NAME
FCGI::Async::Request - Class to represent one active FastCGI request
SYNOPSIS
This module would not be used directly by a program using FCGI::Async
, but rather, objects in this class are passed into the on_request
callback of the containing FCGI::Async
object.
use FCGI::Async;
use IO::Async::Set::IO_Poll;
my $fcgi = FCGI::Async->new(
on_request => sub {
my ( $fcgi, $req ) = @_;
my $path = $req->param( "PATH_INFO" );
$req->print_stdout( "Status: 200 OK\r\n" .
"Content-type: text/plain\r\n" .
"\r\n" .
"You requested $path" );
$req->finish();
}
);
my $set = IO::Async::Set::IO_Poll->new();
$set->add( $fcgi );
$set->loop_forever;
FUNCTIONS
$hashref = $req->params
This method returns a reference to a hash containing a copy of the request parameters that had been sent by the webserver as part of the request.
$p = $req->param( $key )
This method returns the value of a single request parameter, or undef
if no such key exists.
$line = $req->read_stdin_line
This method works similarly to the <HANDLE>
operator. If at least one line of data is available then it is returned, including the linefeed, and removed from the buffer. If not, then any remaining partial line is returned and removed from the buffer. If no data is available any more, then undef
is returned instead.
$data = $req->read_stdin( $size )
This method works similarly to the read(HANDLE)
function. It returns the next block of up to $size bytes from the STDIN buffer. If no data is available any more, then undef
is returned instead.
$req->print_stdout( $data )
This method appends the given data to the STDOUT stream of the FastCGI request, sending it to the webserver to be sent to the client.
$req->print_stderr( $data )
This method appends the given data to the STDERR stream of the FastCGI request, sending it to the webserver.
$req->finish( $exitcode )
When the request has been dealt with, this method should be called to indicate to the webserver that it is finished. After calling this method, no more data may be appended to the STDOUT stream. At some point after calling this method, the request object will be removed from the containing FCGI::Async
object, once all the buffered outbound data has been sent.
If present, $exitcode
should indicate the numeric status code to send to the webserver. If absent, a value of 0
is presumed.
