问题描述

我想使用Python更改收件人"和发件人"字段的电子邮件地址.到目前为止，我已经完成了以下工作，以读取必填字段.任何人都可以提出建议，如何在其中做出改变.

I would like to have a changes of "To" and "From" field's email addresses using Python. So far now I did following which is working for reading required field. Any one please suggest, How to make change in them.

from email.parser import Parser

fp = open('2.eml', 'r+')
headers = Parser().parse(fp)

# Make changes only within a code, Not in to the file. I would like to save given changes for from in to my 2.eml file
headers.replace_header('from', '[e-mail]') 

print ('To: %s' % headers['to'])
print ('From: %s' % headers['from'])
print ('Subject: %s' % headers['subject'])

推荐答案

您应将更改后的消息写回到文件中:

You should write the changed message back to the file:

with open('2.eml', 'w') as outfile:
    outfile.write(headers.as_string())

请注意，您的姓名headers并不完全准确，因为

Note that your name headers is not completely accurate as the value returned by email.parser.Parser.parse is email.message.Message.
