FastCGI is a language independent, scalable, open extension to CGI that provides high performance without the limitations of server specific APIs. This version aims to be compatible with both 1.8.x and 1.9.x versions of Ruby, and also will be ported to 2.0.x. It has been hacked to work with Ruby 3.0.x.

Pure Ruby Version¶ ↑

* StringIO

Install¶ ↑

$ gem install fcgi

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 instead. This isn’t quite as portable because env_table is a private method in the standard CGI library.
