python发送邮件

1.利用python脚本发送正文为文本的邮件

import smtplib
from email.mime.text import MIMEText
# 构建邮件头
from email.header import Header
class SendFile:
    def send_file(self,from_address,to_address,password,From,To):
        msg = MIMEText('使用python发送邮件测试', 'plain', 'utf-8')#邮件正文,文本格式
     
        # 邮件头信息
        msg['From'] = Header(From)  # 发送者
        msg['To'] = Header(To)  # 接收者
        subject = 'Python SMTP 邮件测试'
        msg['Subject'] = Header(subject, 'utf-8')  # 邮件主题


        smtobj = smtplib.SMTP_SSL('smtp.qq.com')
        smtobj.connect('smtp.qq.com', 465)#连接（connect）指定服务器
        smtobj.login(from_address, password)#登录，需要：登录邮箱和授权码
        smtobj.sendmail(from_address,to_address,msg.as_string())#发邮件
        print('邮件发送成功')
#       #关闭服务器
        smtobj.quit()

2.利用python脚本发送正文为html的邮件

import smtplib
from email.mime.text import MIMEText
# 构建邮件头
from email.header import Header
class SendFile:
    def send_file(self,from_address,to_address,password,From,To):
        
        msg = MIMEText('使用python发送邮件测试', 'HTML', 'utf-8')#html格式
        # 邮件头信息
        msg['From'] = Header(From)  # 发送者
        msg['To'] = Header(To)  # 接收者
        subject = 'Python SMTP 邮件测试'
        msg['Subject'] = Header(subject, 'utf-8')  # 邮件主题


        smtobj = smtplib.SMTP_SSL('smtp.qq.com')
        smtobj.connect('smtp.qq.com', 465)#连接（connect）指定服务器
        smtobj.login(from_address, password)#登录，需要：登录邮箱和授权码
        smtobj.sendmail(from_address,to_address,msg.as_string())#发邮件
        print('邮件发送成功')
#       #关闭服务器
        smtobj.quit()

3.利用python脚本发送带有附件的邮件

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
# 构建邮件头
from email.header import Header
class SendFile:
    def send_file(self,from_address,to_address,password,From,To):
        msg = MIMEText('使用python发送邮件测试', 'plain', 'utf-8')#邮件正文,文本格式
        #msg = MIMEText('使用python发送邮件测试', 'HTML', 'utf-8')#html格式
        # 邮件头信息
        msg['From'] = Header(From)  # 发送者
        msg['To'] = Header(To)  # 接收者
        subject = 'Python SMTP 邮件测试'
        msg['Subject'] = Header(subject, 'utf-8')  # 邮件主题

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

        # 构造附件1，传送当前目录下的 test1.txt 文件
        att1 = MIMEText(open('test1.txt', 'rb').read(), 'base64', 'utf-8')
        att1["Content-Type"] = 'application/octet-stream'
        # 这里的filename可以任意写，写什么名字，邮件中显示什么名字
        att1["Content-Disposition"] = 'attachment; filename="test1.txt"'
        msg.attach(att1)

        smtobj = smtplib.SMTP_SSL('smtp.qq.com')
        smtobj.connect('smtp.qq.com', 465)#连接（connect）指定服务器
        smtobj.login(from_address, password)#登录，需要：登录邮箱和授权码
        smtobj.sendmail(from_address,to_address,msg.as_string())#发邮件
        print('邮件发送成功')
#       #关闭服务器
        smtobj.quit()
