NAME¶
AppConfig::CGI - Perl5 module for processing CGI script parameters.
SYNOPSIS¶
use AppConfig::CGI;
my $state = AppConfig::State->new(\%cfg);
my $cgi = AppConfig::CGI->new($state);
$cgi->parse($cgi_query);
$cgi->parse(); # looks for CGI query in environment
OVERVIEW¶
AppConfig::CGI is a Perl5 module which implements a CGI interface to AppConfig.
It examines the QUERY_STRING environment variable, or a string passed
explicitly by parameter, which represents the additional parameters passed to
a CGI query. This is then used to update variable values in an
AppConfig::State object accordingly.
AppConfig::CGI is distributed as part of the AppConfig bundle.
DESCRIPTION¶
USING THE AppConfig::CGI MODULE¶
To import and use the AppConfig::CGI module the following line should appear in
your Perl script:
use AppConfig::CGI;
AppConfig::CGI is used automatically if you use the AppConfig module and create
an AppConfig::CGI object through the
cgi() method. AppConfig::CGI is
implemented using object-oriented methods. A new AppConfig::CGI object is
created and initialised using the
new() method. This returns a
reference to a new AppConfig::CGI object. A reference to an AppConfig::State
object should be passed in as the first parameter:
my $state = AppConfig::State->new();
my $cgi = AppConfig::CGI->new($state);
This will create and return a reference to a new AppConfig::CGI object.
PARSING CGI QUERIES¶
The "parse()" method is used to parse a CGI query which can be
specified explicitly, or is automatically extracted from the
"QUERY_STRING" CGI environment variable. This currently limits the
module to only supporting the GET method.
See AppConfig for information about using the AppConfig::CGI module via the
cgi() method.
