Question

我在尝试测试我的 lambda 函数时遇到此错误

  "errorMessage": "Unable to import module 'app': No module named 'app'",
  "errorType": "Runtime.ImportModuleError",
  "stackTrace": []
}

这是我的 python 代码，因为我认为这是我的代码的问题？我还将 aws 上的 lambda 函数处理程序设置为 app.handler，因为该文件的名称是 app.py。真的不确定这是否是我的 lambda 函数处理程序或我的代码或两者的问题

import requests
import os
import smtplib
from datetime import datetime

# https://openweathermap.org/api/one-call-api

# empire state building
lat = '40.75009231913161'
lon = '-73.98638285425646'
exclude = 'minutely,hourly,alerts'

url = (
    'https://api.openweathermap.org/data/2.5/onecall?' +
    'lat={lat}&lon={lon}&exclude={exclude}&appid={API_key}&units=imperial'
)


if os.path.isfile('.env'):
    from dotenv import load_dotenv
    load_dotenv()


def __send_email(msg: str) -> None:
    gmail_user = os.getenv('EMAIL_USER')
    gmail_password = os.getenv('EMAIL_PASSWORD')

    # Create Email
    mail_from = gmail_user
    mail_to = gmail_user
    mail_subject = f'Weather Today {datetime.today().strftime("%m/%d/%Y")}'
    mail_message = f'Subject: {mail_subject}\n\n{msg}'

    # Send Email
    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.starttls()
    server.login(gmail_user, gmail_password)
    server.sendmail(mail_from, mail_to, mail_message)
    server.close()


def handler(event, context):
    response = requests.get(url.format(
        lat=lat,
        lon=lon,
        exclude=exclude,
        API_key=os.getenv('WEATHER_API_KEY')
    ))

    data = response.json()

    rain_conditions = ['rain', 'thunderstorm', 'drizzle']
    snow_conditions = ['snow']

    today_weather = data['daily'][0]['weather'][0]['main'].lower()

    if today_weather in rain_conditions:
        msg = 'Pack an umbrella!'
    elif today_weather in snow_conditions:
        msg = 'Pack your snow boots!'
    else:
        msg = 'Clear skies today!'

    __send_email(msg)

handler(None, None)

我的 ZIP 位于 python/project.zip 中的 S3 存储桶中，我的 zip 文件夹的结构是 python/app.py + requirements.txt

Answer 1

the structure of my zip folder is python/app.py + requirements.txt

应该只是app.py，而不是python/app.py。也不需要 requirements.txt 因为 lambda 不会使用它并安装你在那里列出的任何包。
