2023-04-29

如果单纯使用python定时发送很简单,但是国内无法直接连接gmail邮件,需要使用vpn做桥接然后登陆发邮件

代码梳理过程如下

单纯使用上面代码再国内是无法发送邮件的，因为有墙的原因

给邮件设置vpn的代理

import socks
import socket
#12345为vpn的端口号，请自行查看对应的端口号
socks.setdefaultproxy(socks.HTTP, 'localhost', 12345)
socket.socket=socks.socksocket

上述代码已经可以使邮件协议走vpn的通道

control = MailControl("smtp.gmail.com", "gmail用户名", "gmail密码","gmail用户名<gmail用户名@gmail.com>")
control.login() #登录
mail="kehu@gmail.com"
msg = control.createHeader("发送邮件标题", ["%s<%s>" % ("客户邮件名", mail)], [], [])
msg = control.addContent(msg, "<p>邮件正文</p>", "html")
for attach in attachs:
    #有附件添加附件
    msg = control.addAttach(msg, attach)
rev = control.send(msg, [mail])
control.quit()

使用上诉代码即可用gmail给客户发送邮件
