使用QT进行websocket 客户端和服务端通讯示例
Qt WebSocket是一个用于构建WebSocket服务器和客户端的模块,它允许在Qt应用程序中轻松地处理WebSocket通信。WebSocket是一种在单个TCP连接上进行全双工通信的协议,常用于实时应用如在线聊天、游戏和API推送。
**服务器端**:
在Qt中,你可以使用QWebSockets类来创建一个WebSocket服务器。首先,你需要设置监听地址,然后处理来自客户端的消息请求,发送响应,并管理连接的生命周期。例如:
```cpp
QWebSocketServer *server = new QWebSocketServer("MyWebSocket", QWebSocketServer::ServerMode);
if (server->listen(QHostAddress::Any, 8080)) {
qDebug() << "WebSocket server is running on port 8080";
} else {
qDebug() << "Failed to start server.";
}
for (;;) {
QWebSocket *socket = server->nextPendingConnection();
if (!socket) break;
// Handle incoming connections...
connect(socket, &QWebSocket::textMessageReceived, this, &YourClass::handleTextMessage);
}
```
**客户端**:
客户端则需要建立到服务器的连接并发送接收消息,例如:
```cpp
QWebSocket *client = new QWebSocket("ws://localhost:8080");
connect(client, &QWebSocket::open, this, &YourClass::onConnected);
connect(client, &QWebSocket::textMessageReceived, this, &YourClass::onMessageReceived);
client->open();
// Send messages...
QString message = "Hello Server!";
client->sendTextMessage(message);
// ...and handle events like close(), error(), etc.
