连接到Sharepoint Online返回401：未经授权

Question

我正在尝试使用C＃API执行Sharepoint Online搜索：

var clientContext =
    new ClientContext("https://foobar.sharepoint.com/_layouts/15/start.aspx#/Shared%20Documents");
var pw = "apassword";
var secure = new SecureString();
foreach (var c in pw) secure.AppendChar(c);

var credentials = new SharePointOnlineCredentials("adress@mail.com", secure);
clientContext.Credentials = credentials;

var keywordQuery = new KeywordQuery(clientContext);
keywordQuery.QueryText = "SharePoint";
var searchExecutor = new SearchExecutor(clientContext);
var results = searchExecutor.ExecuteQuery(keywordQuery);
clientContext.ExecuteQuery();

我得到了回复＆＃39; 401：未经授权＆＃39;尽管我提供的凭据是正确的。我在这里缺少什么？

Answer 1

您正在尝试连接到SharePoint文档库（https://foobar.sharepoint.com/_layouts/15/start.aspx#/Shared%20Documents）。尝试连接“https://foobar.sharepoint.com/”。

此外，客户端上下文可能没有足够的权限来执行搜索。
