NAME
Mojo::Parameters - Parameters
SYNOPSIS
use Mojo::Parameters;
# Parse
my $params = Mojo::Parameters->new('foo=bar&baz=23');
say $params->param('baz');
# Build
my $params = Mojo::Parameters->new(foo => 'bar', baz => 23);
push @$params, i => '♥ mojolicious';
say "$params";
DESCRIPTION
Mojo::Parameters is a container for form parameters used by Mojo::URL and based on RFC 3986 as well as the HTML Living Standard.
ATTRIBUTES
Mojo::Parameters implements the following attributes.
charset
my $charset = $params->charset;
$params = $params->charset('UTF-8');
Charset used for encoding and decoding parameters, defaults to UTF-8
.
# Disable encoding and decoding
$params->charset(undef);
METHODS
Mojo::Parameters inherits all methods from Mojo::Base and implements the following new ones.
append
$params = $params->append(foo => 'ba&r');
$params = $params->append(foo => ['ba&r', 'baz']);
$params = $params->append(foo => ['bar', 'baz'], bar => 23);
Append parameters. Note that this method will normalize the parameters.
# "foo=bar&foo=baz"
Mojo::Parameters->new('foo=bar')->append(foo => 'baz');
# "foo=bar&foo=baz&foo=yada"
Mojo::Parameters->new('foo=bar')->append(foo => ['baz', 'yada']);
# "foo=bar&foo=baz&foo=yada&bar=23"
Mojo::Parameters->new('foo=bar')->append(foo => ['baz', 'yada'], bar => 23);
clone
my $params2 = $params->clone;
Clone parameters.
merge
$params = $params->merge(Mojo::Parameters->new(foo => 'b&ar', baz => 23));
Merge Mojo::Parameters objects. Note that this method will normalize the parameters.
new
my $params = Mojo::Parameters->new;
my $params = Mojo::Parameters->new('foo=b%3Bar&baz=23');
my $params = Mojo::Parameters->new(foo => 'b&ar');
my $params = Mojo::Parameters->new(foo => ['ba&r', 'baz']);
my $params = Mojo::Parameters->new(foo => ['bar', 'baz'], bar => 23);
Construct a new Mojo::Parameters object and "parse" parameters if necessary.
param
my @names = $params->param;
my $foo = $params->param('foo');
my @foo = $params->param('foo');
my ($foo, $bar) = $params->param(['foo', 'bar']);
$params = $params->param(foo => 'ba&r');
$params = $params->param(foo => qw(ba&r baz));
$params = $params->param(foo => ['ba;r', 'baz']);
Check and replace parameter value. Be aware that if you request a parameter by name in scalar context, you will receive only the first value for that parameter, if there are multiple values for that name. In list context you will receive all of the values for that name. Note that this method will normalize the parameters.
params
my $array = $params->params;
$params = $params->params([foo => 'b&ar', baz => 23]);
Parsed parameters. Note that this method will normalize the parameters.
parse
$params = $params->parse('foo=b%3Bar&baz=23');
Parse parameters.
remove
$params = $params->remove('foo');
Remove parameters. Note that this method will normalize the parameters.
# "bar=yada"
Mojo::Parameters->new('foo=bar&foo=baz&bar=yada')->remove('foo');
to_hash
my $hash = $params->to_hash;
Turn parameters into a hash reference. Note that this method will normalize the parameters.
# "baz"
Mojo::Parameters->new('foo=bar&foo=baz')->to_hash->{foo}[1];
to_string
my $str = $params->to_string;
Turn parameters into a string.
OPERATORS
Mojo::Parameters overloads the following operators.
array
my @params = @$params;
Alias for "params". Note that this will normalize the parameters.
say $params->[0];
say for @$params;
bool
my $bool = !!$params;
Always true.
stringify
my $str = "$params";
Alias for "to_string".
