#http\Client http\Client::enqueue(http\Client\Request $request[, callable $cb])

Add another http\Client\Request to the request queue. If the optional callback $cb returns true, the request will be automatically dequeued.

Note:
The http\Client\Response object resulting from the request is always stored internally to be retrieved at a later time, even when $cb is used.

If you are about to send a lot of requests and do not need the response after executing the callback, you can use http\Client::getResponse() within the callback to keep the memory usage level as low as possible.

See http\Client::dequeue() and http\Client::send().

Params:#

• http\Client\Request $request#
  The request to enqueue.
• Optional callable $cb# as function(\http\Response $response#) : ?bool
  A callback to automatically call when the request has finished.

Returns:#

• http\Client, self.

Throws:#

• http\Exception\InvalidArgumentException
• http\Exception\BadMethodCallException
• http\Exception\RuntimeException

Example:#

(new http\Client)->enqueue(new http\Client\Request("GET", "http://php.net"), 
    function(http\Client\Response $res) {
        printf("%s returned %d\n", $res->getTransferInfo("effective_url"), $res->getResponseCode());
        return true; // dequeue
})->send();

Yields:

http://php.net/ returned 200
