通过Microsoft Graph API订阅消息，无需用户交互

Question

我正在尝试创建一个应用程序，该应用程序使用Microsoft Graph API在Office 365中订阅邮件事件（新邮件，创建，更新），而无需用户交互。如果有新电子邮件，我想向使用 C# MVC5 和 .Net 4.5 构建的应用发送通知。我下面的一个例子是在Github中（使用Daemon Service Github项目链接），但它是在.Net Core中构建的。我遇到了另一个使用 Web 作业的应用程序，它非常接近我的要求
Azure 网络作业，但它在过去 2 年中没有更新。我按照步骤操作，但其中大多数与我的 Azure 开发人员帐户（免费）不匹配。有人可以帮我吗？

应用程序设置:

应用程序设置:

<add key="tenantId" value="[Tenant_ID]" />
    <add key="clientId" value="[AppID]" />
    <add key="clientSecret" value="[Client Secret]" />
    <add key="webjobs" value="DefaultEndpointsProtocol=https;AccountName=onvidawebjob1aa1b;AccountKey=Z3xewALbEc43gE/dL06HxCGIjVtpaiTkIY4ZolkjZt9Z86xHIZLzMwXBlujNI8/PcTJbM1LIs5KNceVTGgESmA==" />
    <add key="subscriptionblobname" value="subscriptions/subscription1" />
    <add key="notificationurl" value="https://onvidawebjob1.azurewebsites.net/api/HttpTrigger1?code=H7liZOlcQc5qjcZOkRXEb0x4JVqTzoXnrl6mAswsEKl4LlmAYm/ACw==" />

我尝试重新创建应用程序，但出现以下问题跟踪

我能够使用outlook connector和office 365 webhook API(使用azure logic应用程序中可用的默认连接器)完成接收电子邮件(无需用户登录),类似于这里描述的内容。但是，outlook connector每隔x秒(由我设置的自定义值)html" target="_blank">轮询一次邮箱中的任何更改，但是我希望该服务在不轮询的情况下自动触发Webhook事件。如果我理解正确的话，应该是这样的——

> < li>

创建注册的webhook以监视事件

创建一个使用以上webhook的outlook connector。

Outlook connector在工作流中通知应用程序(REST API调用)。

以下是需要考虑的一些要点：

> < li>

无论您使用何种语言/平台，使用Microsoft Graph webhook通知都是一样的。唯一的区别是您如何/在哪里托管您的通知endpoint。

要在没有用户交互的情况下订阅通知，您的应用需要仅限应用的权限
