想用urllib抓取上交所股票列表的xls下載鏈接，如下圖紅色小框：

#發現抓下來的xls只有報錯訊息：

#請問要怎樣才能把有內容的xls抓下來？

程式碼如下

from urllib import request
from datetime import datetime

# -*- coding:utf-8 -*-

url = 'http://query.sse.com.cn/security/stock/downloadStockListFile.do?' \
      'csrcCode=&stockCode=&areaName=&stockType=1'

myheaders = [('User - Agent', 'Mozilla/5.0 (Windows; U; Windows NT 5.2) AppleWebKit/525.13'
                              ' (KHTML, like Gecko) Version/3.1 Safari/525.13'),]

opener = request.build_opener()
opener.addheaders = myheaders
request.install_opener(opener)

local = "/Users/Mty/Downloads/data/" + str(datetime.now().date()) + " .xls"

request.urlretrieve(url, local)
