利用workerman和HTML5 WebSocket技术实现实时在线聊天

Using Workerman and HTML5 WebSocket technology to achieve real-time online chat

Introduction:
With the rapid development of the Internet and the popularity of smartphones, real-time online chat has become an integral part of people's daily lives. In order to meet the needs of users, web developers are constantly looking for more efficient and real-time chat solutions. This article will introduce how to combine the PHP framework Workerman and HTML5 WebSocket technology to implement a simple real-time online chat system.

1. Introduction to Workerman:
Workerman is a PHP developer-friendly high-performance asynchronous IO framework that can implement high-performance TCP/UDP real-time communication applications. Compared with the traditional PHP development method, Workerman has higher concurrency capabilities and lower resource consumption, and is very suitable for implementing real-time online chat systems.

2. Introduction to HTML5 WebSocket:
WebSocket is a full-duplex communication protocol based on the TCP protocol, which can establish a persistent connection between the client and the server to achieve real-time data transmission. The newly added WebSocket technology in HTML5 has very important application value in real-time chat and other real-time data transmission.

3. Environment preparation:

  1. Server operating system: linux
  2. PHP version: 7.0 and above
  3. Install Workerman:

    $ composer require workerman/workerman

4. Server-side implementation:

  1. Create chat.php file and write server-side code:

    <?php 
    require_once __DIR__.'/vendor/autoload.php'; // 加载Workerman的自动加载文件
    
    use WorkermanWorker;
    
    // 创建一个Worker监听2346端口,使用WebSocket协议通讯
    $ws_worker = new Worker("websocket://0.0.0.0:2346");
    
    $ws_worker->count = 4; // 设置进程数
    
    // 客户端与服务器建立连接时触发
    $ws_worker->onConnect = function($connection){
     echo "Connection established: " . $connection->id . "
    ";
    };
    
    // 客户端向服务器发送消息时触发
    $ws_worker->onMessage = function($connection, $data){
     echo "Received message: " . $data . "
    ";
    
     // 向所有在线用户发送消息
     foreach($connection->worker->connections as $clientConnection){
         $clientConnection->send($data);
     }
    };
    
    // 客户端断开连接时触发
    $ws_worker->onClose = function($connection){
     echo "Connection closed: " . $connection->id . "
    ";
    };
    
    Worker::runAll();
  2. Start the WebSocket service:

    $ php chat.php start

5. Client implementation:

  1. Create the chat.html file and write the client code:

    <!DOCTYPE html>
    <html>
    <head>
     <title>实时在线聊天</title>
     <script>
         var ws = new WebSocket("ws://localhost:2346");
    
         ws.onopen = function(event){
             console.log("Connected to WebSocket server.");
         };
    
         ws.onmessage = function(event){
             var message = event.data;
             console.log("Received message: " + message);
             
             // 在页面上显示接收到的消息
             var messageBox = document.getElementById("message-box");
             var newMessage = document.createElement("p");
             newMessage.innerText = message;
             messageBox.appendChild(newMessage);
         };
    
         function sendMessage(){
             var message = document.getElementById("message-input").value;
             ws.send(message);
             document.getElementById("message-input").value = "";
         }
     </script>
    </head>
    <body>
     <div id="message-box"></div>
     <input id="message-input" type="text" placeholder="输入消息">
     <button onclick="sendMessage()">发送</button>
    </body>
    </html>
  2. Use a browser to open the chat.html file to start real-time online chat.

6. Summary:
This article introduces how to use Workerman and HTML5 WebSocket technology to achieve real-time online chat. By using the high-performance Workerman framework and the two-way communication capabilities of WebSocket, we can easily implement a simple online chat system. In addition to the chat system, we can also use WebSocket technology to implement more real-time communication applications, such as real-time games, real-time stock quotes, etc. I hope this article will be helpful for developing real-time online chat systems and inspire more ideas and applications.
