HTTP Forbidden Error when Downloading Historical Stock Data with urllib2

Error:

"urllib2.HTTPError: HTTP Error 403: Forbidden"

Initial Attempts:

After encountering this error while trying to download historical stock data, several troubleshooting steps were taken, including:

• Changing the user agent
• Accepting response cookies

However, these attempts were unsuccessful.

Solution:

To resolve the error, additional HTTP headers were added to the request. The following code demonstrates the updated approach:

import urllib2,cookielib

site= "http://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/getHistoricalData.jsp?symbol=JPASSOCIAT&fromDate=1-JAN-2012&toDate=1-AUG-2012&datePeriod=unselected&hiddDwnld=true"
hdr = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11',
       'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
       'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',
       'Accept-Encoding': 'none',
       'Accept-Language': 'en-US,en;q=0.8',
       'Connection': 'keep-alive'}

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

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

content = page.read()
print content

Explanation:

Adding the additional headers, particularly 'Accept', allowed the request to retrieve the CSV file without encountering the "HTTP Error 403: Forbidden" error.
