Curl Object
===========
Curl objects have the following methods:
**close**\ () -> *None*
Corresponds to `curl_easy_cleanup`_ in libcurl. This method is
automatically called by pycurl when a Curl object no longer has any
references to it, but can also be called explicitly.
**perform**\ () -> *None*
Corresponds to `curl_easy_perform`_ in libcurl.
**reset**\ () -> *None*
Corresponds to `curl_easy_reset`_ in libcurl.
**setopt**\ (*option, value*) -> *None*
Corresponds to `curl_easy_setopt`_ in libcurl, where *option* is
specified with the ``CURLOPT_*`` constants in libcurl, except that the
``CURLOPT_``
prefix has been removed. (See below for exceptions.) The type for *value*
depends on the option, and can be either a string, integer, long integer,
file object, list, or function.
Example usage:
::
import pycurl
c = pycurl.Curl()
c.setopt(pycurl.URL, "http://www.python.org/")
c.setopt(pycurl.HTTPHEADER, ["Accept:"])
import StringIO
b = StringIO.StringIO()
c.setopt(pycurl.WRITEFUNCTION, b.write)
c.setopt(pycurl.FOLLOWLOCATION, 1)
c.setopt(pycurl.MAXREDIRS, 5)
c.perform()
print b.getvalue()
...
**getinfo**\ (*option*) -> *Result*
Corresponds to `curl_easy_getinfo`_ in libcurl, where *option* is the
same as the ``CURLINFO_*`` constants in libcurl, except that the ``CURLINFO_``
prefix
has been removed. (See below for exceptions.) *Result* contains an integer,
float or string, depending on which option is given. The ``getinfo`` method
should not be called unless ``perform`` has been called and finished.
Example usage:
::
import pycurl
c = pycurl.Curl()
c.setopt(pycurl.URL, "http://sf.net")
c.setopt(pycurl.FOLLOWLOCATION, 1)
c.perform()
print c.getinfo(pycurl.HTTP_CODE), c.getinfo(pycurl.EFFECTIVE_URL)
...
--> 200 "http://sourceforge.net/"
**pause**\ (*bitmask*) -> *None*
Corresponds to `curl_easy_pause`_ in libcurl. The argument should be
derived from the ``PAUSE_RECV``, ``PAUSE_SEND``, ``PAUSE_ALL`` and
``PAUSE_CONT`` constants.
**errstr**\ () -> *String*
Returns the internal libcurl error buffer of this handle as a string.
In order to distinguish between similarly-named CURLOPT and CURLINFO
constants, some have ``OPT_`` and ``INFO_`` prefixes. These are
``INFO_FILETIME``, ``OPT_FILETIME``, ``INFO_COOKIELIST`` (but ``setopt`` uses
``COOKIELIST``!), ``INFO_CERTINFO``, and ``OPT_CERTINFO``.
The value returned by ``getinfo(INFO_CERTINFO)`` is a list with one element
per certificate in the chain, starting with the leaf; each element is a
sequence of ``(``*key*``, ``*value*``)`` tuples.
