3.4.6 - Coroutine／Http／Client->recv.md

Coroutine\Http\Client->recv

接收消息。与setDefer或upgrade配合使用。

function Coroutine\Http\Client->recv(float $timeout = -1);

• $timeout 为upgrade升级为websocket时可用的超时参数
• $timeout 设置超时，优先使用指定的参数，其次使用set方法中传入的timeout配置
• 未设置任何超时，将持续等待

$timeout参数需要2.1.2或更高版本

Http

go(function () {
    $cli = new Swoole\Coroutine\Http\Client('127.0.0.1', 80);
    $cli->setHeaders([
        'Host' => "localhost",
        "User-Agent" => 'Chrome/49.0.2587.3',
        'Accept' => 'text/html,application/xhtml+xml,application/xml',
        'Accept-Encoding' => 'gzip',
    ]);
    $cli->set([ 'timeout' => 1]);
	$cli->setDefer();
    $cli->get('/');
	co::sleep(1);
	$data = $cli->recv();
});

WebSocket

go(function () {
    $cli = new Co\http\Client("127.0.0.1", 9501);
    $ret = $cli->upgrade("/");

    if ($ret) {
        while(true) {
            $cli->push("hello");
            var_dump($cli->recv());
            co::sleep(0.1);
        }
    }
});
