請求，HTTP狀態401失敗：授權從C＃asp.net訪問SharePoint Web服務

我打了以下錯誤：請求，HTTP狀態401失敗：授權從C＃asp.net訪問SharePoint Web服務

The request failed with HTTP status 401: Unauthorized.

守則

的代碼如下：

protected void Execute_Click(object sender, EventArgs e) 
    { 



     /*Declare and initialize a variable for the Lists Web service.*/ 
     //Web_Reference.Lists myservice = new Web_Reference.Lists(); 
     ListsWebService.Lists myservice = new ListsWebService.Lists(); 

     /*Authenticate the current user by passing their default 
     credentials to the Web service from the system credential 
     cache. */ 
     myservice.Credentials = 
      System.Net.CredentialCache.DefaultCredentials; 

     /*Set the Url property of the service for the path to a subsite. Not setting this property will return the lists in the root Web site.*/ 
     //listService.Url = "http://Server_Name/Subsite_Name/_vti_bin/Lists.asmx"; 
     myservice.Url = "http://teamsites.ntu.edu.sg/sce/hrdev/_vti_bin/Lists.asmx"; 

     try 
     { 
      /*Declare an XmlNode object and initialize it with the XML 
      response from the GetListCollection method. */ 
      System.Xml.XmlNode node = myservice.GetListCollection(); 

      /*Loop through XML response and parse out the value of the 
      Title attribute for each list. */ 
      foreach (System.Xml.XmlNode xmlnode in node) 
      { 
       Label1.Text += xmlnode.Attributes["Title"].Value + "\n"; 
      } 
     } 
     catch (Exception excep) 
     { 
      Label1.Text = excep.Message; 
     } 


    }

IIS設置 - 僅啓用Windows身份驗證。

如果我能會丟失？

看起來像您使用WCF服務一樣添加服務引用。您應該爲asmx服務添加「添加Web服務引用」。 – Flowerking

@Flowerking，是的，我已經將它添加爲「添加Web服務引用」。 – Jack

正如你只有「Windows身份驗證」服務器端啓用，嘗試改變，如下配置：

<security mode="TransportCredentialOnly"> 
     <transport clientCredentialType="Ntlm" proxyCredentialType="None" 
       realm="" />

不，我改變配置，但仍然無法得到它的工作。 – Jack

看着你的配置，我發誓你引用了列表服務兩次。一個是wcf引用，另一個是web引用？如果是這樣，擺脫wcf參考並重建解決方案再試一次。 – Flowerking

是您的C＃ASP.NET同一物理服務器的SharePoint上運行？

如果是的話那麼它的一個很好的機會，其"Local Loopback Check"

如果你的ASP.Net頁面是在同一個局域網可以使用System.Net.CredentialCache方法。請參閱參考：http://msdn.microsoft.com/en-us/library/hh134614(v=office.14).aspx

如果您的ASP.Net頁面未託管在同一個Intranet中，則需要越過Sharepoint站點的身份驗證提供程序。請參閱參考：http://msdn.microsoft.com/en-us/library/hh147177(v=office.14).aspx
