c# - 通过 Microsoft Graph API 订阅消息，无需用户交互

问题描述

我正在尝试使用 Microsoft Graph API 在没有用户交互的情况下创建一个订阅 Office 365 中的邮件事件（新邮件、创建、更新）的应用程序。如果有新电子邮件，我想向使用 C# MVC5 和 .Net 4.5 构建的应用程序发送通知。我正在关注的一个示例是在 Github 中（使用 Daemon Service Github 项目 Link），但它是在 .Net Core 中构建的。我遇到了另一个使用 WebJobs 的应用程序，它非常接近我的
Azure webjobs要求，但它在过去 2 年没有更新。我遵循了这些步骤，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？

应用设置：

应用设置：

<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==" />

我试图重新创建应用程序得到以下问题 Trace

编辑1：

我能够使用类似于此处描述的 Outlook 连接器和 Office 365 Webhook API（使用 azure logic App 中可用的默认连接器）完成接收电子邮件（无需用户登录） 。但是，Outlook 连接器每 x 秒（我设置的自定义值）轮询邮箱中的任何更改，但我希望服务自动触发 Webhook 事件而不进行轮询。如果我理解正确的话，应该是这样的——

  1. 创建一个已注册以监视事件的 webhook

  2. 创建一个使用上述 webhook 的 Outlook 连接器。

  3. Outlook 连接器将通知应用程序（REST API 调用）作为工作流的一部分。

解决方案

以下是一些需要考虑的关键点：

  • 无论您使用什么语言/平台，使用 Microsoft Graph Webhook 通知都是一样的。唯一的区别是您托管通知端点的方式/位置。

  • 要在没有用户交互的情况下订阅通知，您的应用需要仅应用权限

您可能想查看 Azure Functions；它们为 Microsoft Graph 提供了一些易于使用的绑定：https ://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-microsoft-graph
