python - 计时器触发 azure 函数 python v2 模型 - 部署到 azure 后，它显示 "no http trigger found "

Question

我正在尝试使用 python v2 model 将时间触发(计划)函数部署到 azure 函数。该函数在本地按预期工作。我正在使用 VSCode 和 Azurite 扩展进行部署。部署似乎成功，但它说“未找到 HTTP 触发器”(这没有任何意义，因为它不是 HTTP triffered 函数)，并且该函数实际上未部署到 Azure。这里可能出了什么问题？

function_app.py

import azure.functions as func

import datetime
import logging
import requests
import json
import sys
import os

CRON_SCHEDULE = "*/10 * * * * *"

app = func.FunctionApp()
@app.function_name(name="testSendReqToApiTimeTrigger")
@app.schedule(schedule=CRON_SCHEDULE, arg_name="mytimer", run_on_startup=False, use_monitor=True)
def makeApiCall(mytimer: func.TimerRequest, context: func.Context) -> None:
    
    if mytimer.past_due:
        logging.info('The timer is past due!')

    logging.info('.context_func_dir: ' + context.function_directory)

    url = "http://worldtimeapi.org/api/timezone/Europe/Amsterdam"

    try:
        response = requests.get(url)
        print(f"request completed with status code: {response.status_code}")

    except:
        logging.error("ERROR during sending request : ")
        logging.error(str(sys.exc_info()))

部署过程输出的最后几行:

来自给定MS Doc的源代码.

import  azure.functions  as  func
import  logging
import  datetime
  
app = func.FunctionApp()

@app.function_name(name="mytimer")
@app.schedule(schedule="0 */5 * * * *", arg_name="mytimer", run_on_startup=True,
use_monitor=False)
def  test_function(mytimer: func.TimerRequest) -> None:
utc_timestamp = datetime.datetime.utcnow().replace(
tzinfo=datetime.timezone.utc).isoformat()


if  mytimer.past_due:
logging.info('The timer is past due!')
logging.info('Python timer trigger function ran at %s', utc_timestamp)

当我部署 Python v2 计时器触发的 Azure 函数时，它给出相同的结果，因为实际的本地函数项目不包含任何 HTTP 触发函数。

但是我在 Azure Function App Portal 中获取了这些函数:

因为在Python V2编程模型中，我们必须在Portal Function App Configuration中显式添加一个应用程序设置:

"AzureWebJobsFeatureFlags": "EnableWorkerIndexing"
