python-3.x - python中的SES电子邮件附件

问题描述

使用 Python 3.7，在 lambda 包中部署一个文本文件：'sample.txt'，并将 python 程序的日志写入该文本文件。现在，我正在尝试附加此文本文件并使用 mime 库通过 aws-SES 发送电子邮件。注意：在 Lambda 函数中执行整个程序。这是我在 lambda 函数中的代码：

import json, boto3
import logging as logger
import pathlib
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import os

def lambda_handler(event, context):

    #path = pathlib.Path().absolute()
    filename = ‘/tmp/sample.txt'
    logger.basicConfig(filename=filename, format='%(message)s',
                    level=logger.DEBUG, filemode='wt')
    #write these logs to text file
    logger.info(filename)
    logger.warning('233')
    logger.error('....')

    from = "abc@sample.com"
    to = "xyz@sample.com"
    region = "sample region"
    subject = "sample email"

    body = """<html>
    <head></head>
    <body>
      <h1>Test</h1>
      <p>This email was sent for testing</p>
    </body>
    </html>
               """            
    ses = boto3.client('ses',region_name=region)

    msg = MIMEMultipart()
    msg["Subject"] = subject
    msg["From"] = from
    msg["To"] = to

    body_txt = MIMEText(body, "html")
    msg.attach(body_txt)
    fo= open(filename, 'rb')
    file_content =fo.read()
    attachment = MIMEApplication(file_content)
    fo.close()
    attachment.add_header("Content-Disposition", "attachment", filename=filename)
    msg.attach(attachment)

    response = ses.send_raw_email(Source = from, Destinations = [to], RawMessage = {"Data": msg.as_string()})

"errorMessage": "[Errno 2] 没有这样的文件或目录：'/var/task/sample.txt'",

  1. 这是因为 /var/task 在执行完函数后会被删除吗？
  2. 在 S3 中保存文本文件，是唯一的选择吗？
