remote_address

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

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

METHODS

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.
