Mojo::Transaction - Transaction base class
package Mojo::Transaction::MyTransaction; use Mojo::Base 'Mojo::Transaction'; sub client_read {...} sub client_write {...} sub server_read {...} sub server_write {...}
Mojo::Transaction is an abstract base class for transactions.
Mojo::Transaction inherits all events from Mojo::EventEmitter and can emit the following new ones.
$tx->on(connection => sub { my ($tx, $connection) = @_; ... });
Emitted when a connection has been assigned to transaction.
$tx->on(finish => sub { my $tx = shift; ... });
Emitted when transaction is finished.
$tx->on(resume => sub { my $tx = shift; ... });
Emitted when transaction is resumed.
Mojo::Transaction implements the following attributes.
my $kept_alive = $tx->kept_alive; $tx = $tx->kept_alive(1);
Connection has been kept alive.
my $address = $tx->local_address; $tx = $tx->local_address('127.0.0.1');
Local interface address.
my $port = $tx->local_port; $tx = $tx->local_port(8080);
Local interface port.
my $port = $tx->remote_port; $tx = $tx->remote_port(8081);
Remote interface port.
my $req = $tx->req; $tx = $tx->req(Mojo::Message::Request->new);
HTTP request, defaults to a Mojo::Message::Request object.
my $res = $tx->res; $tx = $tx->res(Mojo::Message::Response->new);
HTTP response, defaults to a Mojo::Message::Response object.
Mojo::Transaction inherits all methods from Mojo::EventEmitter and implements the following new ones.
$tx->client_close; $tx->client_close(1);
Transaction closed client-side, no actual connection close is assumed by default, used to implement user agents.
$tx->client_read($bytes);
Read data client-side, used to implement user agents. Meant to be overloaded in a subclass.
my $bytes = $tx->client_write;
Write data client-side, used to implement user agents. Meant to be overloaded in a subclass.
my $connection = $tx->connection; $tx = $tx->connection($connection);
Connection identifier or socket.
my $err = $tx->error; my ($err, $code) = $tx->error;
Error and code.
my $bool = $tx->is_finished;
Check if transaction is finished.
my $false = $tx->is_websocket;
False.
my $bool = $tx->is_writing;
Check if transaction is writing.
$tx = $tx->resume;
Resume transaction.
my $address = $tx->remote_address; $tx = $tx->remote_address('127.0.0.1');
Remote interface address.
$tx->server_close;
Transaction closed server-side, used to implement web servers.
$tx->server_read($bytes);
Read data server-side, used to implement web servers. Meant to be overloaded in a subclass.
my $bytes = $tx->server_write;
Write data server-side, used to implement web servers. Meant to be overloaded in a subclass.
my $res = $tx->success;
Returns the Mojo::Message::Response object from "res" if transaction was successful or undef otherwise. Connection and parser errors have only a message in "error", 400 and 500 responses also a code.
undef
# Sensible exception handling if (my $res = $tx->success) { say $res->body } else { my ($err, $code) = $tx->error; say $code ? "$code response: $err" : "Connection error: $err"; }
