Azure函数中的http和计时器都触发 [英] Both http and timer trigger in Azure Function

问题描述

通过复制项目文件夹，我可以在Azure函数中同时使用计时器和http触发器.这样，我就有一个单独的 function.json ，在其中可以为一个指定计时器触发器，为另一个指定一个http触发器，请参见 src_http 和 src_timer 下方:

I am able to have both a timer and http trigger in my Azure Function by duplicating the project folder. This way I have a seperate function.json where I can specify a timer trigger for one and a http trigger for the other, see src_http and src_timer below:

这绝对是不可取的，因为我正在复制代码.

This is definitely not desireable, since I am duplicating my code.

问题:是否可以在一个功能中同时使用计时器和http触发器?

Question: Is there a way to have both a timer and http trigger in one function?

我阅读了此，看来这是不可能的，我希望我错了.

I read this and it looks like this is not possible, I hope I am wrong.

推荐答案

请参见在Java中，您可以执行以下操作，因为它在生成的 function.json 中使用 class-name.function-name 作为"scriptFile" 代码>:

In java you can do something like this because it uses class-name.function-name as "scriptFile" in generated function.json:

    public class EhConsumerFunctions {
        private void processEvent(String request, final ExecutionContext context) {
         // process...
        }

        @FunctionName("HttpTriggerFunc")
        public void httpTriggerFunc(
           @HttpTrigger(name = "req", methods = {HttpMethod.GET}, authLevel = AuthorizationLevel.ANONYMOUS)
           HttpRequestMessage<Optional<String>> req,
           final ExecutionContext context) {
           processEvent(req.getBody().get(), context);
       }

       @FunctionName("TimerTriggerFunc")
       public void timerTriggerFunc(
        @TimerTrigger(name = "timerRequest", schedule = "0 */5 * * * *") String timerRequest,
        final ExecutionContext context) {
           processEvent(timerRequest, context);
       }

    }

对于python，它采用脚本名称，并希望它具有 main 和单独的 function.json .因此，您将必须有两个文件夹和两个脚本.但是每个脚本都可以 import 一个通用的业务逻辑模块来执行实际的处理.

For python, it takes script name and expects it to have a main and separate function.json. So you'll have to have two folders and two scripts. But each script can import a common business logic module which does the actual processing.

类似的东西:

MyFunctionApp
|____ host.json
|____ business
|     |____ logic.py
|____ http_trigger
|     |____ __init__.py
|     |____ function.json
|____ timer_trigger
      |____ __init__.py
      |____ function.json

http_trigger/__ init __.py 将具有:

from business import logic

def main(req: func.HttpRequest) -> func.HttpResponse:
    return logic.process(req)

和 http_trigger/function.json 将具有:

    {
        "scriptFile": "http_trigger/__init__.py",
        "disabled": false,
        "bindings": [
            {
                "authLevel": "function",
                "type": "httpTrigger",
                "direction": "in",
                "name": "req"
            },
            {
                "type": "http",
                "direction": "out",
                "name": "res"
            }
        ]
    }
