c++ - 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

LoadURL由于 Chromium 的异步特性，无法保证在浏览器即将关闭时发出请求会成功。

我建议您为此目的使用另一个库，它可以是：

• libcurl（包裹在 curlpp 中）
• 插座

你必须在里面发出你的 HTTP 请求

void OnBeforeClose(CefRefPtr<CefBrowser> browser);

方法，您必须在子类化SimpleHandler并CefLifeSpanHandler添加后实现

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