需求:

1、获取前十条科技要闻

2、通过邮件发送给指定收件人

3、定时发送

 

1、获取要闻,选的是新浪科技网https://tech.sina.com.cn/,爬取前十名要闻

import requests
from requests import exceptions
from urllib.request import urlopen
from bs4 import BeautifulSoup
import re

# 获取前十条科技新闻
def get_tech_news():
    # 获取网页文本
    resp = urlopen(https://tech.sina.com.cn/)
    # 使用爬虫工具BeautifulSoup查找需要的文本内容
    soup = BeautifulSoup(resp, html.parser)
    news = soup.find(ul, class_=rank-con)
    news_list = []
    for new in news:
        if len(new.string) > 5:
            news_list.append(new.string.replace( , ))
    # 组装邮件文本,<br>换行
    news_contents = f‘‘‘
    今日科技要闻<br>
    1、{news_list[0]}<br>
    2、{news_list[1]}<br>
    3、{news_list[2]}<br>
    4、{news_list[3]}<br>
    5、{news_list[4]}<br>
    6、{news_list[5]}<br>
    7、{news_list[6]}<br>
    8、{news_list[7]}<br>
    9、{news_list[8]}<br>
    10、{news_list[9]}<br>
    详情,请进入https://tech.sina.com.cn 查看
    ‘‘‘.replace(\t, ‘‘)
    print(news_contents)
    send_email("今日科技要闻", news_contents)

 

2、定义发送邮件函数,跟上次一样,同级目录需要config.yml配置文件

# config.yml配置文件
email:
    sender: mikasama007@163.com
    receiver: mikasama007@163.com
    smtpserver: smtp.163.com
    username: mikasama007
    password: 邮箱密码
import time
import yaml
import smtplib
import sys
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email.header import Header


def get_conf():
    with open ("config.yml", "r", encoding=utf-8) as f:
        cfg = f.read()
        dic = yaml.load(cfg)
        # print(type(dic))
        # print(dic)
        sender = dic[email][sender]
        receiver = dic[email][receiver]
        smtpserver = dic[email][smtpserver]
        username = dic[email][username]
        password = dic[email][password]
        # print(sender, receiver, smtpserver, username, password)
        return sender, receiver, smtpserver, username, password

def send_email(title, text):
    today = time.strftime(%Y.%m.%d,time.localtime(time.time()))
    sender, receiver, smtpserver, username, password = get_conf()
    # subject为邮件主题 text为邮件正文
    subject = "{}:{}".format(title, today)
    msg = MIMEText(text, html, utf-8)
    msg[Subject] = subject
    msg[From] = sender
    msg[To] = "".join(receiver)
    # smtp = smtplib.SMTP()
    # smtp.connect(smtpserver)
    # 变量名不能为stmp,改为server
    # windows上端口为25,linux上使用SMTP_SSL
    # server = smtplib.SMTP(smtpserver, 25)
    # https://blog.csdn.net/zekdot/article/details/81013176
    server = smtplib.SMTP_SSL(smtpserver, 465)
    server.set_debuglevel(0)
    server.login(username, password)
    server.sendmail(sender, receiver, msg.as_string())
    server.quit()

3、引入schedule库,定时发送邮件

import schedule

# 每天早上8点发送邮件通知
schedule.every().day.at("08:00").do(do_all_get_tech_news)

# 确保schedule一直运行
while True:
    schedule.run_pending()
    time.sleep(1)

4、丢服务器上去

运行python send_news.py

居然发不了邮件?换个地方就不行?

将登陆模式改为SSL即可:

server = smtplib.SMTP_SSL(smtpserver, 465)

修改后,可以正常发送邮件,cool!

但是这样可不行,ssh连接关闭,程序肯定会退出的,我们需要后台运行:

nohup python send_news.py &

查看下:

 

# root @ www in /home/cool_things/send_news [23:06:35] C:1
$ nohup python send_news.py &
[1] 24713

# root @ www in /home/cool_things/send_news [23:06:45] 
$ nohup: ignoring input and appending output to ‘nohup.out’


# root @ www in /home/cool_things/send_news [23:06:50] 
$ ps -ef | grep python
root       724     1  0 Apr01 ?        00:25:52 /usr/bin/python -Es /usr/sbin/tuned -l -P
root     10357     1  0 Apr01 ?        00:03:20 /usr/bin/python -Es /usr/sbin/firewalld
root     23391     1  0 Sep01 ?        00:10:10 python send_msg_to_wx.py
root     24713 21231  1 23:06 pts/1    00:00:00 python send_news.py

# root @ www in /home/cool_things/send_news [23:06:58] 
$ ps -ef | grep send_news
root     24713 21231  0 23:06 pts/1    00:00:00 python send_news.py

搞定,程序已经在后台运行,从明天开始,三爷每天早上8点就能收到每日要闻邮件了。
