在python2.7中如何打印邮件有效负载中的消息体

from email.parser import Parser
from email.header import decode_header

def print_email_payload(message):
    # 创建一个解析器对象
    parser = Parser()

    # 解析邮件有效负载
    email = parser.parsestr(message)

    # 获取消息体
    payload = email.get_payload()

    # 如果消息体是多部分消息，则递归打印每个部分的消息体
    if email.is_multipart():
        for part in payload:
            print_email_payload(part.get_payload(decode=True))
    else:
        # 解码消息体
        charset = email.get_content_charset()
        if charset:
            payload = payload.decode(charset)

        # 打印消息体
        print(payload)

# 邮件有效负载
email_payload = """
From: sender@example.com
To: recipient@example.com
Subject: Example Email

This is the message body.
"""

print_email_payload(email_payload)

This is the message body.
