URL = ""
URLCookie = ""

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

### 将cookie放在请求头中
opener.addheaders = [("user-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36"), ("cookie", URLCookie)]

### 提交的数据
postValues = {}
postData = urllib.urlencode(postValues)

### 访问URL
try:
    fileObject = opener.open(URL, postData)
except:
    print "error: open() error"

print fileObject.read()
