DESCRIPTION

The pan.afapi module defines the PanAFapi class, which provides an interface to the AutoFocus API.

PanAFapi provides an interface to all AutoFocus API requests:

Request PanAFApi Method API Resource URI
Search samples samples_search() /samples/search/
Get samples results samples_search_results() /samples/results/
Search sessions sessions_search() /sessions/search/
Get sessions results sessions_search_results() /sessions/results/
Get histogram of sessions sessions_histogram_search() /sessions/histogram/search/
Get histogram results sessions_histogram_results() /sessions/histogram/results/
Get aggregate of sessions sessions_aggregate_search() /sessions/aggregate/search/
Get aggregate results sessions_aggregate_results() /sessions/aggregate/results/
Search top tags top_tags_search() /top-tags/search/
Get top tags results top_tags_results() /top-tags/results/
Search tags tags() /tags/
Get tag tag() /tag/
Get session session() /session/
Get sample analysis sample_analysis() /sample/{id}/analysis
Export list export() /export/

In addition, convenience methods are provided for the search/results requests to perform the search and provide the results when the search is completed:

pan.afapi Constructor, Response object and Exception Class

class pan.afapi.PanAFapi()

class pan.afapi.PanAFapi(api_version=None,
                         panrc_tag=None,
                         hostname=None,

                         sleeper=None)
api_version

API version as a string in the form vmajor.minor or major.minor (e.g., v1.0). The API version is used to determine the PanAFapi class implementation to use.

The default API version is DEFAULT_API_VERSION.

api_version is verified and the class attribute is set to an instance of the _ApiVersion class (defined below).

panrc_tag
.panrc tagname.
hostname

URI hostname used in API requests. This can also be specified in a .panrc file using the hostname varname.

The default is autofocus.paloaltonetworks.com.

api_key
apiKey argument used in API requests. This can also be specified in a .panrc file using the api_key varname.
timeout
The HTTP connect timeout in seconds.
verify_cert

Specify if SSL server certificate verification is performed.

The default is to verify the server certificate.

sleeper

A class definition used to sleep between the search request, and each results request in the search/results convenience methods.

The default is PanAFapi._Sleeper.

exception pan.afapi.PanAFapiError

Exception raised by the PanAFapi class when an error occurs. The string representation of an instance of this exception will contain a user-friendly error message.

class pan.afapi.PanAFapiRequest()

The results of a request are returned in a PanAFapiRequest object.

pan.afapi.PanAFapiRequest Class Attributes and Methods

Attribute Description

Sample Usage

import pan.afapi

try:
    afapi = pan.afapi.PanAFapi(panrc_tag='autofocus')
except pan.afapi.PanAFapiError as e:
    print('pan.afapi.PanAFapi:', e, file=sys.stderr)
    sys.exit(1)

print('api_version: %s, 0x%06x' %
      (afapi.api_version, afapi.api_version))

Debugging and Logging

The Python standard library logging module is used to log debug output; by default no debug output is logged.

In order to obtain debug output the logging module must be configured: the logging level must be set to one of DEBUG1, DEBUG2, or DEBUG3 and a handler must be configured. DEBUG1 enables basic debugging output and DEBUG2 and DEBUG3 specify increasing levels of debug output.

For example, to configure debug output to stderr:

import logging

if options['debug']:
    logger = logging.getLogger()
    if options['debug'] == 3:
        logger.setLevel(pan.afapi.DEBUG3)
    elif options['debug'] == 2:
        logger.setLevel(pan.afapi.DEBUG2)
    elif options['debug'] == 1:
        logger.setLevel(pan.afapi.DEBUG1)

    handler = logging.StreamHandler()
    logger.addHandler(handler)

FILES

.panrc
.panrc file

EXAMPLES

The panafapi.py command line program calls each available PanAFapi method and can be reviewed for sample usage.
