远程服务器返回错误：(401) Unauthorized in context.ExecuteQuery() : ASP.Net

Question

我正在使用以下代码 sn-p 连接共享点服务器 API。正如预期的那样，这个 sn-p 在空白项目中运行良好。它返回列表公告、共享文档、任务...等。

但是当我将它与现有应用程序集成时，它会在 context.ExecuteQuery() 中抛出 The remote server returned an error: (401) Unauthorized 错误消息。

我尝试提供返回相同错误的Context.Credentials = new NetworkCredential( username, password, domain );。

代码：

using (ClientContext context = new ClientContext(ServerUrl))
{
    //get all the lists from sharepoint
    //all the files and folders resides inside some list.
    Web web = context.Web;
    context.Load(web.Lists, its => its.Include(it => it.Title, it => it.Id, it => it.RootFolder.ServerRelativeUrl));

    context.ExecuteQuery();
    foreach (var list in web.Lists)
    {
        //add all the lists to treeview
        //list id is assigned to node value and list's server relative url is assigned to tooltip
        tvItems.Nodes.Add(new Telerik.Web.UI.RadTreeNode
        {
            Value = list.Id.ToString(),
            Text = list.Title,
            ExpandMode = Telerik.Web.UI.TreeNodeExpandMode.ServerSide,
            ToolTip = list.RootFolder.ServerRelativeUrl
        });
    }
}

我尝试将 context.Load(web.Lists, its => its.Include(...); 代码行更改为 context.Load(web.Lists, its => ClientObjectQueryableExtension.Include(...)); 以确保共享点引用不会与现有的一次混合。

任何帮助都会很好地解决这个问题。

如果您想从提供商托管的应用程序中访问上下文，您可以使用以下内容：

        var spContext = SharePointContextProvider.Current.GetSharePointContext(HttpContext);
        using (var clientContext = spContext.CreateUserClientContextForSPHost())
        { 
          .... 
        }
