c# - 使用 SharePoint Web 服务进行身份验证

Question

我正在尝试从 asp.net 应用程序调用 GetListItems。

System.Net.NetworkCredential userDefined = new System.Net.NetworkCredential("username","password","domain");
XmlDocument xmlDoc = new System.Xml.XmlDocument();
XmlNode ndQuery = xmlDoc.CreateNode(XmlNodeType.Element, "Query", "");
XmlNode ndViewFields = xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "");
XmlNode ndQueryOptions = xmlDoc.CreateNode(XmlNodeType.Element, "QueryOptions", "");
ndQueryOptions.InnerXml = "";
ndViewFields.InnerXml = "";

WebReference.Lists lists = new WebReference.Lists();

lists.Credentials = userDefined;
XmlNode responseNode = lists.GetListItems("My List Name", null, ndQuery, ndViewFields, null, ndQueryOptions, null);

我收到一个错误:

the request failed with http status 401 unauthorized

我搜索了 SO 并尝试了我发现的内容:

WebReference.UseDefaultCredentials = true;

和

WebReference.Credentials = System.Net.CredentialCache.DefaultCredentials;

和

<identity impersonate="true"  userName="mydomain\username" password="password" />

我尝试过的所有方法都得到了相同的错误消息。有人知道我可能遗漏了什么吗？

如果您的共享点使用浏览器身份验证，您需要预授权

svc.PreAuthenticate = true;
svc.Credentials = new System.Net.NetworkCredential(username, password);

如果它的形式是 auth，或者除 NTLM 之外的任何其他形式，那么就会更加困惑 - 尽管到目前为止，我总是以 403 响应
