异步HTTP组件 - react/http-client

(要求Workerman版本>=3.3.6)

安装：

composer require react/http-client

示例：

<?php
require_once __DIR__ . '/vendor/autoload.php';
use WorkermanWorker;
$worker = new Worker('text://0.0.0.0:6161');
$worker->onWorkerStart = function() {
    global   $client;
    $loop    = Worker::getEventLoop();
    $factory = new ReactDnsResolverFactory();
    $dns     = $factory->createCached('8.8.8.8', $loop);
    $factory = new ReactHttpClientFactory();
    $client = $factory->create($loop, $dns);
};
$worker->onMessage = function($connection, $host) {
    global     $client;
    $request = $client->request('GET', $host);
    $request->on('error', function(Exception $e) use ($connection) {
        $connection->send($e);
    });
    $request->on('response', function ($response) use ($connection) {
        $response->on('data', function ($data, $response) use ($connection) {
            $connection->send($data);
        });
    });
    $request->end();
};
Worker::runAll();

注意：

1、所有的异步编码必须在onXXX回调中编写

2、异步客户端需要的$loop变量请使用Worker::getEventLoop();返回值
