手动触发 Azure 函数 - 时间触发 [英] Manually trigger Azure Function - Time triggered

问题描述

我有一个每周在计时器触发器上运行一次的 Azure 函数.这效果很好，正如预期的那样，但大约每月一次或两次，用户需要根据请求运行此功能，因此我需要发布该功能以触发它 - 就像您可以从 Azure 门户执行的操作一样.

I have an Azure Function that runs on a timer trigger once a week. This works great and as expected, but about once or twice a month, a user needs this function to run upon request, so I need to do a post to the function to trigger it - much like you can do from the Azure portal.

查看 Azure 门户，正在对函数执行 http post 请求，例如:

Looking at the Azure portal, a http post request is being done to the function like:

https://{funcapp}.azurewebsites.net/admin/functions/{func}

但是，如果我从 Postman 执行此操作，我会收到 Http 401 响应.我将如何处理这个请求?

However, if I do this from Postman, I get a Http 401 response. How would I go about to do this request?

我有一个选项，我宁愿将触发器更改为队列，并每周运行第二个函数，将消息添加到队列中，但这对我来说似乎有点过分.

One option I have a to rather change the trigger to a queue and have a second function run on the weekly basis that would add a message to the queue, but this seems a bit excessive to me.

推荐答案

如果利用单个函数应用可以由多个函数组成的事实，在函数之间共享业务逻辑怎么办?然后你可以有一个基于 HTTP 请求的 function.json 触发器和另一个基于计时器的触发器.

What if you share business logic between functions by using the fact that a single function app can be composed of multiple functions? Then you can have one function.json trigger based off of an HTTP request and the other trigger based off of a timer.

您的函数应用架构可能如下所示:

Your function app architecture could look like:

MyFunctionApp
|     host.json
|____ shared
|     |____ businessLogic.js
|____ function1
|     |____ index.js
|     |____ function.json
|____ function2
      |____ index.js
      |____ function.json

在function1/index.js"和function2/index.js"中

var logic = require("../shared/businessLogic");

module.exports = logic;

function1 和 function2 的 function.json 可以配置为不同的触发器(定时器和 HTTP 或队列......任何你想要的！).

The function.json of function1 and function2 can be configured to different triggers (timer and HTTP or queue... whatever you want!).

在shared/businessLogic.js"中

module.exports = function (context, req) {
    // This is where shared code goes. As an example, for an HTTP trigger:
    context.res = {
        body: "<b>Hello World</b>",
        status: 201,
        headers: {
            'content-type': "text/html"
        }
    };     
    context.done();
};

(这是一个 JavaScript 示例，但同样适用于其他语言！)

(This is a JavaScript example, but same holds for other languages!)
