我正在尝试使用QtWebApp创建一个简单的Web应用程序服务器，但是Chrome，Firefox和Chromium总是两次请求页面
HttpListener: Listening on port 8084
HttpConnectionHandler (0x642770): constructed
HttpConnectionHandler (0x6436e0): constructed
HttpConnectionHandler (0x642770): thread started
HttpConnectionHandler (0x642770): handle new connection
HttpConnectionHandler (0x642770): received request
request start --> with chrome/firefox/chromium
HttpConnectionHandler (0x6436e0): thread started
HttpConnectionHandler (0x6436e0): handle new connection
request end
HttpConnectionHandler (0x642770): received request
request start --> i'm not refreshing the page but this appear
HttpConnectionHandler (0x6436e0): read timeout occured
HttpConnectionHandler (0x6436e0): disconnected
request end
HttpConnectionHandler (0x642770): read timeout occured
HttpConnectionHandler (0x642770): disconnected
HttpConnectionHandler (0x6436e0): thread stopped
HttpConnectionHandler (0x6436e0): destroyed
HttpConnectionHandlerPool: Removed connection handler (0x6436e0), pool size is now 1
HttpConnectionHandler (0x642770): handle new connection
HttpConnectionHandler (0x642770): received request
request start --> when using curl
request end
HttpConnectionHandler (0x642770): disconnected
HttpConnectionHandler (0x6436e0): disconnected
HttpConnectionHandler (0x642770): read timeout occured
HttpConnectionHandler (0x642770): disconnected
HttpConnectionHandler (0x6436e0): thread stopped
HttpConnectionHandler (0x6436e0): destroyed
我对卷发的反应只是：
> GET / HTTP/1.1
> User-Agent: curl/7.35.0
> Host: localhost:8084
> Accept: */*
>
< HTTP/1.1 200 OK
< Content-Type: text/html; charset=ISO-8859-1
< Transfer-Encoding: chunked
<
* Connection #0 to host localhost left intact
<html><body>-4417809641995</body></html>
在" Chrome Developer Tools>网络"选项卡上，它仅要求一次。

这个浏览器的问题还是控制器的类？
正如Florian Sowade在评论中所说的那样，第二个请求是/favicon.ico
