I send a post request to windows local service(c#) at http://127.0.0.1:13728. When i open the website at chrome, my local service can't get request body. Windows service code:
string recData = new StreamReader(request.InputStream).ReadToEnd();
request:
The recData is null or empty. When i open it at ie or other browser, it works fine. The Chrome works fine before. But recently it suddenly doesn't work. I searched a lot , but can't figure out why.
Please help.Thx.
I find out why. Because chrome 98 update, when request a private network, the browser will send a preflight first. But my local service ignore the preflight request and don't return anything. The preflight request status is always pending，so the really request don't send.
