Linux下源码包安装Swoole及基本使用操作图文详解

?php
  //创建Server对象，监听 127.0.0.1:9501端口
  $serv = new swoole_server("127.0.0.1", 9501); 
 
  //监听连接进入事件
  $serv->on('connect', function ($serv, $fd) { 
    echo "Client: Connect.\n";
  });
 
  //监听数据接收事件
  $serv->on('receive', function ($serv, $fd, $from_id, $data) {
    $serv->send($fd, "Server: ".$data);
  });
 
  //监听连接关闭事件
  $serv->on('close', function ($serv, $fd) {
    echo "Client: Close.\n";
  });
 
  //启动服务器
  $serv->start(); 

?php
  //创建Client对象，监听 127.0.0.1:9501端口
  $client = new swoole_client(SWOOLE_SOCK_TCP); 

  if(!$client->connect("127.0.0.1" ,9501)){
	echo "连接失败";
	exit;
  }

  //向tcp服务器发送消息
  fwrite(STDOUT, "请输入：");
  $msg = trim(fgets(STDIN));
  $client->send($msg);

  //接受tcp服务器消息
  $result = $client->recv();
  echo $result;

?php
  //创建Server对象，监听 127.0.0.1:9502端口，类型为SWOOLE_SOCK_UDP
  $serv = new swoole_server("127.0.0.1", 9502, SWOOLE_PROCESS, SWOOLE_SOCK_UDP); 

  //监听数据接收事件
  $serv->on('Packet', function ($serv, $data, $clientInfo) {
    $serv->sendto($clientInfo['address'], $clientInfo['port'], "Server ".$data);
    var_dump($clientInfo);
  });

  //启动服务器
  $serv->start(); 

?php
  $http = new swoole_http_server("0.0.0.0", 9501);
  
  //配置静态文件根目录(可选)
  $http->set([
    'document_root' => '/www/wwwroot/lwsblog',
    'enable_static_handler' => true,
  ]);

  $http->on('request', function ($request, $response) {
    var_dump($request->get, $request->post);
    
    //设置header
    $response->header("Content-Type", "text/html; charset=utf-8");

    //设置cookie
    $response->cookie("name", "lws", time()+3600);

    //发送Http响应体，并结束请求处理。
    $response->end("h1>Hello Swoole. #".rand(1000, 9999)."/h1>");
  });

  $http->start();

?php
  //创建websocket服务器对象，监听0.0.0.0:9501端口
  $ws = new swoole_websocket_server("0.0.0.0", 9501);
  
  //配置静态文件根目录(可选)
  $ws ->set([
    'document_root' => '/www/wwwroot/lwsblog',
    'enable_static_handler' => true,
  ]);

  //监听WebSocket连接打开事件
  $ws->on('open', function ($ws, $request) {
    var_dump($request->fd, $request->get, $request->server);
    $ws->push($request->fd, "hello, welcome\n");
  });

  //监听WebSocket消息事件
  $ws->on('message', function ($ws, $frame) {
    echo "Message: {$frame->data}\n";
    $ws->push($frame->fd, "server: {$frame->data}");
  });

  //监听WebSocket连接关闭事件
  $ws->on('close', function ($ws, $fd) {
    echo "client-{$fd} is closed\n";
  });

  $ws->start();
