Debugging the front-end page, the endpoint is invalid, I need a better solution

I used in Qt project QtWebEngine module, front end developers hope to open in a browser / / 127.0.0.1:1112 debug on the front page, in the process of Qt program is running, the front-end developers set breakpoints effectively in chrome, but Qt program shut down and restart again, front of JS code is one of the endpoints, there is no front debugging very inconvenient.

qputenv("QTWEBENGINE_REMOTE_DEBUGGING", "1112");
