Azure Function Python 从其他文件import 方法失败的解决办法

使用Python Azure Functions时新建了.py文件并执行了import 操作，运行时提示如下错误：

Result: Failure
[2021-01-25T05:16:11.553Z] Exception: ModuleNotFoundError: No module named 'helper'. Troubleshooting Guide: https://aka.ms/functions-modulenotfound

Stack:   File "/usr/local/Cellar/azure-functions-core-tools@3/3.0.3233/workers/python/3.8/OSX/X64/azure_functions_worker/dispatcher.py",

解决方案：

在__init__.py文件中增加：

import sys
from sys import path
import os


dir_path = os.path.dirname(os.path.realpath(__file__))
sys.path.insert(0, dir_path)

增加完成后的默认模版建立的http trigger目录如下图所示：

修改后的__init__.py文件：

import logging
import sys
from sys import path
import os


import azure.functions as func



dir_path = os.path.dirname(os.path.realpath(__file__))
sys.path.insert(0, dir_path)


from helper import my_func

def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    name = req.params.get('name')
    if not name:
        try:
            req_body = req.get_json()
        except ValueError:
            pass
        else:
            name = req_body.get('name')
  
    
    if name:
        result = my_func(name)
        return func.HttpResponse(f"Hello, {result}. This HTTP triggered function executed successfully.")
    else:
        return func.HttpResponse(
             "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.",
             status_code=200
        )

新增的helper.py代码如下：

def my_func(str):
    result = str+'_this msg is added by my_func' 
    return result

运行调试的结果如下：
