微软规划器 API returns HTTP 500

Question

我正在尝试使用在 Azure 门户中具有 Group.Read.All 和 Group.ReadWrite.All 权限的已注册应用程序，通过 GraphServiceClient 读取单个计划的所有计划任务。

我已经尝试使用 Microsoft.Graph 和 Microsoft.Graph.Beta 包，但在调用任何计划程序 api 端点时，我总是会收到 InternalServerError。

使用以下代码设置 GraphServiceClient

IConfidentialClientApplication confidentialClientApplication = ConfidentialClientApplicationBuilder
             .Create("ClientId")
             .WithTenantId("TenantId")
             .WithClientSecret("ClientSecret")
             .Build();

ClientCredentialProvider clientCredentialProvider = new ClientCredentialProvider(confidentialClientApplication);

GraphServiceClient graphClient = new GraphServiceClient(clientCredentialProvider);

工作正常。使用

呼叫群组 api

try
{
    Task<IGraphServiceGroupsCollectionPage> groups = graphClient.Groups
        .Request()
        .GetAsync();
    groups.Wait();

    foreach (var item in groups.Result)
    {
        Console.WriteLine(item.DisplayName);
    }
}
catch (Exception e)
{
    Console.WriteLine(e);
}

也有效。但是调用规划器API

try
{
    Task<PlannerPlan> plan = graphClient.Planner.Plans["PlanId"]
        .Request()
        .GetAsync();
    plan.Wait();
    Console.WriteLine(plan.Result.Title);
}
catch (Exception e)
{
    Console.WriteLine(e);
}

仅抛出预期 “/taskApi”应用程序中的服务器错误。

虽然我必须更改身份验证提供程序，但可以使用我的 Microsoft 帐户。

我的代码中缺少什么吗？

编辑：工作代码

感谢@Jim Xu，我的代码可以正常工作了。对于任何运行遇到相同问题的人，这里是工作示例。我必须将客户端密码添加到所有请求的 headers，但它仍然有效。

IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
.Create("CLientId")
.WithTenantId("TenantId")
.Build();
String[] scopes = new String[] { "Group.Read.All", "Group.ReadWrite.All" };
Func<DeviceCodeResult, Task> deviceCodeReadyCallback = async dcr => await Console.Out.WriteLineAsync(dcr.Message);

DeviceCodeProvider authProvider = new DeviceCodeProvider(publicClientApplication, scopes, deviceCodeReadyCallback);

GraphServiceClient graphClient = new GraphServiceClient(authProvider);
IGraphServiceGroupsCollectionRequest groupRequest = graphClient.Groups.Request();
groupRequest.Headers.Add(new HeaderOption("client_secret", "ClientSecrect"));

Task<IGraphServiceGroupsCollectionPage> groups = groupRequest.GetAsync();
groups.Wait();

foreach (var item in groups.Result)
{
    Console.WriteLine(item.DisplayName);
}

根据您的代码，您使用客户端凭据流程调用 Microsoft 计划 API。换句话说，您使用应用程序权限来调用 Microsoft Graph Plan API。这是错误的。根据official document，我们可以直接使用Delegated权限来调用API。所以你会得到错误。

关于如何用SDK调用api，请参考以下代码（本人在控制台应用测试）

配置您的 Azure AD 应用程序

一个。打开 allowPublicClient 设置

b。更新 API 权限。请添加要求委派权限：Group.Read.All、Group.ReadWrite.All
代码

  string clientId = "";
            string tenantId = "";
            IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
            .Create(clientId)
            .WithTenantId(tenantId)
            .Build();
            var scopes = new string[] { "Group.Read.All", "Group.ReadWrite.All" };
            Func<DeviceCodeResult, Task> deviceCodeReadyCallback = async dcr => await Console.Out.WriteLineAsync(dcr.Message);

            DeviceCodeProvider authProvider = new DeviceCodeProvider(publicClientApplication, scopes, deviceCodeReadyCallback);
            GraphServiceClient graphClient = new GraphServiceClient(authProvider);
            Task<PlannerPlan> plan = graphClient.Planner.Plans["Lc1LT2z1aEqnACVeA8KtIGUABIeE"]
                .Request()
                .GetAsync();
             plan.Wait();
             Console.WriteLine("The plan tiltel : " + plan.Result.Title);
            Console.ReadLine();
