請務必每天早上8點將前十條科技要聞發給三爺

需求：

1、獲取前十條科技要聞

2、通過郵件發送給指定收件人

3、定時發送

 

1、獲取要聞，選的是新浪科技網https://tech.sina.com.cn/，爬取前十名要聞

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

# 獲取前十條科技新聞
def get_tech_news():
    # 獲取網頁文本
    resp = urlopen('https://tech.sina.com.cn/')
    # 使用爬蟲工具BeautifulSoup查找需要的文本內容
    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(' ', '，'))
    # 組裝郵件文本，<br>換行
    news_contents = f'''
    今日科技要聞<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>
    詳情，請進入https://tech.sina.com.cn 查看
    '''.replace('\t', '')
    print(news_contents)
    send_email("今日科技要聞", news_contents)

 

2、定義發送郵件函數，跟上次一樣，同級目錄需要config.yml配置文件

# config.yml配置文件
email:
    sender: '[e-mail]'
    receiver: '[e-mail]'
    smtpserver: 'smtp.163.com'
    username: 'mikasama007'
    password: '郵箱密碼'

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為郵件主題 text為郵件正文
    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)
    # 變量名不能為stmp，改為server
    # windows上端口為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庫，定時發送郵件

import schedule

# 每天早上8點發送郵件通知
schedule.every().day.at("08:00").do(do_all_get_tech_news)

# 確保schedule一直運行
while True:
    schedule.run_pending()
    time.sleep(1)

4、丟服務器上去

運行python send_news.py

居然發不了郵件？換個地方就不行？

將登陸模式改為SSL即可：

server = smtplib.SMTP_SSL(smtpserver, 465)

修改后，可以正常發送郵件，cool！

但是這樣可不行，ssh連接關閉，程序肯定會退出的，我們需要后台運行：

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，程序已經在后台運行，從明天開始，三爺每天早上8點就能收到每日要聞郵件了。
