C＃HttpWebRequest返回錯誤403

Question

我的應用程序的以下部分有問題，該錯誤返回403作為HttpWebRequest的響應。 您能否讓我知道為什么會出現此錯誤？

                string url = "http://" + webServiceServerName + uri + "?extendedInfo=2";
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
                request.ContentType = "application/json";

                //Failed tries to fix this error 403, non of these fix the issue
                request.UserAgent = "[AnyWordThatIsMoreThan5Char]";
                request.UseDefaultCredentials = true;
                request.Accept = "*/*";


                //Get the headers associated with the request.
                WebHeaderCollection myWebHeaderCollection = request.Headers;
                //Add Custom header fields
                myWebHeaderCollection.Add("api-version","1.0");
                myWebHeaderCollection.Add("auth-key","XYZ");


                // Gets the stream associated with the response.            
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                // response contains error 403 

但是，當我使用以下命令在powerShell中發送相同的請求時，會收到成功響應：

> $headers = @{"api-version"="1.0"; "auth-key"="XYZ"}
> Invoke-RestMethod -Uri "http://APIURL.Domanin.com?extendedinfo=2" -Headers $header -ContentType "application/json" -Method Get

Answer 1

很抱歉，如果這不能提示答案； 所以我不會發表評論。

您確定webServiceServerName + uri的值等於“ APIURL.Domanin.com”嗎？ 也許該代碼巧合地最終試圖與服務器通信，而不是您所追求的服務器，該服務器具有另一組身份驗證/授權規則（HTTP-403表示“禁止”）。
