Microsoft Graph - Memberof 字段为空

Question

我试图在 C# 中获取用户所属的组。为此，我一直在使用 /memberOf 端点，如下所示：

public async Task<IUserMemberOfCollectionWithReferencesPage> Test()
{
    var graphClient = GetGraphClient(config);

    return await graphClient
        .Users["user@contoso.com"]
        .MemberOf
        .Request()
        .GetAsync();
}

获取图形客户端函数是：

public static GraphServiceClient GetGraphClient(Config config)
{
    var graphClient = new GraphServiceClient(new DelegateAuthenticationProvider((requestMessage) =>
    {

        // get an access token for Graph
        var accessToken = GetAccessToken(config).Result;

        requestMessage
            .Headers
            .Authorization = new AuthenticationHeaderValue("bearer", accessToken);

        return Task.FromResult(0);
    }));

    return graphClient;
}

问题是响应只是：

[
{
   "deletedDateTime":null,
   "id":"48215c29-5442-4fbe-b6b4-ce3e1b09157a",
   "oDataType":"#microsoft.graph.group",
   "additionalData":{
      "deletedDateTime":null,
      "classification":null,
      "createdDateTime":null,
      "creationOptions":[

      ],
      "description":null,
      "displayName":null,
      "expirationDateTime":null,
      "isAssignableToRole":null,
      "mail":null,
      "mailEnabled":null,
      "mailNickname":null,
      "membershipRule":null,
      "membershipRuleProcessingState":null,
      "onPremisesDomainName":null,
      "onPremisesLastSyncDateTime":null,
      "onPremisesNetBiosName":null,
      "onPremisesSamAccountName":null,
      "onPremisesSecurityIdentifier":null,
      "onPremisesSyncEnabled":null,
      "preferredDataLocation":null,
      "preferredLanguage":null,
      "renewedDateTime":null,
      "resourceBehaviorOptions":[

      ],
      "resourceProvisioningOptions":[

      ],
      "securityEnabled":null,
      "securityIdentifier":null,
      "theme":null,
      "visibility":null
   }
}
]

该应用拥有以下权限：

Directory.AccessAsUser.All
User.Read.All
User.ReadWrite.All
UserAuthenticationMethod.Read.All
UserAuthenticationMethod.ReadWrite.All
Directory.Read.All
Directory.ReadWrite.All
Group.Read.All
GroupMember.Read.All
User.Read

我使用的所有其他端点、增量、用户、订阅都按预期工作，但由于未知原因，它们与 /memberOf 为空。我真的希望你们能帮助我，我做错了什么，因为我已经用头撞墙太久了:)。

提前致谢。

要获取用户 MemberOf，请在下面的示例中使用下面的查询

 var result = await graphClient.Users[upn].MemberOf .Request() .GetAsync();

使用页面迭代器获取所有目录对象

protected async Task<List<T>> GetAllPagesAsType<T>(
                GraphServiceClient graphClient,
                ICollectionPage<DirectoryObject> page) where T : class
            {
                var allItems = new List<T>();
    
                var pageIterator = PageIterator<DirectoryObject>.CreatePageIterator(
                    graphClient, page,
                    (item) => {
                        // This code executes for each item in the
                        // collection
                        if (item is T)
                        {
                            // Only add if the item is the requested type
                            allItems.Add(item as T);
                        }
    
                        return true;
                    }
                );
    
                await pageIterator.IterateAsync();
    
                return allItems;
            }
