WCF REST服務返回錯誤：遠程服務器返回錯誤：（400）錯誤的請求

Question

我已經從以下項目中致電Rest WCF Service

 userAlias = "test";
                var url = new StringBuilder();
                url.Append(
                    string.Format("https://webdemo-t.orioninc.com:8443/Services/2012v2/TestService.svc/AddAttachment?User={0}&Engagement={1}&FileName={2}&DocumentTrasferID={3}&fileSize={4}&ActivityName={5}",userAlias, engagementName, fileName, documentTranferId, fileSize, activityName));
                WebRequest request = WebRequest.Create(url.ToString());
                CurrentUrl = url.ToString();
                var networkCredential = new NetworkCredential("jame", "test", "company");
                request.Credentials = networkCredential;
                WebResponse response = request.GetResponse();
                Encoding encoding = Encoding.GetEncoding(1252);
                var responseStream = new StreamReader(response.GetResponseStream());
                string responseResult = responseStream.ReadToEnd();
                responseStream.Close();
                Console.WriteLine(responseResult);

調用這些服務時，我得到了異常遠程服務器返回錯誤：（400）錯誤的請求。 當我嘗試在WCH實現方法中返回普通字符串時，我正確地獲得了webresponse結果。如何解決此錯誤？

WCF實施方法

  public string AddAttachment(string User, string Engagement, string FileName, string DocumentTrasferID, string fileSize, string ActivityName)
    {
        dynamic _Trackerfaccade = new KPMG.EauditEmailService.Facade.EAppEmail();
        string Result = _Trackerfaccade.AddAttachment(User, Engagement, FileName, DocumentTrasferID, fileSize, FileName);
        return Result;
    }

經營合同

     [OperationContract]

   [WebGet(UriTemplate = "/AddAttachment?User={userAlias}&Engagement={engagementName}&FileName={FileName}&DocumentTrasferID={documentTranferId}&fileSize={fileSize}&activityName={activityName}", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
    string AddAttachment(string userAlias, string engagementName, string documentTranferId,string fileName,string fileSize,string activityName);

Answer 1

"/AddAttachment?User={0}&Engagement={1}&FileName={2}&DocumentTrasferID={3}&fileSize={4}&ActivityName={5}"

"/AddAttachment?userAlias={userAlias}&engagementName={engagementName}&documentTranferId={documentTranferId}&fileName={fileExtension}&fileSize={fileSize}&activityName={activityName}"
