问题描述

我正在使用 Azure AD 中的应用程序身份并授予读写权限，我还运行了 Grant-CsApplicationAccessPolicy，以便应用程序身份有权代表 Azure AD 中的真实用户身份创建在线会议

I'm using an application identity from Azure AD with both read write permission granted, I've also run the Grant-CsApplicationAccessPolicy so that the application identity has right to create online meeting on behalf of a real user identity from Azure AD

我知道我的设置适用于从图形 api 获取用户.但是，运行以下命令后出现错误:

I know my setup works with get user from the graph api. However, I'm getting error after running the following:

            var confidentialClient = ConfidentialClientApplicationBuilder
                .Create(clientId)
                .WithAuthority($"https://login.microsoftonline.com/{tenantId}/v2.0")
                .WithClientSecret(clientSecret)
                .Build();

            GraphServiceClient graphServiceClient =
                new GraphServiceClient("https://graph.microsoft.com/beta", new DelegateAuthenticationProvider(async (requestMessage) =>
                {

                        var authResult = await confidentialClient
                            .AcquireTokenForClient(scopes)
                            .ExecuteAsync();

                        requestMessage.Headers.Authorization =
                            new AuthenticationHeaderValue("Bearer", authResult.AccessToken);
                })
                    );

                var onlineMeeting = new OnlineMeeting
                {
                    StartDateTime = DateTimeOffset.Parse("2020-12-25T21:30:34.2444915+00:00"),
                    EndDateTime = DateTimeOffset.Parse("2020-12-25T22:00:34.2464912+00:00"),
                    Subject = "User Token Meeting 1"
                    
                };

                var meetingInstance = await graphServiceClient.Me.OnlineMeetings
                    .Request()
                    .AddAsync(onlineMeeting);

错误信息如下，为什么会显示User lookup by user id failed in AAD?

The error message is as follow, why would it say User look up by user id failed in AAD?

推荐答案

Dev 是正确的.

基于此 文档:

使用应用程序令牌时的请求:POST/users/{userId}/onlineMeetings.

Request when using an application token: POST /users/{userId}/onlineMeetings.

所以你应该在这里使用 graphServiceClient.Users["{userId}"].OnlineMeetings 而不是 graphServiceClient.Me.OnlineMeetings.

So you should use graphServiceClient.Users["{userId}"].OnlineMeetings instead of graphServiceClient.Me.OnlineMeetings here.

userId 是用户的对象ID.当您 配置应用访问策略，您需要将该策略授予用户:

userId is the object ID of a user. When you Configure application access policy, you need to grant the policy to the user:

Grant-CsApplicationAccessPolicy -PolicyName Test-policy -Identity "ddb80e06-92f3-4978-bc22-a0eee85e6a9e"

ddb80e06-92f3-4978-bc22-a0eee85e6a9e 正是 userId.

我的代码供你参考:

        // Configure the MSAL client as a confidential client
        var confidentialClient = ConfidentialClientApplicationBuilder
            .Create("{client_id}")
            .WithTenantId("{tenant_id}")
            .WithClientSecret("{client_secret}")
            .Build();

        ClientCredentialProvider authProvider = new ClientCredentialProvider(confidentialClient);

        GraphServiceClient graphServiceClient = new GraphServiceClient(authProvider);

        var onlineMeeting = new OnlineMeeting
        {
            StartDateTime = DateTimeOffset.Parse("2021-01-12T21:30:34.2444915+00:00"),
            EndDateTime = DateTimeOffset.Parse("2021-01-12T22:00:34.2464912+00:00"),
            Subject = "User Token Meeting123"
        };

        var meeting = await graphServiceClient.Users["{userId}"].OnlineMeetings
            .Request()
            .AddAsync(onlineMeeting);
