 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规则。
安装：
[root@localhost www.fpm.com]# /usr/local/php734/bin/php /usr/bin/composer require workerman/http-client
Do not run Composer as root/super user! See https://getcomposer.org/root for details
Continue as root/super user [yes]? yes
Using version ^0.1.7 for workerman/http-client
./composer.json has been updated
Running composer update workerman/http-client
Loading composer repositories with package information
Updating dependencies
Nothing to modify in lock file
Installing dependencies from lock file (including require-dev)
Nothing to install, update or remove

實例：
爲了實現client請求測試，我們需要一個http服務端：
<?php
use Workerman\Worker;
use Workerman\Connection\TcpConnection;
use Workerman\Protocols\Http\Request;
require_once __DIR__ . '/vendor/autoload.php';
 
// 创建一个Worker监听2345端口，使用http协议通讯
$http_worker = new Worker("http://0.0.0.0:2345");
 
// 启动4个进程对外提供服务
$http_worker->count = 4;
 
// 接收到浏览器发送的数据时回复hello world给浏览器
$http_worker->onMessage = function(TcpConnection $connection, Request $request)
{
    // 向浏览器发送hello world
    $getParams=$request->get();
    $postParams=$request->post();
    $response["get"]=$getParams;
    $response["post"]=$postParams;
    $connection->send(json_encode($response));
};
 
// 运行worker
Worker::runAll();
然後運行http服務端：
[root@localhost www.fpm.com]# /usr/local/php734/bin/php httpServer.php start
Workerman[httpServer.php] start in DEBUG mode
----------------------------------------- WORKERMAN -----------------------------------------
Workerman version:4.0.22          PHP version:7.3.4
------------------------------------------ WORKERS ------------------------------------------
proto   user            worker          listen                 processes    status
tcp     root            none            http://0.0.0.0:2345    4             [OK]
---------------------------------------------------------------------------------------------
Press Ctrl+C to stop. Start success.
 
然後是咱們的http客戶端：
<?php
use Workerman\Worker;
require_once __DIR__ . '/vendor/autoload.php';
 
$worker = new Worker();
$worker->onWorkerStart = function(){
    $http = new Workerman\Http\Client();
 
    $http->get('http://127.0.0.1:2345/', function($response){
        var_dump("get:");
        var_dump($response->getStatusCode());
        var_dump(json_decode($response->getBody()));
    }, function($exception){
        var_dump("get:");
        echo $exception;
    });
 
    $http->post('http://127.0.0.1:2345/', ['key1'=>'value1','key2'=>'value2'], function($response){
        var_dump("post:");
        var_dump($response->getStatusCode());
        var_dump(json_decode($response->getBody()));
    }, function($exception){
        var_dump("post:");
        echo $exception;
    });
 
    $http->request('http://127.0.0.1:2345/', [
        'method'  => 'POST',
        'version' => '1.1',
        'headers' => ['Connection' => 'keep-alive'],
        'data'    => ['key3' => 'value3', 'key4'=>'value4'],
        'success' => function ($response) {
            var_dump("request:");
            var_dump(json_decode($response->getBody()));
        },
        'error'   => function ($exception) {
            var_dump("request:");
            echo $exception;
        }
    ]);
};
Worker::runAll();
客戶端實例運行：
[root@localhost www.fpm.com]# /usr/local/php734/bin/php httpClient.php start
Workerman[httpClient.php] start in DEBUG mode
------------------------------------- WORKERMAN --------------------------------------
Workerman version:4.0.22          PHP version:7.3.4
-------------------------------------- WORKERS ---------------------------------------
proto   user            worker          listen          processes    status
tcp     root            none            none            1             [OK]
--------------------------------------------------------------------------------------
Press Ctrl+C to stop. Start success.
string(4) "get:"
int(200)
object(stdClass)#16 (2) {
  ["get"]=>
  array(0) {
  }
  ["post"]=>
  array(0) {
  }
}
string(8) "request:"
object(stdClass)#35 (2) {
  ["get"]=>
  array(0) {
  }
  ["post"]=>
  object(stdClass)#9 (2) {
    ["key3"]=>
    string(6) "value3"
    ["key4"]=>
    string(6) "value4"
  }
}
string(5) "post:"
int(200)
object(stdClass)#26 (2) {
  ["get"]=>
  array(0) {
  }
  ["post"]=>
  object(stdClass)#28 (2) {
    ["key1"]=>
    string(6) "value1"
    ["key2"]=>
    string(6) "value2"
  }
}
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
