HttpWebRequest returns Badrequest (400) and returns response

Today when using Fiddler to analyze a login feature of the Android app, the account and password errors return the corresponding message, and the status code is 400.

Normal usage:

1         /// <summary>2         ///read the returned content3         /// </summary>4         /// <param name= "asyncresult" ></param>5         Private voidreadcallback (IAsyncResult asyncresult)6         {7String result =String.Empty;8             Try9             {TenHttpWebRequest Myrequest =(HttpWebRequest) asyncresult. asyncstate; OneHttpWebResponse response =(HttpWebResponse) myrequest. EndGetResponse (asyncresult); A  -                 //read returned object -Stream Responsestream =Response. GetResponseStream (); the  -                 using(varRender =NewStreamReader (Responsestream, Encoding.UTF8)) -                 { -result =render. ReadToEnd (); + render. Close (); -                 } +             } A             Catch(Exception ex) at             { -  -Console.WriteLine ("An exception occurred:"+Ex. Message); -             } -             //Handling Return Messages -             if(Handler! =NULL) in Handler (result); -}

When execution GetResponseStream throws an exception, the exception hint is badrequest.

To get 400 of the information returned, you need to do special handling of the catch section.

To add a catch code:

1                 using(WebResponse response =e.response)2                 {3HttpWebResponse HttpResponse =(HttpWebResponse) response;4                     using(Stream data =Response. GetResponseStream ())5                     using(varReader =NewStreamReader (data))6                     {7                         stringText =Reader. ReadToEnd ();8 Console.WriteLine (text);9                     }Ten}

This will get the message returned to 400.
