Mojo::Parameters - Parameters
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";
Mojo::Parameters is a container for form parameters used by Mojo::URL, based on RFC 3986 <https://tools.ietf.org/html/rfc3986> and the HTML Living Standard <https://html.spec.whatwg.org>.
Mojo::Parameters implements the following attributes.
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);
Mojo::Parameters inherits all methods from Mojo::Base and implements the following new ones.
$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);
my $params2 = $params->clone;
Return a new Mojo::Parameters object cloned from these parameters.
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];
$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);
my $names = $params->names;
Return an array reference with all parameter names.
# Names of all parameters say for @{$params->names};
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.
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([]);
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.
$params = $params->parse('foo=b%3Bar&baz=23');
Parse parameters.
$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');
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];
my $str = $params->to_string;
Turn parameters into a string.
# "foo=bar&baz=23" Mojo::Parameters->new->pairs([foo => 'bar', baz => 23])->to_string;
Mojo::Parameters overloads the following operators.
my @pairs = @$params;
Alias for "pairs". Note that this will normalize the parameters.
say $params->[0]; say for @$params;
my $bool = !!$params;
Always true.
my $str = "$params";
Alias for "to_string".
