在asp.net C#中使用客户端ID和客户端密码访问Sharepoint列表

Question

目前，我可以使用下面给出的用户 ID 和密码访问共享点列表。但想了解如何使用客户端 ID 和客户端密码访问列表？

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 内核的GetAppOnlyAuthenticatedContext 方法。

之后就可以使用下面的代码了：

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，请转到您的项目参考 > 管理 nuget 包。

添加 SharePointPnPCoreOnline 包。

Expose on public web your SharePoint Online information

Answer 2

SharePointPnPCoreOnline已经退役，如果您的项目目标框架是.Net Core，安装它会导致库冲突问题。

这是经过测试并适用于 .Net Core 的代码。

后继 Nuget 包名称：PnP.Framework

命名空间：

using PnP.Framework;  
using Microsoft.SharePoint.Client;

示例代码：

    string siteUrl = "https://xyz.sharepoint.com/sites/MySubSite" ;
    string ClientSecret = "<client-secret>";
    string ClientId = "<client-id>";


    using (var clientContext = new AuthenticationManager().GetACSAppOnlyContext(siteUrl, ClientId, ClientSecret))
    {
        Web oWebsite = clientContext.Web;
        ListCollection collList = oWebsite.Lists;
        clientContext.Load(collList);
        clientContext.ExecuteQuery();
        string result = "Total SP Library count is " + collList.Count();

    }
