АТРИБУТЫ

Mojo::Transaction implements the following attributes.

connection

    my $connection = $tx->connection;
    $tx            = $tx->connection($connection);

Connection identifier or socket.

keep_alive

    my $keep_alive = $tx->keep_alive;
    $tx            = $tx->keep_alive(1);

Connection can be kept alive.

kept_alive

    my $kept_alive = $tx->kept_alive;
    $tx            = $tx->kept_alive(1);

Connection has been kept alive.

local_address

    my $local_address = $tx->local_address;
    $tx               = $tx->local_address($address);

Local interface address.

local_port

    my $local_port = $tx->local_port;
    $tx            = $tx->local_port($port);

Local interface port.

on_finish

    my $cb = $tx->on_finish;
    $tx    = $tx->on_finish(sub {...});

Callback to be invoked when the transaction has been finished.

    $tx->on_finish(sub {
        my $self = shift;
    });

on_resume

    my $cb = $tx->on_resume;
    $tx    = $tx->on_resume(sub {...});

Callback to be invoked whenever the transaction is resumed.

    $tx          = $tx->previous(Mojo::Transaction->new);

Previous transaction that triggered this followup transaction.

remote_address

    $tx             = $tx->remote_port($port);

МЕТОДЫ

Mojo::Transaction inherits all methods from Mojo::Base and implements the following new ones.

client_read

    $tx = $tx->client_read($chunk);

Read and process client data.

client_write

    my $chunk = $tx->client_write;

Write client data.

error

    my $message          = $message->error;
    my ($message, $code) = $message->error;

Parser errors and codes.

is_done

    my $done = $tx->is_done;

Check if transaction is done.

is_websocket

    my $is_websocket = $tx->is_websocket;

Check if transaction is a WebSocket.

is_writing

    my $writing = $tx->is_writing;

Check if transaction is writing.

req

    my $req = $tx->req;

Transaction request, usually a Mojo::Message::Request object.

res

    my $res = $tx->res;

Transaction response, usually a Mojo::Message::Response object.

resume

    $tx = $tx->resume;

Resume transaction.

server_close

    $tx = $tx->server_close;

Transaction closed.

server_read

    $tx = $tx->server_read($chunk);

Read and process server data.

server_write

    my $chunk = $tx->server_write;

Write server data.

success

    my $res = $tx->success;

Returns the Mojo::Message::Response object (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.

    if (my $res = $tx->success) {
        print $res->body;
    }
    else {
        my ($message, $code) = $tx->error;
        if ($code) {
            print "$code $message response.\n";
        }
        else {
            print "Connection error: $message\n";
        }
    }

Error messages can be accessed with the error method of the transaction object.
