SYNOPSIS

            

              
              
sub handler {
    my ($self, $env, $request, $response, $session) = @_;
    ...
    sub (GET) {
        $response->header("Content-Type" => "text/plain");
        $response->body("hello, goodbye");
        return $response->finalize(200);
    }
}
# or using a callback
sub handler {
    ...
    sub (GET) {
        $response->header("Content-Type" => "text/plain");
        $response->body(sub {
            my $writer = shift;
            $writer->write("What is up?");
            $writer->close();
        });
        return $response->finalize(200);
    }
}
            
          

METHODS

header

This method expects a list of headers to add to the response. For example:

            

              
              
$response->header("Content-Type" => "text/plain");
$response->header("Content-Length" => 1234, "X-Foo" => "bar");
            
          

If the header has already been set this will add another value to it and the response will include the same header multiple times. To replace a header that has already been set, remove the existing value first:

            

              
              
$response->headers->remove("X-Foo");
            
          

headers

Returns a Hash::MultiValue of all headers that have been set to be sent with the response.

cookie

If called with no arguments this will return the names of all cookies that have been set to be sent with the response. Otherwise, this method expects a list of cookies to add to the response. For example:

            

              
              
$response->cookie("foo" => {
    'value'   => "test",
    'path'    => "/",
    'domain'  => ".example.com",
    'expires' => time + 24 * 60 * 60,
});
            
          

The hashref may contain the keys value, domain, expires, path, httponly, and secure. expires can take a string or an integer (as an epoch time) and does not convert string formats like +3M.

cookies

Returns a Hash::MultiValue of all cookies that have been set to be sent with the response.

body

Send buffered output to the client. Anything sent to the client with this method will be buffered until finalize is called. For example:

            

              
              
$response->body("hello");
$response->body("goodbye", "world");
            
          

If a buffered response is not desired then the body may be a callback to send a streaming response to the client. Any headers or response codes set in the callback will be ignored as they must all be set beforehand. Any body set before a callback is set will also be ignored. For example:

            

              
              
$response->body(sub {
    my $writer = shift;
    $writer->write("Hello, world!");
    $writer->close();
    return;
});
            
          

finalize

This requires one argument: the HTTP status code of the response. It will then send a PSGI compatible response to the client. For example:

            

              
              
# or hard code it
$response->finalize(200);
