Sharepoint REST API和MVC AAD连接(Sharepoint REST api and MVC AAD connect)

 我的需求是通过C＃中的服务器端执行此查询https://<tenant>.sharepoint.com/_api/search/query?querytext=%27contenttype:articles%27通过Sharepoint REST api。 
 
 我有来自MVC门户的Oauth2连接，所以我的目标是从连接中检索令牌并将其作为持票人令牌发送到共​​享点端点。 
 
 我的意思是这样的 
 
  string userObjectID = ClaimsPrincipal.Current.FindFirst("http://schemas.microsoft.com/identity/claims/objectidentifier").Value;
  AuthenticationContext authContext = new AuthenticationContext(Startup.Authority, new NaiveSessionCache(userObjectID));
  ClientCredential credential = new ClientCredential(clientId, appKey);
  AuthenticationResult result = await authContext.AcquireTokenSilentAsync("https://<tenant>.sharepoint.com/", credential, new UserIdentifier(userObjectID, UserIdentifierType.UniqueId));

  HttpClient client = new HttpClient();
  HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "https://<tenant>.sharepoint.com/_api/search/query?querytext=%27contenttype:articles%27");
  request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken);
  HttpResponseMessage response = await client.SendAsync(request);
 
 但显然，我无法检索令牌... 
 
 另一方面，我用ADv2和GraphServiceClient构建了一个运行良好的应用程序，但我不知道如何在图模型中转换查询（并且我没有任何管理员同意）。 
 
 所以，我有两种方法可以解决我的问题，我希望更好地使用Microsoft图形API的第二个选项，但是欢迎任何帮助。 
 
 谢谢。 

My need is to execute this query https://<tenant>.sharepoint.com/_api/search/query?querytext=%27contenttype:articles%27 thru Sharepoint REST api from server side in C#.
 
I have Oauth2 connection from the MVC portal, so my goal is to retrieve token from connection and send it as bearer token to sharepoint endpoint.
 
I mean something like that 
 
  string userObjectID = ClaimsPrincipal.Current.FindFirst("http://schemas.microsoft.com/identity/claims/objectidentifier").Value;
  AuthenticationContext authContext = new AuthenticationContext(Startup.Authority, new NaiveSessionCache(userObjectID));
  ClientCredential credential = new ClientCredential(clientId, appKey);
  AuthenticationResult result = await authContext.AcquireTokenSilentAsync("https://<tenant>.sharepoint.com/", credential, new UserIdentifier(userObjectID, UserIdentifierType.UniqueId));

  HttpClient client = new HttpClient();
  HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "https://<tenant>.sharepoint.com/_api/search/query?querytext=%27contenttype:articles%27");
  request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken);
  HttpResponseMessage response = await client.SendAsync(request);
 
but obviously, I can not retrieve the token...
 
On another side, I have built an app with ADv2 and GraphServiceClient that is working well, but I don't know how to translate the query in graph model (and I don't have any admin-consent).
 
So, I have 2 ways to resolve my issue, I'll like better use the 2nd option with microsoft graph api, but any help is welcome.
 
Thank you.
