通過Microsoft.Graph邀請用戶會出現錯誤

Question

預期行為

應該邀請用戶，然后用更多信息更新該用戶https://docs.microsoft.com/zh-cn/graph/api/invitation-post?view=graph-rest-1.0

實際行為

資源

"Microsoft.Graph.Core"

信息

"Code: Unauthorized\r\nMessage: Insufficient privileges to perform requested operation by the application '00000003-0000-0000-c000-000000000000'. ControllerName=MSGraphInviteAPI, ActionName=CreateInvite, URL absolute path=/api/9cXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/invites\r\n\r\nInner error\r\n"

堆棧跟蹤

重現行為的步驟

SDK版本：netcoreapp2.2
“ Microsoft.Graph”版本=“ 1.13.0”“ Microsoft.Graph.Core”版本=“ 1.13.0”

IDE版本：VS Code-1.31.1 Vsiual Studio Enterprise 2017-4.7.03056

我有此方法（將創建GraphServiceClient的代碼移到該方法中以證明觀點），客戶端通過App注冊進行身份驗證（我獲得了訪問令牌），但是當運行Invite的代碼運行時，authenticationContext.AcquireTokenAsync再次觸發並我上面的堆棧跟蹤出現錯誤。 根據API文檔，客戶端應用程序具有User.Invite.All，User.ReadWrite.All，Directory.ReadWrite.All。

為什么將AppId在代碼中更改為以上消息中的代碼？

public async Task<string> CreateUser(CreateUserCommand user)
        {
            try
            {
                var clientCredential = new ClientCredential(_configuration["appId"], _configuration["secret"]);
                var authenticationContext = new AuthenticationContext(_configuration["authority"]);
                var authenticationResult = authenticationContext.AcquireTokenAsync("https://graph.microsoft.com", clientCredential).Result;

                var delegateAuthProvider = new DelegateAuthenticationProvider((requestMessage) =>
                {
                    requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", authenticationResult.AccessToken);

                    return Task.FromResult(0);
                });

                var con = new GraphServiceClient(delegateAuthProvider);

                //invite user
                Invitation invitation = new Invitation();
                invitation.InvitedUserDisplayName = user.Name;
                invitation.SendInvitationMessage = true;
                invitation.InvitedUserEmailAddress = user.Email;
                invitation.InviteRedirectUrl = "http://localhost";
                var result = await con.Invitations.Request().AddAsync(invitation);

                //update user
                var aadUser = _connection.GetConnection().ActiveDirectoryUsers.GetById(result.Id);
                var updateUser = result.InvitedUser;
                updateUser.DisplayName = user.Name;
                updateUser.Surname = user.Surname;
                updateUser.Mail = user.Email;
                updateUser.MobilePhone = user.Phone;
                await con.Users[result.InvitedUser.Id].Request().UpdateAsync(updateUser);
                return aadUser.UserPrincipalName;
            }
            catch (System.Exception)
            {

                throw;
            }


        }

CreateUserCommand：

public class CreateUserCommand
    {
        public string Name { get; set; }
        public string Surname { get; set; }
        public string Email { get; set; }
        public string Phone { get; set; }
    }

這是應用程序注冊的截圖

權限：

IConfiguration對象中的應用ID

Answer 1

委派權限僅在您在用戶上下文中調用API時才重要。

由於您使用的是客戶端憑據，因此沒有用戶。 僅應用程序權限適用，因此請在此處設置正確的權限。

另外，由於您具有異步功能，因此最好也等待令牌：

var authenticationResult = await authenticationContext.AcquireTokenAsync("https://graph.microsoft.com", clientCredential);
