Version 0.8.9

Depends

C version

  * ((<libfcgi|URL:http://www.fastcgi.com/#TheDevKit>))(FastCGI Developer's Kit)

Pure Ruby Version

  * StringIO

Install

  $ ruby install.rb config
    (Pure Ruby Version: ruby install.rb config --without-ext)
    (Some systems need: ruby install.rb config -- --with-fcgi-include=/usr/local/include --with-fcgi-lib=/usr/local/lib)
  $ ruby install.rb setup
  # ruby install.rb install

Usage

Class Method

— FCGI.accept

    Returns FCGI instance

— FCGI.each

— FCGI.each_request

— FCGI.is_cgi?

— FCGI.each_cgi

    Automatically detects whether this program is running under the FastCGI
    environment, and generates a 'CGI' type object for each request. Also
    installs signal handlers for graceful handling of SIGPIPE (which may
    occur if a client gives up on a request before it is complete) and
    SIGUSR1 (generated by Apache for a 'graceful' exit)

    If you are using the HTML output methods you can also pass the HTML type
    e.g. FCGI.each_cgi('html3') do ... end

    However, you should beware that the CGI library is quite slow when
    used in this way, as it dynamically adds a large number of methods
    to itself each time a new instance is created.

Instance Method

— FCGI#finish

    Finish

— FCGI#in

    Returns Stream or StringIO

— FCGI#out

    Returns Stream or StringIO

— FCGI#err

    Returns Stream or StringIO

— FCGI#env

    Returns Environment(Hash)

Sample

Using the FastCGI native interface:

  #!/usr/bin/ruby
  require "fcgi"

  FCGI.each {|request|
    out = request.out
    out.print "Content-Type: text/plain\r\n"
    out.print "\r\n"
    out.print Time.now.to_s
    request.finish
  }

Using the CGI-compatible interface, which works both as a standalone CGI and under FastCGI with no modifications:

  #!/usr/bin/ruby
  require "fcgi"

  FCGI.each_cgi {|cgi|
    name = cgi['name'][0]
    puts cgi.header
    puts "You are #{name} " if name
    puts "Connecting from #{cgi.remote_addr}"
  }

Note: you can’t reference CGI environment variables using ENV when under FastCGI. It is recommended that you use the CGI-generated methods, e.g. cgi.remote_addr as above.

If you need to access environment variables directly, perhaps extra ones set in your Apache config, then use cgi.env_table[‘REMOTE_ADDR’] instead. This isn’t quite as portable because env_table is a private method in the standard CGI library.
