Question

我的python脚本（如下所示）可以发送“.txt”附件，但不幸的是收到的附件丢失了“\ n”，因此所有行都在一起，这破坏了我的列格式。有人可以帮我一个忙吗？非常感谢！

msg['From'] = send_from
msg['To'] = COMMASPACE.join(send_to)
msg['Date'] = formatdate(localtime=True)
msg['Subject'] = 'Subject of Email4'

mailbody = "This is the content of Email4"
msg.attach(MIMEText(mailbody))

with open("regresult.txt", "r") as fil:
    part = MIMEApplication(
        fil.read(),
        Name=basename("regresult.txt")
    )
    part['Content-Disposition'] = 'attachment; filename="%s"' % basename('regresult.txt')
    msg.attach(part)

更新：原始文件（在带有VIM的远程Unix服务器中打开）如下所示：original file format

收到的文件格式如下：received

Answer 1

感谢@ gixxer的提示。这是txt文件本身的格式问题。原始txt中的行尾字符是＆＃34; \ n＆＃34;它适用于Unix系统，但不适用于Windows。 Windows使用＆＃34; \ r \ n＆＃34;代替。所以我只想添加＆＃34; \ r \ n＆＃34;到原始文件中每一行的末尾，然后它就可以了。

import smtplib
import io

sender = 'from@fromdomain.com'
receivers = ['to@todomain.com']
file = io.open('newfile.txt', 'r')

message = file.readlines()

try:
    smtpObj = smtplib.SMTP('localhost')
    smtpObj.sendmail(sender, receivers, message)
    print("Successfully sent email")
except Exception:
    print("Error: unable to send email")

Python电子邮件附件丢失了换行符“\ n”
