urllib2.HTTPError: HTTP Error 400: Bad Request

Question

简单地发起一个POST请求，但是报错了，麻烦大佬帮忙看一下

import sys
reload(sys)
sys.setdefaultencoding('utf8')

import urllib2
import urllib

import json
url = 'http://shuju.wdzj.com/plat-info-target.html'
data = urllib.urlencode({'type1': 19, 'type2': 20, 'status': 1, 'wdzjPlatId': 59})
request = urllib2.Request(url)
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor())    
response = opener.open(request,    data)
result = response.read()

报错如下：

Traceback (most recent call last):
