远程服务器返回错误：（401）未经授权。

我邮箱的凭证是正确的！

HttpWebRequest request =

                WebRequest.Create("https://www.contoso.com/ews/exchange.asmx/s/GetUserPhoto?email=sadie@contoso.com&size=HR240x240";)

                as HttpWebRequest;

                CredentialCache cc = new CredentialCache();

                cc.Add(

                new Uri("https://www.contoso.com/ews/exchange.asmx/s/GetUserPhoto?email=sadie@contoso.com&size=HR240x240";), 

                "NTLM", 

                new NetworkCredential("domainusername", "Mypass"));

                request.Credentials = cc;

                         request.Credentials =cc;

                // Submit the request.

                using (HttpWebResponse resp = request.GetResponse() as HttpWebResponse)

                {

                    // Take the response and save it as an image.

                    Bitmap image = new Bitmap(resp.GetResponseStream());

                    image.Save("Sadie.jpg");

                }

        

Answer 1

如果你尝试怎么办？

new NetworkCredential("username", "password", "domain")

确保URI是正确的（不是www.contoso.com ）。
