PHP swoole中http_server的配置与使用方法实例分析

?php
//创建一个http server服务
$server = new swoole_http_server('0.0.0.0', 8888);
 
$server->set([
  'package_max_length' => 1024 * 1024 * 10,
  //设置文件上传的临时目录
  'upload_tmp_dir' => __DIR__ . '/uploads/',
]);
 
//设置request事件回调
//函数有两个参数：
//swoole_http_request对象，负责http请求相关信息
//swoole_http_response对象，负责向客户端响应相关信息
$server->on('request', function (swoole_http_request $request, swoole_http_response $response) {
  //请求的头部信息
  var_dump($request->header);
 
  //请求相关的服务器信息，相当于PHP中的$_SERVER
  var_dump($request->server);
 
  //请求的GET参数，相当于PHP中的$_GET
  var_dump($request->get);
 
  //请求的POST参数，相当于PHP中的$_POST
  var_dump($request->post);
 
  //请求的COOKIE信息
  var_dump($request->cookie);
 
  //文件上传信息，文件大小不超过package_max_length的值
  var_dump($request->files);
 
  //获取原始POST请求数据，相当于fopen('php://input');
  var_dump($request->rawContent());
 
  //获取完整http请求报文
  var_dump($request->getData());
 
  //向客户端发送信息
  $response->end('hello');
});
 
//启动服务
$server->start();
