使用asp.net C＃中的客户端ID和客户端密钥访问Sharepoint列表

Question

目前，我可以使用下面给出的用户ID和密码访问sharepoint列表。但是想了解我如何使用客户端ID和客户端密钥访问列表？

string siteUrl = "https://xyz.sharepoint.com/sites/MyList/";
ClientContext clientContext = new ClientContext(siteUrl);
string username = ConfigurationManager.AppSettings["username"];
string password = ConfigurationManager.AppSettings["password"];
System.Security.SecureString passWord = new System.Security.SecureString();
foreach (char c in password.ToCharArray()) 
{    
    passWord.AppendChar(c);
}

clientContext.Credentials = new SharePointOnlineCredentials(username, passWord);
Web oWebsite = clientContext.Web;
ListCollection collList = oWebsite.Lists;
clientContext.Load(collList);
clientContext.ExecuteQuery();

Answer 1

您可以使用PnP CSOM核心的GetAppOnlyAuthenticatedContext方法。

之后您可以使用以下代码：

string siteUrl = "https://xyz.sharepoint.com/sites/MyList/";
string clientId = "<client-id>";
string clientSecret = "<client-secret>";

using (var clientContext = new AuthenticationManager().GetAppOnlyAuthenticatedContext(siteUrl,clientId,clientSecret))
{       
    Web oWebsite = clientContext.Web;
    ListCollection collList = oWebsite.Lists;
    clientContext.Load(collList);
    clientContext.ExecuteQuery();
}

要添加PnP CSOM核心，请转到项目参考＆gt;管理nuget包。

添加SharePointPnPCoreOnline包。
