在 Python 中发送带有 zip 文件的电子邮件

Question

脚本正在运行，我收到了 zip 文件。但是，当我尝试打开 zip 文件（WinRaR 和 7-zip）时，出现错误 - 存档格式未知或已损坏。可能与编码有关？？？

from email.mime.multipart import MIMEMultipart
from email.mime.application import MIMEApplication
from email.mime.text import MIMEText
import smtplib


def send_mail():
    sender = '*****@mail.ru'
    password = '*************'

    smtp_obj = smtplib.SMTP('smtp.mail.ru', 587)
    smtp_obj.starttls()
    
    msg = MIMEMultipart()
    msg['Subject'] = 'Data from Experiment'
    msg['From'] = sender
    msg['To'] = sender
    
    with open(r'C:\Users\Admin\Desktop\Python\Python + SQL\Send_email\arch\arch.zip',encoding='CP866') as file:
    # Attach the file with filename to the email
        msg.attach(MIMEApplication(file.read(), Name='arch.zip'))

    

    # Login to the server
    smtp_obj.login(sender, password)

    # Convert the message to a string and send it
    smtp_obj.sendmail(sender, sender, msg.as_string())
    #smtp_obj.quit()

send_mail()

Answer 1

打开 zip 文件时不要传递编码。那是二进制数据，应该这样对待！ open(..., 'b')
