# setDefer setDefer() ~~~ bool setDefer([bool $is_defer = true]); ~~~ * $is_defer：bool值，为true时，表明该Client要延迟收包，为false时，表明该Client非延迟收包，默认值为true * 返回值：设置成功返回true，否则返回false。只有一种情况会返回false，当设置defer(true)并发包后，尚未recv()收包，就设置defer(false)，此时返回false。 * 如果需要进行延迟收包，需要在发包之前调用 ~~~php <?php $server = new Swoole\Http\Server("127.0.0.1", 9502, SWOOLE_BASE); $server->set([ 'worker_num' => 1, ]); $server->on('Request', function ($request, $response) { $tcpclient = new Swoole\Coroutine\Client(SWOOLE_SOCK_TCP); $tcpclient->connect('127.0.0.1', 9501，0.5) $tcpclient->send("hello world\n"); $redis = new Swoole\Coroutine\Redis(); $redis->connect('127.0.0.1', 6379); $redis->setDefer(); $redis->get('key'); $httpclient = new Swoole\Coroutine\Http\Client('0.0.0.0', 9599); $httpclient->setHeaders(['Host' => "api.mp.qq.com"]); $httpclient->set([ 'timeout' => 1]); $httpclient->setDefer(); $httpclient->get('/'); $tcp_res = $tcpclient->recv(); $redis_res = $redis->recv(); $http_res = $httpclient->recv(); $response->end('Test End'); }); $server->start(); ~~~
