Question

我的应用程序的以下部分存在问题，它返回错误403作为HttpWebRequest的响应。你能告诉我为什么会出现这个错误吗？

                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，当我使用以下命令在powerShell中发送相同的请求时，我得到了成功响应：

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

对不起，如果这没有提示答案;我不会让我发表评论。

您确定webServiceServerName + uri评估的价值为a.k.a.＆＃34; APIURL.Domanin.com＆＃34;？也许该代码巧合地试图与服务器进行通信，而该服务器不是您之后的服务器，它具有另一组认证/授权规则（HTTP-403表示＆＃34;禁止＆＃34;）

C＃HttpWebRequest返回错误403
