SharePoint Server 身份验证错误

Question

所以我之前使用的是托管的 SharePoint 网站，当我使用以下代码对该网站进行身份验证时，一切正常：

private static NetworkCredential credentials = new NetworkCredential(username, password, domain);
private static ClientContext clientContext = new ClientContext("https://thisonesite.com/hosting/151");
private static Web site = clientContext.Web;
private static List list = site.Lists.GetByTitle(listName);

private static void sharepointLogin()
{
    try
    {
       //Loads credentials needed for authentication
       clientContext.Credentials = credentials;
       //Loads the site
       clientContext.Load(site);
       //Loads the site list
       clientContext.Load(list);
       //Executes the previous queries on the server
       clientContext.ExecuteQuery();
       //Writes out the title of the SharePoint site to the console
       Console.WriteLine("Title: {0}", site.Title);
    }
    catch (Exception e)
    {
        Console.WriteLine(e.ToString());
    }
}

现在，我为我创建了一个沙盒，我可以（手动）访问该站点。但是，当我尝试通过我的 c# 代码对站点进行身份验证时，出现错误。

除了用户名、密码和域名，我真正改变的只是private static ClientContext clientContext = new ClientContext("http://sandbox");。

我在控制台中得到的错误是：

System.Net.WebException: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

有谁知道为什么突然在新的 SharePoint 网站上出现此错误？

Answer 1

在每次 executeQuery() 之前都需要一个凭证

你需要两个 executeQuery() 来分别加载站点和列表。

clientContext.Credentials = credentials;
       clientContext.Load(site);
       clientContext.ExecuteQuery();

clientContext.Credentials = credentials;
       clientContext.Load(list);
       clientContext.ExecuteQuery();
