, streaming HTTP request.
  • debug mode CLI.
  • by contrast with net/http in standard distribution;
    • Cookies support
    • MT-safe
    • streaming POST (POST with File/IO)
    • Digest auth
    • Negotiate/NTLM auth for WWW-Authenticate (requires net/ntlm module; rubyntlm gem)
    • NTLM auth for Proxy-Authenticate (requires 'win32/sspi' module; rubysspi gem)
    • extensible with filter interface
    • you don't have to care HTTP/1.1 persistent connection (httpclient cares instead of you)
  • Not supported now
    • Cache
    • Rather advanced HTTP/1.1 usage such as Range, deflate, etc. (of course you can set it in header by yourself)

httpclient command

Usage: 1) httpclient get
Usage: 2) httpclient

For 1) it issues a GET request to the given URI and shows the wiredump and the parsed result. For 2) it invokes irb shell with the binding that has a HTTPClient as 'self'. You can call HTTPClient instance methods like;

get "", :q => :ruby

httpclient/session.rb is based on http-access.rb in http-access/0.0.4. Some part of it is copyrighted by Maebashi-san who made and published http-access/0.0.4. http-access/0.0.4 did not include license notice but when I asked Maebashi-san he agreed that I can redistribute it under the same terms of Ruby. Many thanks to Maebashi-san.
