cgi::emulate::psgi
CGI::Emulate::PSGI(3pm) User Contributed Perl Documentation CGI::Emulate::PSGI(3pm)NAME
CGI::Emulate::PSGI - PSGI adapter for CGI
SYNOPSIS
my $app = CGI::Emulate::PSGI->handler(sub {
# Existing CGI code
});
DESCRIPTION
This module allows an application designed for the CGI environment to run in a PSGI environment, and thus on any of the backends that PSGI
supports.
It works by translating the environment provided by the PSGI specification to one expected by the CGI specification. Likewise, it captures
output as it would be prepared for the CGI standard, and translates it to the format expected for the PSGI standard using CGI::Parse::PSGI
module.
CGI.pm
If your application uses CGI, be sure to cleanup the global variables in the handler loop yourself, so:
my $app = CGI::Emulate::PSGI->handler(sub {
use CGI;
CGI::initialize_globals();
my $q = CGI->new;
# ...
});
Otherwise previous request variables will be reused in the new requests.
Alternatively, you can install and use CGI::Compile from CPAN and compiles your existing CGI scripts into a sub that is perfectly ready to
be converted to PSGI application using this module.
my $sub = CGI::Compile->compile("/path/to/script.cgi");
my $app = CGI::Emulate::PSGI->handler($sub);
This will take care of assigning an unique namespace for each script etc. See CGI::Compile for details.
You can also consider using CGI::PSGI but that would require you to slightly change your code from:
my $q = CGI->new;
# ...
print $q->header, $output;
into:
use CGI::PSGI;
my $app = sub {
my $env = shift;
my $q = CGI::PSGI->new($env);
# ...
return [ $q->psgi_header, [ $output ] ];
};
See CGI::PSGI for details.
METHODS
handler
my $app = CGI::Emulate::PSGI->handler($code);
Creates a PSGI application code reference out of CGI code reference.
emulate_environment
my %env = CGI::Emulate::PSGI->emulate_environment($env);
Creates an environment hash out of PSGI environment hash. If your code or framework just needs an environment variable emulation, use
this method like:
local %ENV = (%ENV, CGI::Emulate::PSGI->emulate_environment($env));
# run your application
If you use "handler" method to create a PSGI environment hash, this is automatically called in the created application.
