CEF framework sending http request before close

Question

I want to shut down server on window close (CEFsimple close) by sending http request to localhost:5000/shutdown. I belive this should do the job

 browser->GetMainFrame()->LoadURL("http://127.0.0.1:5000/shutdown/");

So, where is the right place to do that? I have tried with functions like DoClose() and OnBeforeClose()...

Answer 1

Making a LoadURL request when the browser is about to close is not guaranteed to succeed, due to the asynchronous nature of Chromium.

I would suggest you to use another library just for that purpose, which can be:

• libcurl (wrapped in curlpp)
• sockets

You have to make your HTTP request inside

void OnBeforeClose(CefRefPtr<CefBrowser> browser);

method, which you have to implement after subclassing SimpleHandler from CefLifeSpanHandler and adding also

CefRefPtr<CefLifeSpanHandler> SimpleHandler::GetLifeSpanHandler() { return this; }
