workerman/http-client

说明

workerman/http-client是一个异步http客户端组件。所有请求响应异步非阻塞，内置连接池，消息请求和响应符合PSR7规范。

安装：

composer require workerman/http-client

示例：

use Workerman\Worker;

require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker();
$worker->onWorkerStart = function () {
    $http = new Workerman\Http\Client();

    $http->get('https://example.com/', function ($response) {
        var_dump($response->getStatusCode());
        echo $response->getBody();
    }, function ($exception) {
        echo $exception;
    });

    $http->post('https://example.com/', ['key1' => 'value1', 'key2' => 'value2'], function ($response) {
        var_dump($response->getStatusCode());
        echo $response->getBody();
    }, function ($exception) {
        echo $exception;
    });

    $http->request('https://example.com/', [
        'method' => 'POST',
        'version' => '1.1',
        'headers' => ['Connection' => 'keep-alive'],
        'data' => ['key1' => 'value1', 'key2' => 'value2'],
        'success' => function ($response) {
            echo $response->getBody();
        },
        'error' => function ($exception) {
            echo $exception;
        }
    ]);
};
Worker::runAll();

Optinons 选项

<?php
require __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
$worker = new Worker();
$worker->onWorkerStart = function(){
    $options = [
        'max_conn_per_addr' => 128, // 每个地址最多维持多少并发连接
        'keepalive_timeout' => 15,  // 连接多长时间不通讯就关闭
        'connect_timeout'   => 30,  // 连接超时时间
        'timeout'           => 30,  // 等待响应的超时时间
    ];
    $http = new Workerman\Http\Client($options);

    $http->get('http://example.com/', function($response){
        var_dump($response->getStatusCode());
        echo $response->getBody();
    }, function($exception){
        echo $exception;
    });
};
Worker::runAll();

协程用法

注意
协程用法需要workerman>=5.0，workerman/http-client>=2.0.0 并安装 composer require revolt/event-loop ^1.0.0

use Workerman\Worker;

require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker();
$worker->onWorkerStart = function () {
    $http = new Workerman\Http\Client();

    $response = $http->get('https://example.com/');
    var_dump($response->getStatusCode());
    echo $response->getBody();

    $response = $http->post('https://example.com/', ['key1' => 'value1', 'key2' => 'value2']);
    var_dump($response->getStatusCode());
    echo $response->getBody();

    $response = $http->request('https://example.com/', [
        'method' => 'POST',
        'version' => '1.1',
        'headers' => ['Connection' => 'keep-alive'],
        'data' => ['key1' => 'value1', 'key2' => 'value2'],
    ]);
    echo $response->getBody();
};
Worker::runAll();

当不设置回调函数时，客户端会用同步的方式返回异步请求结果，请求过程不阻塞当前进程，也就是可以并发处理请求。

注意：

1、项目首先要加载require __DIR__ . '/vendor/autoload.php';

2、所有的异步编码必须在onXXX回调中编写

3、支持基于workerman开发的所有项目，包括GatewayWorker、PHPSocket.io等
