Obsolete Members for QWebSocket

QWebSocket 类的以下成员已被废弃。提供这些成员是为了确保旧源代码能够继续运行。我们强烈建议不要在新代码中使用它们。

信号

(deprecated in 6.5) void error(QAbstractSocket::SocketError error)

成员函数文档

[signal, deprecated in 6.5] void QWebSocket::error(QAbstractSocket::SocketError error)

自 6.5 版起，此函数已弃用。我们强烈建议不要在新代码中使用它。

请改用 `errorOccurred`（`QAbstractSocket::SocketError ` 错误）。

注意：此 信号已被重载。要连接到此信号： 

// Connect using qOverload:
connect(webSocket, qOverload(&QWebSocket::error),
        receiver, &ReceiverClass::slot);

// Or using a lambda:
connect(webSocket, qOverload(&QWebSocket::error),
        this, [](QAbstractSocket::SocketError error) { /* handle error */ });
有关更多示例和方法，请参阅“连接到重载信号”。
