:以qq邮箱为例
使用的场景:
(1) 目前用在了重置用户密码
(2) 项目需要发送测试报告到用户邮箱
(3) 之前见过一个用户使用邮件的形式维护linux服务器(服务器端需要接收邮件进行解读)
写代码前要准备的:
(1) 需要准备一个QQ号,因为要以这个QQ号发送和接受邮件。
(2) 需要这个QQ号邮箱开启SMTP/POP3服务
# 点开会验证,验证完会给个授权码,之后就是通过这个授权码代替用户密码
提醒:直接修改if __main__里的内容即可
发送邮件:
import os
import random
import smtplib
import time
from email.header import Header
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
class MyEmail(object):
def __init__(self, sender, receiver, username, password, smtp_server='smtp.qq.com'):
self.sender = sender
self.receiver = receiver
self.username = username

self.smtp_server = smtp_server
# 连接服务器
self.connect_server()
# 表示一封邮件,需要邮件主题

# 创建一个带附件的实例
message = MIMEMultipart()

# 附件内容,如文本文件,图片文件等

# 指定头部信息
att1["Content-Type"] = 'application/octet-stream' # 内容为二进制流

self.message.attach(att1)

# 注意:如果遇到发送失败的情况(提示远程主机拒接连接),这里要使用SMTP_SSL方法
smtpObj.connect(self.smtp_server)

# 发送的html格式的内容,只会留body标签中的内容(且不包含script标签)

过程中遇到的问题:
1.认证问题
解决方法:
在自己的QQ邮箱开启POP3和SMTP服务,得到授权码,填写正确的信息,重新进行认证。
