QWebSocketServer 是 Qt 框架中用于处理 WebSocket 服务器端的类。它允许开发者创建 WebSocket 服务器接受客户端的连接并与之进行双向通信。WebSocket 是一种在单个 TCP 连接上进行全双工通讯的协议它使得客户端和服务器之间的数据交换变得更加简单和高效。
QWebSocketServer 提供了 WebSocket 服务器所需的基本功能包括监听端口、接受连接、发送和接收消息等。它通常与 QWebSocket 类一起使用后者表示一个 WebSocket 连接并提供了与该连接进行交互的方法。 2、重要方法
QWebSocketServer 类的重要方法包括但不限于
QWebSocketServer(const QString serverName, QWebSocketServer::NonSecureMode serverType NonSecureMode, QObject *parent nullptr): 构造函数创建一个 WebSocket 服务器实例。bool listen(const QHostAddress address QHostAddress::Any, quint16 port 0): 使服务器监听指定的地址和端口。void close(): 关闭服务器停止监听连接。QListQWebSocket * clients() const: 返回当前连接到服务器的所有客户端列表。bool hasPendingConnections() const: 检查是否有等待接受的连接。QWebSocket *nextPendingConnection(): 接受一个等待中的连接并返回一个新的 QWebSocket 对象来表示该连接。QString serverName() const: 返回服务器的名称。QWebSocketServer::WebSocketServerState state() const: 返回服务器的当前状态如监听中、关闭等。 3、重要信号
QWebSocketServer 类的重要信号包括
newConnection(): 当有新的客户端连接请求时发出。acceptError(QAbstractSocket::SocketErrors socketError):当连接出现错误时发出信号。serverError(0WebSocketProtocol::CloseCode closeCode):当服务器发生错误时发出信号。 4、常用枚举类型
以下是 QWebSocketServer类中一些常用的枚举类型及其简要介绍QWebSocketServer::SslMode: SSL 模式。
SslMode::NonSecureMode:不支持SSL/TLSSslMode::SecureMode:支持SSL/TLS 5、实现 SSL/TLS 加密 QWebSocketServer 支持 SSL/TLS 加密以提供安全的WebSocket 连接。为了实现SSL/TLS您需要配置合适的证书和密钥 QWebSocketServer server(Secure WebSocket Server, QWebSocketServer::SecureMode); QSslConfiguration sslConfiguration; sslConfiguration.setLocalCertificate(QStringLiteral(server.crt)); sslConfiguration.setPrivateKey(QStringLiteral(server.key)); server.setSslConfiguration(sslConfiguration); if (server.listen(QHostAddress::Any, 1234)) { qDebug() Secure WebSocket server listening on port 1234.; } //.h
