用python3下载最新的ssr服务器地址：

2.py

import urllib.request
import sys


import time

timetag = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
print (timetag)

url = "https://github.com/Alvin9999/new-pac/wiki/ss%E5%85%8D%E8%B4%B9%E8%B4%A6%E5%8F%B7"
req = urllib.request.Request(url)
f = urllib.request.urlopen(req)
s = f.read()
s = s.decode('utf-8','ignore')

#print (s)

num = s.find('<p>ssr://')
print (num)

src = s[num:]
num_end = src.find('<p><strong>')

content = src[:num_end]
print(content)
mdir = sys.path[0]+'/'
file = open(mdir+'ssr.html','a',1,'utf-8')
file.write(timetag+"\n")
file.write(content)
file.close()

在centos服务器上，打开定时执行功能。每个小时的第一分钟执行一次。

vim /etc/crontab
