python - urllib2.HTTPError: HTTP Error 400: Bad Request 求帮忙

Question

新手这里，简单的直接抓取一个页面也报错，帮忙看下

url = 'https://xueqiu.com/stock/f10/finmainindex.json'
user_agent = 'Mozilla/5.0'  
values = {'symbol' : 'SZ000001',  'page' : '1','size' : '1' }  
headers = { 'User-Agent' : user_agent }  
data = urllib.urlencode(values)  
print data
request = urllib2.Request(url, data, headers)  
print request
response = urllib2.urlopen(request)  
page = response.read() 
print page 

报错如下，

(flask)[root@centos7 xueqiu]# python xueqiu.py 
symbol=SZ000001&page=1&size=1
