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();

虽然我提供的凭据是正确的，但我收到了响应“401：未经授权”。我在这里错过了什么？

Answer 1

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