如何设置httpclient连接超时？

Question

I'm struggling with setting connect timeout with c# HttpClient or its siblings ( HttpClientHandler , WebRequestHandler ,...) . There's a timeout property in HttpClient , but it seems to be a timeout from the beginning of the request until receiving the response. I want to have a method which specify that for example if you don't received ACK from the net socket within 10 seconds for example , then break up and do the next. I saw that there may be something similar in WinHttpHandler class, but it seems to be deleted or not available in recent version. compare the first link vs second :

1. WinHttpHandler MSDN

2. WinHttpHandler Microsoft Docs

I really need this, because I must differentiate asap between IP's which have a working web servers (maybe slow) vs which don't have a web server at all.

Answer 1

I use HttpWebRequest.Timeout in my project to verdict the connection time before establish tcp connection. And use HttpWebRequest.ReadOrWriteTimeout to verdict whole response timeout. Ps: The HttpClient seems cut off some useful properties.
