Linux終端一行命令发送邮件

近期由于经常需要给别人发送邮件，每次都要打开QQ邮箱觉得非常麻烦。想到Linux终端可以自定义命令，加上python可以实现邮件发送功能，于是自己写了一个终端send + 文件地址的命令。

首先贴上python发送邮件的代码。

# An automatically send qq_email lib
# python3
# author: lunar_ubuntu
# -*- coding: UTF-8 -*-

import sys
import smtplib
from email.mime.text import MIMEText
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.header import Header
from xml.dom.minidom import parse
import xml.dom.minidom

dom_tree = xml.dom.minidom.parse("info.xml") # here you need to fill your xml file path
elem = dom_tree.documentElement

sender = elem.getElementsByTagName("sender")[0]
sender_acount = sender.getElementsByTagName("sender_acount")[0].childNodes[0].data
sender_pwd = sender.getElementsByTagName("sender_pwd")[0].childNodes[0].data

recevs = elem.getElementsByTagName("receivers")[0]
receivers = []
for re in recevs.getElementsByTagName("receiver_acount"):
    receivers.append(re.childNodes[0].data)

def mail(*file_paths):
    res = True
    message = MIMEMultipart()
    message['From'] = Header("ubuntu",'utf-8')
    message['TO'] = Header("windows", 'utf-8')
    subject = 'ubuntu send files'
    message['Subject'] = Header(subject,'utf-8')
    for path in file_paths[0]:
        #print("path: %s" % path)
        file_name = split_path(path)
        #print("file_name: %s" % file_name)
        attach = MIMEApplication(open(path,'rb').read())
        attach['Content-type'] = 'application/octet-stream'
        attach['Content-Disposition'] = 'attachment; filename="' + file_name + '"'
        message.attach(attach)

    server = smtplib.SMTP_SSL("smtp.qq.com", 465)
    server.login(sender_acount, sender_pwd)
    server.sendmail(sender_acount, receivers, message.as_string())
    server.quit()
    return res

def split_path(path):
    return path.split('/')[-1]

if __name__ == '__main__':
    res = mail(sys.argv[1:])
    if res:
        print("successfully send emails!")
    else:
        print("failed to send emails!")

我是通过将邮箱信息写在xml文件里面来读取的，这样方便修改。不用每次都修改源代码。xml也贴一下。

<info>
<sender>
    <sender_acount>mail_address</sender_acount>
    <sender_pwd>put your password here</sender_pwd>
</sender>
<receivers>
    <receiver_acount>2100125584@qq.com</receiver_acount>
    <receiver_acount>2100125584@qq.com</receiver_acount>
</receivers>
</info>

这里面的邮箱密码并不是你登录邮箱的那个密码，而是在邮箱里面的账号设置里获得的第三方登录码。具体可以看一下菜鸟教程的python发送邮件的那个教程。还不懂可以在评论区问我。

最后修改~/.bashrc文件，加上一句alias send="python3 [文件地址]"。然后保存退出后输入命令sourcr ~/.bashrc是命令生效。然后就可以通过send命令来发送文件啦！
