hello,

use the HEADERFUNCTION option to set a callback which is called when the
web server sends a reply.

note that 'connect() failed' is not a reply from the server. it's an
internal curl error which indicates that curl cannot connect to the
target web server. such errors are raised as exceptions by pycurl but
can be caught and transformed with regular string operations.

in addition, you can use getinfo() with HTTP_CODE as parameter to
extract the server response code (assuming that the server sends a
reply).

it's all shown in the code below:

--------------------------------------------------------

import sys, pycurl

## Callback function invoked when body data is ready
def body(buf):
    sys.stdout.write(buf)

## Callback function invoked when header data is ready
def header(buf):
    sys.stderr.write(buf)

c = pycurl.Curl()
c.setopt(pycurl.URL, 'http://curl.haxx.se/')
c.setopt(pycurl.WRITEFUNCTION, body)
c.setopt(pycurl.HEADERFUNCTION, header)
try:
    c.perform()
except pycurl.error, msg:
    errno, text = msg
    sys.stderr.write('Error (error number %d): %s\n' % (text, errno))
sys.stderr.write('HTTP status code: %d\n' % c.getinfo(pycurl.HTTP_CODE))
c.close()

--------------------------------------------------------

hope this helps,
