Sharepoint 2010 Web服務GetListItems錯誤400錯誤請求

Question

我寫了一些代碼以從遠程共享點列表中獲取項目。在獨立的Windows窗體應用程序中，它工作正常。但是，真正的任務是將其添加到現有的WCF Web服務中。與引用完全相同的網絡服務的網址完全相同的代碼拋出這個錯誤在事件查看器：

Exception: Exception caught: 'System.Net.WebException' in System.dll ("The remote server returned an error: (400) Bad Request."). Exception caught: 'System.Net.WebException' in System.dll ("The remote server returned an error: (400) Bad Request.")

這發生在這行代碼：

XmlNode nodeListItems = 
         listService.GetListItems 
         (listName, string.Empty, query, viewFields, "0", queryOptions, null); 

我會包括整個方法（用）一些名字改變，以保護無辜:)）。請記住，它在一個獨立的贏取應用程序中工作正常。只有在WCF服務中，這是一個問題。對我來說更奇怪的是它掛起。只有在事件查看器中我看到這個錯誤。我有一個嘗試，我會認爲它會去抓。我甚至增加了一個額外的嘗試，只是爲了看和沒有骰子。這不是網址。這不是憑證。我甚至用硬編碼來確保這一點。也許WCF中有一些隱藏的配置設置？

任何幫助表示讚賞。下面的代碼：

我發現我意外地僅載入rtFa和FedAuth餅乾，但不能從成功登入裝餅乾的其餘部分。這是事實證明，導致我所描述的錯誤。獲取會話中的所有cookie可以解決問題。
