Office365用戶查詢返回的照片作爲空

Question

試圖檢索使用Microsoft.Graph庫上的域用戶的列表：

GraphServiceClient graphClient = SDKHelper.GetAuthenticatedClient(); 
var request = graphClient.Users.Request().Select("businessPhones, displayName, givenName, id, jobTitle, mail, mobilePhone, officeLocation, preferredLanguage, surname, userPrincipalName, photo"); 
var ListOfUsers = await request.GetAsync(); 

並且範圍：

Scope = "openid email profile offline_access User.Read User.ReadWrite User.ReadBasic.All " + graphScopes, 

照片字段始終空值。什麼是爲所有用戶檢索照片的正確方法？

Answer 1

有一個單獨的端點，以獲取照片的用戶

graphClient.Users[<UserPrincipalName>].Photo.Content.Request()
