Python 2.7_发送简书关注的专题作者最新一篇文章及连接到邮件_20161218

最近看简书文章关注了几个专题作者,写的文章都不错,对爬虫和数据分析都写的挺好,因此想到能不能获取最新的文章推送到Ipad网易邮箱大师。邮件发送代码封装成一个函数,从廖雪峰大神那里学的

网页源码获取和解析获取文章标题和url依然是用到的requests和BeautifulSoup4 模块 也封装成一个函数。

#coding: utf-8
import sys
import requests
from bs4 import BeautifulSoup as bs
import smtplib
import datetime
from email.mime.text import MIMEText
from email.header import Header
from email.utils import parseaddr, formataddr
#系统编码置为'utf-8'
reload(sys)
sys.setdefaultencoding('utf-8')

#简书作者专题入口
rooturl='http://www.jianshu.com/notebooks/4204686/latest'
#获取网页源代码 并用bs4解析 返回soup对象
def gethtml(url):
    res=requests.get(url)
    res.encoding='utf-8'
    html=res.text
    soup=bs(html,'html.parser')
    return soup
#调用gethtml()函数获取网页soup对象 对网页进行解析 参数都是url
def sendmail(url):
    soup=gethtml(url)
    catename =  soup.select('h3.title a')[0].text
    titlename = soup.select('h4.title a')[0].text
    titleurl = 'http://www.jianshu.com' + soup.select('h4.title a')[0]['href']
    sender = '发件人邮箱'
    receiver = '收件人邮箱'
    subject = 'python email test'
    smtpserver = '发件人邮箱smtp服务器'
    username = '发件人邮箱'
    password = '发件人邮箱密码'
    date=datetime.date.today()
    def _format_addr(s):
        name, addr = parseaddr(s)
        return formataddr((
            Header(name, 'utf-8').encode(),
            addr.encode('utf-8') if isinstance(addr, unicode) else addr))
    msg = MIMEText('''

    文章链接:%s
        ''' % (date,catename,titlename,titleurl), 'plain', 'utf-8')
    msg['From'] = _format_addr(u'简书App <%s>' % sender)
    msg['To'] = _format_addr(u'yourself~ <%s>' % receiver)
    msg['Subject'] = Header(u'简书作者最新文章', 'utf-8').encode()
    smtp = smtplib.SMTP('smtp.163.com',25)
    smtp.login(username, password)
    smtp.sendmail(sender, receiver, msg.as_string())
    smtp.quit()
print sendmail(rooturl)
