爬取数据并发送邮件

当爬取数据后，有时候我们需要发送邮件进行通知，这时可以使用邮件自动发送的方式，当检测到文章更新时，自动抓取并发送。

当自己使用时，只需要把Mailhelper()类中的用户名和密码换为自己的，然后，调用send_mail(self, to_list, sub, content)就可以直接使用。

import requests
import smtplib
from email.mime.text import MIMEText
from bs4 import BeautifulSoup

class Mailhelper():
    def __init__(self):
        self.mail_host = "smtp.126.com"
        self.mail_user = "xxxxxx@126.com"
        self.mail_pass = 'xxxxxxx'
        self.port = '25'

    def send_mail(self, to_list, sub, content):
        me = "Mail Sender" + "<"+ self.mail_user + ">"
        msg = MIMEText(content, _subtype='plain', _charset='utf-8')
        msg['Subject'] = sub
        msg['From'] = me
        msg['To'] = ";".join(to_list)
        try:
            server = smtplib.SMTP(self.mail_host,self.port)
            server.connect(self.mail_host) 
            server.login(self.mail_user,self.mail_pass)
            server.sendmail(me, to_list, msg.as_string())
            server.close()
            print('Done')
        except Exception as e:
            print(str(e))
            return False


if __name__ == '__main__':
    mailto_list=['xxxxxx@126.com']
    helper = Mailhelper()

    url = "http://www.getrandomthings.com"
    Soup = BeautifulSoup(requests.get(url).text, 'lxml')
    prefixs = Soup.select('a')
    textr = []
    for prefix in prefixs:
        textr.append(prefix.get_text())
    textresult = ' '.join(textr)
    helper.send_mail(mailto_list, textresult[:17], textresult)
