DESCRIPTION
Mojo::Client is a full featured async io HTTP 1.1 and WebSocket client with IPv6
, TLS
, epoll
and kqueue
support.
Optional modules IO::KQueue, IO::Epoll, IO::Socket::IP and IO::Socket::SSL are supported transparently and used if installed.
ATTRIBUTES
Mojo::Client implements the following attributes.
app
my $app = $client->app;
$client = $client->app(MyApp->new);
A Mojo application to associate this client with. If set, local requests will be processed in this application.
cookie_jar
my $cookie_jar = $client->cookie_jar;
$client = $client->cookie_jar(Mojo::CookieJar->new);
Cookie jar to use for this clients requests, by default a Mojo::CookieJar object.

ioloop
my $loop = $client->ioloop;
$client = $client->ioloop(Mojo::IOLoop->new);
Loop object to use for io operations, by default a Mojo::IOLoop object will be used.
keep_alive_timeout
my $keep_alive_timeout = $client->keep_alive_timeout;
$client = $client->keep_alive_timeout(15);
Timeout in seconds for keep alive between requests, defaults to 15
.
log
my $log = $client->log;
$client = $client->log(Mojo::Log->new);
A Mojo::Log object used for logging, by default the application log will be used.
max_connections
my $max_connections = $client->max_connections;
$client = $client->max_connections(5);
Maximum number of keep alive connections that the client will retain before it starts closing the oldest cached ones, defaults to 5
.
max_redirects
my $max_redirects = $client->max_redirects;
$client = $client->max_redirects(3);
Maximum number of redirects the client will follow before it fails, defaults to 0
.
tx
$client->tx;
The last finished transaction, only available from callbacks, usually a Mojo::Transaction::HTTP or Mojo::Transaction::WebSocket object.
websocket_timeout
my $websocket_timeout = $client->websocket_timeout;
$client = $client->websocket_timeout(300);
Timeout in seconds for WebSockets to be idle, defaults to 300
.
METHODS
Mojo::Client inherits all methods from Mojo::Base and implements the following new ones.
new
my $client = Mojo::Client->new;
Construct a new Mojo::Client object. Use singleton
if you want to share keep alive connections with other clients.
async
my $async = $client->async;
Clone client instance and start using the global shared Mojo::IOLoop singleton if it is running. Note that all cloned clients have their own keep alive connection queue, so you can quickly run out of file descriptors with too many active clients.
build_form_tx
my $tx = $client->build_form_tx('http://kraih.com/foo' => {test => 123});
my $tx = $client->build_form_tx(
'http://kraih.com/foo',
'UTF-8',
{test => 123}
);
my $tx = $client->build_form_tx(
'http://kraih.com/foo',
{test => 123},
{Expect => 'fun'}
);
