c# - 如何在本地调试由EventGrid触发的Azure Function？

Question

我创建了一个新的 Azure 函数，希望它由 EventGrid 运行。我使用 Visual Studio 2022 社区。

我想通过 Postman 调试该函数，但找不到方法。

我的 TestFunction.cs:

public static class TestFunction
{
    [FunctionName("Function1")]
    public static async Task Function1([EventGridTrigger] EventGridEvent triggerEvent,
                                              [EventGrid(TopicEndpointUri = "Topic", TopicKeySetting = "TopicKey")] IAsyncCollector<EventGridEvent> outputEvents,
                                              ILogger log)
    {
        //TODO
    }
}

当我 F5 要调试的项目时，控制台应用程序显示:

Functions:

    Function1: eventGridTrigger

For detailed output, run func with --verbose flag.

我尝试通过 postman 发布到以下网址:

http://localhost:7071/runtime/webhooks/EventGrid?functionName=Function1

发生了两件事:

1.Postman请求返回:

cannot find function: 'Function1'

2.控制台应用程序显示:

[2022-03-14T12:20:57.717Z]   requestId: "a31453db-3717-43d8-a008-bd459a454fb0",

[2022-03-14T12:20:57.729Z]   duration: "10"
[2022-03-14T12:20:57.729Z] }

这是我阅读的用于获取调试 Url 的帖子:https://harrybellamy.com/posts/debugging-azure-function-event-grid-triggers-locally/

为了调试 Postman 的函数，我是否缺少任何东西？

提前谢谢您!

当我删除这一行(Function1 中的参数)后它就可以工作，我可以调试 Function1:

[EventGrid(TopicEndpointUri = "MyEventGridTopicUriSetting", TopicKeySetting = "MyEventGridTopicKeySetting")]IAsyncCollector<EventGridEvent> outputEvents,

引用的文章说:

If you try to send the request to the URL now, you will find that it doesn’t work. This is because Event Grid requests require a ‘magic’ header for them to work.

Add the following header to your request in your request generator:

aeg-event-type: Notification
