NAME

Mojolicious::Plugin::CGI - Run CGI script from Mojolicious

VERSION

0.24

DESCRIPTION

This plugin enable Mojolicious to run Perl CGI scripts. It does so by forking a new process with a modified environment and reads the STDOUT in a non-blocking manner.

SYNOPSIS

Standard usage

use Mojolicious::Lite;
plugin CGI => [ "/cgi-bin/script" => "/path/to/cgi/script.pl" ];

Using the code above is enough to run script.pl when accessing http://localhost:3000/cgi-bin/script.

Complex usage

plugin CGI => {
  # Specify the script and mount point
  script => "/path/to/cgi/script.pl",
  route  => "/some/route",

  # %ENV variables visible from inside the CGI script
  env => {}, # default is \%ENV

  # Path to where STDERR from cgi script goes
  errlog => "/path/to/file.log",

  # The "before" hook is called before script start
  # It receives a Mojolicious::Controller which can be modified
  before => sub {
    my $c = shift;
    $c->req->url->query->param(a => 123);
  },
};

The above contains all the options you can pass on to the plugin.

Running code refs

plugin CGI => {
  route => "/some/path",
  run   => sub {
    my $cgi = CGI->new;
    # ...
  }
};

Instead of calling a script, you can run a code block when accessing the route. This is (pretty much) safe, even if the code block modifies global state, since it runs in a separate fork/process.

Support for semicolon in query string

plugin CGI => {
  support_semicolon_in_query_string => 1,
  ...
};

The code above need to be added before other plugins or handler which use "url" in Mojo::Message::Request. It will inject a before_dispatch hook which saves the original QUERY_STRING, before it is split on "&" in Mojo::Parameters.

ATTRIBUTES

env

Holds a hash ref containing the environment variables that should be used when starting the CGI script. Defaults to %ENV when this module was loaded.

ioloop

Holds a Mojo::IOLoop object.

METHODS

emulate_environment

%env = $self->emulate_environment($c);

Returns a hash which contains the environment variables which should be used by the CGI script.

In addition to "env", these dynamic variables are set:

CONTENT_LENGTH, CONTENT_TYPE, HTTP_COOKIE, HTTP_HOST, HTTP_IF_NONE_MATCH,
HTTP_REFERER, HTTP_USER_AGENT, HTTPS, PATH, PATH_INFO, QUERY_STRING,
REMOTE_ADDR, REMOTE_HOST, REMOTE_PORT, REMOTE_USER, REQUEST_METHOD,
SCRIPT_NAME, SERVER_PORT, SERVER_PROTOCOL.

Additional static variables:

GATEWAY_INTERFACE = "CGI/1.1"
SERVER_ADMIN = $ENV{USER}
SCRIPT_FILENAME = Script name given as argument to register.
SERVER_NAME = Sys::Hostname::hostname()
SERVER_SOFTWARE = "Mojolicious::Plugin::CGI"

register

$self->register($app, [ $route => $script ]);
$self->register($app, %args);
$self->register($app, \%args);

route and path need to exist as keys in %args unless given as plain arguments.

$route can be either a plain path or a route object.
