python爬取英语学习资料并发送邮件

新建发送邮件类

import smtplib
from email.mime.text import mimetext
from email.header import header

class sendmail:

   def __init__(self):
       self.sender = '[e-mail]'
       self.receivers = ['[e-mail]','[e-mail]']  # 接收邮件，可设置为你的qq邮箱或者其他邮箱
       self.smtp_server = 'smtp.qq.com'
       self.smtp_pwd = 'xx'
       self.stmp_port = 25

   def sendmessage(self, title, msg):
       # 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(msg, 'plain', 'utf-8')
       message['from'] = self.sender
       message['to'] = ';'.join(self.receivers)

       message['subject'] = header(title, 'utf-8')

       smtpobj = smtplib.smtp(self.smtp_server, self.stmp_port)
       smtpobj.starttls()
       smtpobj.login(self.sender, self.smtp_pwd)
       smtpobj.sendmail(self.sender, self.receivers, message.as_string())
       print('success')

爬取英语学习资料

比如爬取英语学习链接：http://www.hjenglish.com/new/c1020/，将当前页文章爬取到并发送邮件到指定邮箱：

        res.raise_for_status()
        page = beautifulsoup(res.text, 'lxml')
        res.close()
