NAME
OCS::Client - simple interface to OCS's SOAP API
VERSION
version 0.013
SYNOPSIS
use OCS::Client;
my $ocs = OCS::Client->new('https://ocs.example.com', 'user', 'passwd');
my @computers = $ocs->get_computers_V1(
id => 123456,
checksum => OCS::Client::HARDWARE | OCS::Client::SOFTWARE,
);
%OCS::Client::ACCOUNT_INFO = (
3 => 'UA',
4 => 'Room',
5 => 'Onwner',
);
my $next_computer = $ocs->computer_iterator(asking_for => 'META');
while (my $meta = $next_computer->()) {
# ...
my $description = OCS::Client::prune($meta);
}DESCRIPTION
OCS is a technical management solution of IT assets. It's home page is https://www.ocsinventory-ng.org/.
This module implements a thin Object Oriented wrapper around OCS's SOAP API, which is somewhat specified in https://wiki.ocsinventory-ng.org/index.php/Developers:Web_services. (This version is known to work against OCS 2.0.1.)
VARIABLES
%ACCOUNT_INFO
The get_computers_V1 method returns administrative information about each computer in the ACCOUNTINFO tag. This information is specific to the OCS instance. Unfortunately there's no way to grok this information programatically from the server, but you may register the mapping from the ACCOUNTINFO_ID to a descriptive name directly in this hash.
You can see which administrative information is registered in the server by going to its web interface, clicking the 'Administrative Data' icon and the 'download' link to download a CSV file containing the name ('Wording' column) and ID ('MODIF' column) of every information.
This information is used by the prune method below.
METHODS
new OCSURL, USER, PASSWD [, <SOAP::Lite arguments>]
The OCS::Client constructor requires three arguments. OCSURL is OCS's base URL from which will be constructed it's SOAP URL. USER and PASSWD are the credentials that will be used to authenticate into OCS. Any other arguments will be passed to the SOAP::Lite object that will be created to talk to OCS.
get_computers_V1 REQUEST-MAP
This method allows for querying inventoried computers.
The REQUEST-MAP is a key-value list of information that is used to construct the XML request structure defined in the OCS documentation (see link above). Any key-value pair passed to the method is appended to the following default list:
engine => 'FIRST',
asking_for => 'INVENTORY',
checksum => 0x01FFFF,
wanted => 0x000003,
offset => 0,The complete list is used to initialize a hash from which the XML structure is built. Hence, you can override any one of the default values by respecifying it.
The method returns a list of hashes. Each hash represents a computer as a data structure that is converted from its XML original representation into a Perl data structure by the XML::Simple::XMLin function.
computer_iterator REQUEST-MAP
This method returns a closure that you can use to fetch the computers one by one until there is no more. It's usefull because the server usually has a limit to the maximum number of computers that get_computers_V1 can return at once. See an example of its usage in the SYNOPSIS above.
prune COMPUTER
This class method gets a COMPUTER description, as returned by the get_computer_V1 method, and simplifies it by deleting and converting some not so important information. It returns the simplified data structure.
Its original motivation was to get rid of unimportant information and turn it into the barest minimum that I wanted to save in a text file (after converting it into JSON) that I kept under version control. Without pruning the repository became unecessarily big and there were lots of frequently changing information that was uninportant to track.
Note that it tries to convert the custom field names by using the %ACCOUNT_INFO hash.
