Python3 SMTP发送邮件

Python创建 SMTP 对象语法如下：

import smtplib

smtpObj = smtplib.SMTP( [host [, port [, local_hostname]]] )

参数说明：

host: SMTP 服务器主机。你可以指定主机的ip地址或者域名如:runoob.com，这个是可选参数。
port: 如果你提供了 host 参数, 你需要指定 SMTP 服务使用的端口号，一般情况下SMTP端口号为25。
local_hostname: 如果SMTP在你的本机上，你只需要指定服务器地址为 localhost 即可。

这里要注意一下第三个参数，msg是字符串，表示邮件。我们知道邮件一般由标题，发信人，收件人，邮件内容，附件等构成，发送邮件的时候，要注意msg的格式（message.as_string()）。这个格式就是smtp协议中定义的格式。

标准邮件需要三个头部信息： From, To, 和 Subject ，每个信息直接使用空行分割。

文本实例

import smtplib
from email.mime.text import MIMEText
from email.header import Header

# 第三方 SMTP 服务
mailHost = "smtp.qq.com"
mailUser = "576****[email protected]"
mailPass = "**************"

sender = "576****[email protected]"       # qq邮箱代发邮箱需要和登陆邮箱一致
receivers = ['292***[email protected]']

# 三个参数：第一个为文本内容，第二个 plain 设置文本格式，第三个 utf-8 设置编码
message = MIMEText("Geng的邮箱测试", "plain", "utf-8") # 邮件内容


message['From'] = Header("geng", 'utf-8')
message['To'] = Header('Eappo', 'utf-8')
message['Subject'] = Header('测试内容，脚本小子技术宅！', 'utf-8')

try:
    smtpObj = smtplib.SMTP() # 创建对象
    smtpObj.connect(mailHost, 25) #连接服务器与端口
    smtpObj.login(mailUser, mailPass) # 登陆
    smtpObj.sendmail(sender, receivers, message.as_string()) # 发送
    print("sucess")
except:
    print("failure")

HTML邮件实例

将MIMEText()函数内的内容进行修改即可：

mailmsg = """
<p>这是百度链接</p>
<p><a href = 'www.baidu.com'>百度一下</a></p>
"""
# message = MIMEText("Geng的邮箱测试", "plain", "utf-8")
message = MIMEText(mailmsg, "html", "utf-8")

from email.header import Header

# 第三方 SMTP 服务
mailHost = "smtp.qq.com"
mailUser = "576****[email protected]"
mailPass = "**************"

sender = "576****[email protected]"       # qq邮箱代发邮箱需要和登陆邮箱一致
receivers = ['292***[email protected]']



#邮件正文内容
message = MIMEMultipart() # 多内容
message.attach(MIMEText('Geng的邮箱测试', 'plain', 'utf-8'))

# 构造附件，传送当前目录下的 text.txt 文件
att = MIMEText(open('text.txt','rb').read(), 'base64', 'utf-8')
att['Content-Type'] = "application/octet-stream"
att['Content-Disposition'] = "attachment; filename = 'text.txt'"
message.attach(att)


message['From'] = Header("geng", 'utf-8')
message['To'] = Header('Eappo', 'utf-8')
message['Subject'] = Header('测试内容，脚本小子技术宅！', 'utf-8')

try:
    smtpObj = smtplib.SMTP()
    smtpObj.connect(mailHost, 25)
    smtpObj.login(mailUser, mailPass)
    smtpObj.sendmail(sender, receivers, message.as_string())
    print("sucess")
except:
    print("failure")
