详细说明
QWebChannel 的用户必须实现该接口，并为每个应连接到QWebChannel 的客户端将其实例连接到QWebChannel 服务器。Qt WebChannel 独立示例展示了如何使用 Qt WebSockets.
注： JSON 消息协议被视为内部协议，可能会随时间推移而改变。

成员函数文档
[explicit] QWebChannelAbstractTransport::QWebChannelAbstractTransport(QObject *parent = nullptr)
用给定的parent 构建一个传输对象。
[override virtual noexcept] QWebChannelAbstractTransport::~QWebChannelAbstractTransport()
销毁传输对象。
[signal] void QWebChannelAbstractTransport::messageReceived(const QJsonObject &message, QWebChannelAbstractTransport *transport)
从远程客户端接收到新的 JSONmessage 时，必须发出该信号。transport 参数应设置为该传输对象。
[pure virtual slot] void QWebChannelAbstractTransport::sendMessage(const QJsonObject &message)
向远程客户端发送 JSONmessage 。实现方法是将信息序列化，然后将其发送到远程 JavaScript 客户端。
