邮件传输协议(SMTP)

如何验证 Email 地址：SMTP 协议入门教程

SSL

为Netscape所研发，用以保障在Internet上数据传输之安全，利用数据加密(Encryption)技术，可确保数据在网络上之传输过程中不会被截取及窃听。

SSL协议位于TCP/IP协议与各种应用层协议之间，为数据通讯提供安全支持。

以QQ邮箱为例子:开启smtp协议 和 一些设置

开启smtp协议 一些设置

1. [汉字编码报错] UnicodeEncodeError- 'ascii' codec can't encode characters in position 0-1- ordinal not in
2. python 出现socket.gaierror: [Errno 11004] getaddrinfo failed错误

import smtplib

mail = ''
authorization_code = ''
send_mail = ''
# 服务的设置
server = smtplib.SMTP_SSL('smtp.qq.com', 465)
# 登陆
server.login(mail, authorization_code)

# 发送信息
# 如果是汉字则
news = 'this is a news'

# 邮件的发送
server.sendmail(mail, send_mail, news)
# 退出
server.quit()

包装一下

import smtplib
from email.mime.text import MIMEText
mail = ''
authorization_code = ''
send_mail = ''
server = smtplib.SMTP_SSL('smtp.qq.com', 465)
# 登陆
server.login(mail, authorization_code)

# 发送信息
# 如果是汉字则
news = 'this is a news'

# 邮件的发送
server.sendmail(mail, send_mail, str(MIMEText(news)))
# 退出
server.quit()

设置发送者和接收者

import smtplib
from email.mime.text import MIMEText
mail = ''
authorization_code = ''
send_mail = ''
server = smtplib.SMTP_SSL('smtp.qq.com', 465)
# 登陆
server.login(mail, authorization_code)

# 发送信息
# 如果是汉字则
news = 'this is a news'
massage = MIMEText(news, 'plain', 'utf8')

# 设置主题
title = 'SMTP TEST'

# 设置邮件发送者和邮件接收者
massage['FROM'] = mail
massage['TO'] = send_mail

# 把主题加入到massage
massage['Subject'] = title


# 邮件的发送
server.sendmail(mail, send_mail, str(massage))
# 退出
server.quit()

1. Python_报错：SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape
2. pdf打不开的问题
3. ppt/word乱码的问题
