Outlook 365 Rest API - 受众声明值无效

Question

我正在处理一个我们已经使用 Identity Server 进行身份验证的项目。在这里，我们使用访问令牌访问 microsoft Graph API 以获取会议、个人资料图片和其他内容。

现在我们想要集成到新的 Outlook 365 API 以读取和在未来写入任务。

我正在尝试使用已经存在的访问令牌从 Outlook restapi 获取 Outlook 任务：

在身份服务器上，我们使用中间件来处理我们的作用域，如下所示：

        app.UseMicrosoftAccountAuthentication(new MicrosoftAccountOptions
        {
            AuthenticationScheme = "Microsoft",
            DisplayName = "Microsoft",
            SignInScheme = cookieScheme,
            ClientId = Configuration.GetValue<string>("ExternalKeys:SecretMicrosoftClientId"),
            ClientSecret = Configuration.GetValue<string>("ExternalKeys:SecretMicrosoftClientSecret"),
            CallbackPath = new PathString("/signin-microsoft"),
            Scope =
            {
                "offline_access",
                "Calendars.Read",
                "Calendars.Read.Shared",
                "https://outlook.office.com/tasks.read"
            },

            SaveTokens = true,

        });

当我们尝试登录时，系统会提示我们额外的任务访问要求。所以我们应该可以访问任务 API。

还有其他人尝试同时使用 Microsoft 图形 API 和新的 Outlook 365 Rest API 吗？

Answer 1

新答案：
Api 现已发布，可在此处找到 https://msdn.microsoft.com/en-us/office/office365/api/task-rest-operations

我们项目的工作范围：

Scope =
{
    "offline_access",
    "Calendars.Read",
    "Calendars.Read.Shared",
    "Tasks.Readwrite"
},

旧答案：

您不能针对 Outlook 端点使用为 Graph ("aud": "https://graph.microsoft.com") 颁发的令牌。您需要一个带有"aud": "https://outlook.office.com" 的令牌。为此，您需要向 Azure 发出另一个身份验证请求，其中所有范围都完全符合 Outlook 域：

Scope =
{
    "offline_access",
    "https://outlook.office.com/Calendars.Read",
    "https://outlook.office.com/Calendars.Read.Shared",
    "https://outlook.office.com/tasks.read"
},

但是，由于您已经在使用 Graph，您也可以通过 Graph 访问任务 :)。 Graph 最近为其 beta 端点添加了任务支持：https://developer.microsoft.com/en-us/graph/docs/api-reference/beta/resources/outlooktask。
