有没有办法通过 Qt WebChannel 使用同步函数调用?

Is there any way to use synchronous function call through Qt WebChannel?

Qt WebKit Bridge 不同,我找不到使用 Qt WebChannelJS side 上使用同步函数调用。

有什么办法吗?

我觉得没办法。文档中说:QWebChannel

Note that all communication between the HTML client and the QML/C++ server is asynchronous.

此外,这篇博客中正是这样说的:Bridge the gap between C++/QML and the web

But, contrary to the WebKit Bridge, the API provided by the WebChannel is completely asynchronous.

希望对您有所帮助。
