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

问题描述

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 datarequest = urllib2.Request(url, data, headers) print requestresponse = urllib2.urlopen(request) page = response.read() print page

报错如下，
