WCF服務的響應不一致
[英]Inconsistent response from the WCF service
問題描述
我有一個IIS7中托管的WCF服務，該服務只是另一個服務的包裝，因此它調用實際的服務，然后返回響應，然后將響應傳遞給客戶端。 我遇到的問題是我發送了一個請求，並返回了數據，當我在第二個請求中發送了另一個請求時，出現以下錯誤：請您就此可能出現的問題分享一些看法。

這是REST服務嗎？ SOAP服務？ 我認為您沒有在服務中處理異常，因此您從IIS（它是一個網頁）獲取默認響應。
您應該在服務中處理異常，並返回包含異常詳細信息的對象（或XML）。
如果是調用錯誤，則應嘗試自定義處理服務上的傳入請求。
也許這可以幫助指定的參數超出有效值范圍。 參數名稱：site
使用DataContractSerializer序列化從WCF服務收到的響應
