# The hash %URIdef defines all the xCAT resources which can be access from Web Service.
# This script will be called when a https request with the URI started with /xcatws/ is sent to xCAT Web Service
# Inside this script:
# 1. The main body parses the URI and parameters
# 2. Base on the URI, go through the %URIdef to find the matched resource by the 'matcher' which is defined for each resource
# 3. Call the 'fhandler' which is defined in the resource to communicate with xcatd and get the xml response
# 3.1 The 'fhandler' generates the xml request base on the resource, parameters and http method 'GET|PUT|POST|DELETE', sends to xcatd and then get the xml response
# 4. Call the 'outhdler' which is defined in the resource to parse the xml response and translate it to JSON format
# 5. Output the http response to STDOUT
#
# Refer to the $URIdef{node}->{allnode} and $URIdef{node}->{nodeallattr} for your new created resource definition.

# Development notes:
# - added this line to /etc/httpd/conf/httpd.conf to hide the cgi-bin and .cgi extension in the uri:
# ScriptAlias /xcatws /var/www/cgi-bin/xcatws.cgi
# - also upgraded CGI to 3.52
# - If "Internal Server Error" is returned, look at /var/log/httpd/ssl_error_log
# - can run your cgi script from the cli: http://perldoc.perl.org/CGI.html#DEBUGGING
# This is how the parameters come in:
# GET: url parameters come $q->url_param. There is no put/post data.
# PUT: url parameters come $q->url_param. Put data comes in q->param(PUTDATA).
# POST: url parameters come $q->url_param. Post data comes in q->param(POSTDATA).
# DELETE: ??
# Notes from http://perldoc.perl.org/CGI.html:
# %params = $q->Vars; # same as $q->param() except put it in a hash
# @foo = split("\0",$params{'foo'});
# my $error = $q->cgi_error; #todo: check for errors that occurred while processing user input
# print $q->end_html; #todo: add the </body></html> tags
