PHP的HTTP客户端Guzzle简单使用发起请求

执行Composer命令下载Guzzle

 composer require guzzlehttp/guzzle

【GET请求】
<?php

  require './vendor/autoload.php';
 
  //实例化客户端
  $client = new GuzzleHttp\Client();
 
  //构造url
  $url = 'https://www.baidu.com';
 
  //get请求
  $res = $client->request('GET', $url);
 
  //返回状态码
  echo $res->getStatusCode();
 
  //连贯操作
  //$res = $client->request('GET', $url)->getBody()->getContents();
 ?>

【POST请求】

<?php 
  require './vendor/autoload.php';
 
  //实例化客户端
  $client = new GuzzleHttp\Client(); 
 
  //构造url
  $url = 'https://www.baidu.com';
 
  //post请求
  $res = $client->request('POST', $url, [
    'form_params' => [
      'name'=>'lws',
      'sex'=>'nan'
    ]
  ]);
 
  //返回状态码
  echo $res->getStatusCode();
?>
