spending some time studying pycurl and libcurl documentation, i still can't find a (simple) way, how to get HTTP status message (reason-phrase) in pycurl.
status code is easy:
import pycurl
import cStringIO
curl = pycurl.Curl()
buff = cStringIO.StringIO()
curl.setopt(pycurl.URL, 'http://example.org')
curl.setopt(pycurl.WRITEFUNCTION, buff.write)
curl.perform()
print "status code: %s" % curl.getinfo(pycurl.HTTP_CODE)
# -> 200
# print "status message: %s" % ???
# -> "OK"
i've found a solution myself, which does what i need, but could be more robust (works for HTTP).
it's based on a fact that captured headers obtained by pycurl.HEADERFUNCTION include the status line.
import pycurl
import cStringIO
import re
curl = pycurl.Curl()
buff = cStringIO.StringIO()
hdr = cStringIO.StringIO()
curl.setopt(pycurl.URL, 'http://example.org')
curl.setopt(pycurl.WRITEFUNCTION, buff.write)
curl.setopt(pycurl.HEADERFUNCTION, hdr.write)
curl.perform()
print "status code: %s" % curl.getinfo(pycurl.HTTP_CODE)
# -> 200
status_line = hdr.getvalue().splitlines()[0]
m = re.match(r'HTTP\/\S*\s*\d+\s*(.*?)\s*$', status_line)
if m:
status_message = m.groups(1)
else:
status_message = ''
print "status message: %s" % status_message
# -> "OK"
This is an old thread but I got here looking for similar information. If it is just the status code you're looking for, such as 200, 404, 500 etc. then just do:
your_curl_handle.getinfo(pycurl.RESPONSE_CODE)
which should return a numerical status code :)
pycurl.error: cannot invoke getinfo() - no curl handle error.I think that you can use human_curl library to create you code simple.
>>> import human_curl as hurl
>>> r = hurl.get('http://example.org')
>>> print r.status_code
200
Full documentation on human_curl you can get on https://github.com/Lispython/human_curl
If you only want the code, you can do, and assuming your pycurl.Curl() instance is called curl (ie. curl = pycurl.Curl()), you can do
curl.getinfo(pycurl.RESPONSE_CODE)
curl.getinfo(pycurl.HTTP_CODE)
But the nice way in my opinion is to parse the header yourself instead of letting libraries spoon-feed you everything.
Try BaseHTTPServer.BaseHTTPRequestHandler.responses, it should contain an errorcode dictionnary as explained in this page.
hope this helps.
