Python抓取数据的几种方式

1. import urllib.request
   response = urllib.request.urlopen('http://python.org/')
   html = response.read()

2. import urllib.request
   req = urllib.request.Request('http://python.org/')
   response = urllib.request.urlopen(req)
   the_page = response.read()

3. from urllib import request, parse
   post_data = parse.urlencode({'id':45,'renewalDate':'2029-11-06 00:00:00.000'}).encode()
   req = request.Request('http://a.com/financial/api/FinancialCredit/Renew', data=post_data) # this will make the method "POST"
   resp = request.urlopen(req)
   print(resp.read())
