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, based on RFC 3986 and 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);
$params = $params->append(Mojo::Parameters->new);Append parameters. Note that this method will normalize the parameters.
# "foo=bar&foo=baz"
Mojo::Parameters->new('foo=bar')->append(Mojo::Parameters->new('foo=baz'));
# "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;Return a new Mojo::Parameters object cloned from these parameters.
every_param
my $values = $params->every_param('foo');Similar to "param", but returns all values sharing the same name as an array reference. Note that this method will normalize the parameters.
# Get first value
say $params->every_param('foo')->[0];merge
$params = $params->merge(foo => 'ba&r');
$params = $params->merge(foo => ['ba&r', 'baz']);
$params = $params->merge(foo => ['bar', 'baz'], bar => 23);
$params = $params->merge(Mojo::Parameters->new);Merge parameters. Note that this method will normalize the parameters.
# "foo=baz"
Mojo::Parameters->new('foo=bar')->merge(Mojo::Parameters->new('foo=baz'));
# "yada=yada&foo=baz"
Mojo::Parameters->new('foo=bar&yada=yada')->merge(foo => 'baz');
# "yada=yada"
Mojo::Parameters->new('foo=bar&yada=yada')->merge(foo => undef);names
my $names = $params->names;Return an array reference with all parameter names.
# Names of all parameters
say for @{$params->names};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.
pairs
my $array = $params->pairs;
$params = $params->pairs([foo => 'b&ar', baz => 23]);Parsed parameter pairs. Note that this method will normalize the parameters.
# Remove all parameters
$params->pairs([]);param
my $value = $params->param('foo');
$params = $params->param(foo => 'ba&r');
$params = $params->param(foo => qw(ba&r baz));
$params = $params->param(foo => ['ba;r', 'baz']);Access parameter values. If there are multiple values sharing the same name, and you want to access more than just the last one, you can use "every_param". 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 = $params->to_string;Turn parameters into a string.
# "foo=bar&baz=23"
Mojo::Parameters->new->pairs([foo => 'bar', baz => 23])->to_string;OPERATORS
Mojo::Parameters overloads the following operators.
array
my @pairs = @$params;Alias for "pairs". 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".
