Question

Using httplib2 and urllib2, I'm trying to fetch pages from this url, but all of them didn't work out and ended up with this exception.

content = conn.request(uri="http://www.zdnet.co.kr/news/news_print.asp?artice_id=20110727092902")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/httplib2/__init__.py", line 1129, in request
    (response, content) = self._request(conn, authority, uri, request_uri, method, body, headers, redirections, cachekey)
  File "/usr/lib/python2.7/dist-packages/httplib2/__init__.py", line 901, in _request
    (response, content) = self._conn_request(conn, request_uri, method, body, headers)
  File "/usr/lib/python2.7/dist-packages/httplib2/__init__.py", line 871, in _conn_request
    response = conn.getresponse()
  File "/usr/lib/python2.7/httplib.py", line 1027, in getresponse
    response.begin()
  File "/usr/lib/python2.7/httplib.py", line 407, in begin
    version, status, reason = self._read_status()
  File "/usr/lib/python2.7/httplib.py", line 371, in _read_status
    raise BadStatusLine(line)

HTTP header was like this 

http://www.zdnet.co.kr/news/news_print.asp?artice_id=20110727092902

Any clue?

Solution

This works fine for me:

import urllib2

opener = urllib2.build_opener()

headers = {
  'User-Agent': 'Mozilla/5.0 (Windows NT 5.1; rv:10.0.1) Gecko/20100101 Firefox/10.0.1',
}

opener.addheaders = headers.items()
response = opener.open("http://www.zdnet.co.kr/news/news_print.asp?artice_id=20110727092902")

print response.headers
print response.read()

The website discards all requests that occur without a User-Agent string.

OTHER TIPS

For all the people that end up here with a similar problem after installing httplib2 0.8:

Version 0.8 has a regression with connection handling in relation with HTTP keep-alive. See the bug report: https://code.google.com/p/httplib2/issues/detail?id=250

There is a fix for this issue, but it has not been released so far. Until then just use httplib2 0.7.7.

In my code,when i use 

    from urllib2 import urlopen  
    content = urlopen(page).read()

the exception appears. However, when i use

    import urllib  
    content = urllib.urlopen(page).read()

everything is ok. Maybe it will help u.

Look like this webpage doesn't allow your user agent. You can change it like this:

>>> import urllib2
>>> user_agent = 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'
>>> headers = { 'User-Agent' : user_agent }
>>> r = urllib2.Request('http://www.zdnet.co.kr/news/news_print.asp?artice_id=20110727092902', headers=headers)
>>> fd = urllib2.urlopen(r)
>>> print fd[20:]
