关于python：urllib2.HTTPError：HTTP错误403：禁止

urllib2.HTTPError: HTTP Error 403: Forbidden

我正在尝试使用python自动下载历史股票数据。我尝试打开的URL以CSV文件响应，但我无法使用urllib2打开。我之前在几个问题中已经尝试更改用户代理，我甚至尝试接受响应cookie，没有运气。你能帮忙吗？

注意：同样的方法适用于雅虎财经。

错误

File"C:\Python27\lib\urllib2.py", line 527, in http_error_default
raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) urllib2.HTTPError: HTTP Error 403: Forbidden

谢谢你的协助

req = urllib2.Request(site, headers=hdr)

try:
page = urllib2.urlopen(req)
except urllib2.HTTPError, e:
print e.fp.read()

content = page.read()
print content

实际上，它只适用于这一个额外的标题：

1	'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8',

NSE网站已经改变，旧的脚本对当前网站来说是半最优的。此代码段可以收集每日安全细节。详情包括符号，证券类型，前期收盘价，开盘价，高价，低价，平均价，交易数量，营业额，交易数量，可交割数量以及交割与交易的比率(以百分比表示)。这些方便地呈现为字典表格列表。

此外，这是相对模块化和随时可用的代码段。
