NAME
Mojo::Client - Async IO HTTP 1.1 And WebSocket Client
SYNOPSIS
use Mojo::Client;
my $client = Mojo::Client->new;
$client->get(
'http://kraih.com' => sub {
my $self = shift;
print $self->res->code;
}
)->process;DESCRIPTION
Mojo::Client is a full featured async io HTTP 1.1 and WebSocket client with IPv6, TLS, epoll and kqueue support.
It implements the most common HTTP verbs. If you need something more custom you can create your own Mojo::Transaction::HTTP objects and queue them. All of the verbs take an optional set of headers as a hash or hash reference, as well as an optional callback sub reference.
Optional modules IO::KQueue, IO::Epoll, IO::Socket::INET6 and IO::Socket::SSL are supported transparently and used if installed.
ATTRIBUTES
Mojo::Client implements the following attributes.
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.
default_cb
my $cb = $client->default_cb;
$client = $client->default_cb(sub {...});A default callback to use if your request does not specify a callback.
$client->default_cb(sub {
my ($self, $tx) = @_;
});ioloop
my $loop = $client->ioloop;
$client = $client->ioloop(Mojo::IOLoop->new);Loop object to use for io operations, by default it will use the global Mojo::IOLoop singleton. You can force the client to block on process by creating a new loop object.
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.
max_keep_alive_connections
my $max_keep_alive_connections = $client->max_keep_alive_connections;
$client = $client->max_keep_alive_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 3.
tls_ca_file
my $tls_ca_file = $client->tls_ca_file;
$client = $client->tls_ca_file('/etc/tls/cacerts.pem');TLS certificate authority file to use, defaults to the MOJO_CA_FILE environment variable. Note that IO::Socket::SSL must be installed for HTTPS support.
tls_verify_cb
my $tls_verify_cb = $client->tls_verify_cb;
$client = $client->tls_verify_cb(sub {...});Callback to verify your TLS connection, by default the client will accept most certificates. Note that IO::Socket::SSL must be installed for HTTPS support.
tx
$client->tx;The last finished transaction, only available from callbacks.
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 and cookies with other clients
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.
delete
$client = $client->delete('http://kraih.com' => sub {...});
$client = $client->delete(
'http://kraih.com' => (Connection => 'close') => sub {...}
);Send a HTTP DELETE request.
finish
$client->finish;Finish the WebSocket connection, only available from callbacks.
get
$client = $client->get('http://kraih.com' => sub {...});
$client = $client->get(
'http://kraih.com' => (Connection => 'close') => sub {...}
);Send a HTTP GET request.
head
$client = $client->head('http://kraih.com' => sub {...});
$client = $client->head(
'http://kraih.com' => (Connection => 'close') => sub {...}
);Send a HTTP HEAD request.
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.
post
$client = $client->post('http://kraih.com' => sub {...});
$client = $client->post(
'http://kraih.com' => (Connection => 'close') => sub {...}
);
$client = $client->post(
'http://kraih.com',
(Connection => 'close'),
'message body',
sub {...}
);
$client = $client->post(
'http://kraih.com' => (Connection => 'close') => 'Hi!' => sub {...}
);Send a HTTP POST request.
post_form
$client = $client->post_form('/foo' => {test => 123}, sub {...});
$client = $client->post_form(
'/foo',
'UTF-8',
{test => 123},
sub {...}
);
$client = $client->post_form(
'/foo',
{test => 123},
{Expect => '100-continue'},
sub {...}
);
$client = $client->post_form(
'/foo',
'UTF-8',
{test => 123},
{Expect => '100-continue'},
sub {...}
);Send a HTTP POST request with form data.
process
$client = $client->process;
$client = $client->process(@transactions);
$client = $client->process(@transactions => sub {...});Process all queued transactions. Will be blocking unless you have a global shared ioloop.
put
$client = $client->put('http://kraih.com' => sub {...});
$client = $client->put(
'http://kraih.com' => (Connection => 'close') => sub {...}
);
$client = $client->put(
'http://kraih.com' => (Connection => 'close') => 'Hi!' => sub {...}
);Send a HTTP PUT request.
queue
$client = $client->queue(@transactions);
$client = $client->queue(@transactions => sub {...});Queue a list of transactions for processing. HTTP 1.1 transactions can also be pipelined by wrapping them in an arrayref. Note that following redirects and WebSocket upgrades don't work for pipelined transactions.
$client->queue([$tx, $tx2] => sub {
my ($self, $p) = @_;
});receive_message
$client->receive_message(sub {...});Receive messages via WebSocket, only available from callbacks.
$client->receive_message(sub {
my ($self, $message) = @_;
});req
my $req = $client->req;The request object of the last finished transaction, only available from callbacks.
res
my $res = $client->res;The response object of the last finished transaction, only available from callbacks.

websocket
$client = $client->websocket('ws://localhost:3000' => sub {...});
$client = $client->websocket(
'ws://localhost:3000' => ('User-Agent' => 'Agent 1.0') => sub {...}
);Open a WebSocket connection with transparent handshake.
