在AJAX Web應用程序中發送JSON幫助WCF servcie

我想設置一個ASPX頁面來調用一個ScriptManager的WCF服務。由於某種原因，當我調用servcie的「SpinStitch.Services.Chat.IChatter.CreateChatSession」方法時，出現此錯誤「服務器方法'CreateChatSession'失敗。'我在服務器的CreateChatSession方法中設置了一個斷點，但是它從來沒有達到過這樣的程度，我不確定我設置錯了什麼，我已經看了100個樣本，如何設置它們，它們看起來都差不多。僅僅指剛諾埃的<％= ChatSessionObject％> 屬性是從後面的ASPX代碼來，並創建一個JSON序列化對象。有什麼想法？在AJAX Web應用程序中發送JSON幫助WCF servcie

     [OperationContract] 
     bool CreateChatSession(Domain.Objects.ChatSession chat); 

    } 

}

     public bool CreateChatSession(Domain.Objects.ChatSession chat) 
     { 
      return ChatSessionAdapter.CreateChatSession(chat) > 0; 
     } 
    }

因爲服務在單獨運行主要。在.Net 3.5下，你無法跨域。感謝大家的期待！

它看起來並不像ChatSession是DataContract /數據成員的對象。相反，它看起來像某種純粹的腳本對象，對嗎？如果是這樣，那很可能是操作失敗的原因。

實際上，它失敗了，因爲服務運行在一個單獨的域中，並且這是3.5中的No-No現在，在4.0中，您可以跨域。我會發布這個答案。 – DDiVita 2011-02-03 11:47:28
