    这是cookie。。不过python的requests模块会自动管理cookie。 只需要先get那个网站一下就好了。

主要是抓到

1. Form Dataview sourceview URL encoded
   1. worksid:
      ###

里面的数据。。

1. Request
2. URL:
   http://musicman.migu.cn/activity/ccontent/voteWorks.do
3. Request Method:
   POST
4. Status Code:
   200 OK

目标 URL 跟方法是post。。然后没了

import requests,time
i = 0
data={"worksid":"###"}
s = requests.session()
s.get('http://musicman.migu.cn/activity/ccontent/queryWorksInfo.do?worksid=1850')
while i < 10 :
    i=i+1
    z = s.post('http://musicman.migu.cn/activity/ccontent/voteWorks.do',data)
    print z.text

然后就没了。。不过只是试验下。。

下面用urllib2,跟urllib模块重写了下。。

import urllib,cookielib
import urllib2
import json

cj=cookielib.CookieJar()
opener=urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
urllib2.install_opener(opener)

for ip in range(23,24):
    opener.open('http://musicman.migu.cn/activity/ccontent/queryWorksInfo.do?worksid=####')

    req=urllib2.Request('http://musicman.migu.cn/activity/ccontent/voteWorks.do')
    data={"worksid":"####"}
    ipAddress="192.168.4."+str(ip)
    #headers = {'X-Forwarded-For':ipAddress,'User-Agent':'Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko/20100101 Firefox/11.0'}
    req.add_header('Content-Type','application/x-www-form-urlencoded')
    req.add_header('X-Forwarded-For',ipAddress)
    req.add_header('User-Agent','Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko/20100101 Firefox/11.0')
    for i in range(10):
        k=opener.open("http://musicman.migu.cn/activity/ccontent/voteWorks.do",urllib.urlencode(data))
        print k.read()
