WebResponse loginResponse = loginRequest.GetResponse();引发异常.
对于能帮助我了解实际内容的任何建议,我将不胜感激.
I will be grateful for any suggestions to help me get to the actual content.
谢谢.
推荐答案您需要阅读WebException的Response属性,如下所示:
You need to read the WebException's Response property, like this:
WebResponse loginResponse; try { loginResponse = loginRequest.GetResponse(); } catch(WebException ex) { if (ex.Status == WebExceptionStatus.ProtocolError) { loginResponse = ex.Response; } else throw; } //Do something with the response, and remember to dispose it.更多推荐
使用StatusCode 401获取响应的内容
