ATTRIBUTES

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.
previous
my $previous = $tx->previous;
$tx = $tx->previous(Mojo::Transaction->new);Previous transaction that triggered this followup transaction.
say $tx->previous->req->url->path;remote_address
my $remote_address = $tx->remote_address;
$tx = $tx->remote_address($address);Remote interface address.
remote_port
my $remote_port = $tx->remote_port;
$tx = $tx->remote_port($port);Remote interface port.
req
my $req = $tx->req;
$tx = $tx->req(Mojo::Message::Request->new);HTTP 1.1 request, defaults to a Mojo::Message::Request object.
res
my $res = $tx->res;
$tx = $tx->res(Mojo::Message::Response->new);HTTP 1.1 response, defaults to a Mojo::Message::Response object.
METHODS
Mojo::Transaction inherits all methods from Mojo::EventEmitter and implements the following new ones.
client_close
$tx->client_close;Transaction closed.
client_read
$tx->client_read($chunk);Read and process client data.
client_write
my $chunk = $tx->client_write;Write client data.
connection
my $connection = $tx->connection;
$tx = $tx->connection($connection);Connection identifier or socket.
error
my $message = $message->error;
my ($message, $code) = $message->error;Parser errors and codes.
is_finished
my $success = $tx->is_finished;Check if transaction is finished.
is_websocket
my $false = $tx->is_websocket;False.
is_writing
my $success = $tx->is_writing;Check if transaction is writing.
resume
$tx = $tx->resume;Resume transaction.
server_close
$tx->server_close;Transaction closed.
server_read
$tx->server_read($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) {
say $res->body;
}
else {
my ($message, $code) = $tx->error;
if ($code) {
say "$code $message response.";
}
else {
say "Connection error: $message";
}
}Error messages can be accessed with the error method of the transaction object.
