项目需求，要求获得github的repo的api，以便可以提取repo的数据进行分析。研究了一天，终于解决了这个问题，虽然效率还是比较低下。

import re
import os

def GetUrl(num):
    str = os.popen("curl -G https://api.github.com/repositories?since=%d"%(num)).read()
    pattern = ‘"url"‘
    pattern1=‘repos‘
    urls=str.split(‘,\n‘)         
    for i in urls:
      if pattern in i and pattern1 in i:
           
#          text1=i.splite(‘:‘)
          text=re.compile(‘"(.*?)"‘).findall(i)[1]
          print text


if __name__==‘__main__‘:
    GetUrl(1000)

    其中num的值指的是页面的id，我们可以做一个循环，不断增大num的值，就可以无限提取repo。因为github的api对于流量是有限制的，所以这么做是一个可行的方法。
