python爬取英語學習資料併發送郵件

新建發送郵件類

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

class SendMail:

   def __init__(self):
       self.sender = '[email protected]'
       self.receivers = ['[email protected]','[email protected]']  # 接收郵件，可設置為你的QQ郵箱或者其他郵箱
       self.smtp_server = 'smtp.qq.com'
       self.smtp_pwd = 'xx'
       self.stmp_port = 25

   def sendMessage(self, title, msg):
       # 三個參數：第一個為文本內容，第二個 plain 設置文本格式，第三個 utf-8 設置編碼
       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')

爬取英語學習資料

比如爬取英語學習鏈接：http://www.hjenglish.com/new/c1020/，將當前頁文章爬取到併發送郵件到指定郵箱：
