django发送邮件，当附件是js文件时，收到的邮件是js.txt。

Question

django发送邮件，当附件是js文件时，收到的邮件是js.txt。当压缩js文件时，rar可以的，zip会解析成zip.txt。

各位大神有没有类似的经历，或者思路

补充代码：

import os,json,threading,datetime
os.environ['DJANGO_SETTINGS_MODULE'] = '####.settings'

from django.core.mail import EmailMultiAlternatives
from django.core.mail import send_mail
