=head1 DESCRIPTION |
94
|
|
|
|
|
|
|
|
95
|
|
|
|
|
|
|
Let's face it: L<Dancer2>'s parameter-fetching keywords take so much typing |
96
|
|
|
|
|
|
|
to use! Why can't they be shorter? Well now, dear reader, they are! |
97
|
|
|
|
|
|
|
|
98
|
|
|
|
|
|
|
This module provides a little syntactic sugar to make getting query, route, |
99
|
|
|
|
|
|
|
and body parameters just a little bit quicker. Instead of writing these: |
100
|
|
|
|
|
|
|
|
101
|
|
|
|
|
|
|
query_parameters->get( ... ); |
102
|
|
|
|
|
|
|
query_parameters->get_all( ... ); |
103
|
|
|
|
|
|
|
query_parameters |
104
|
|
|
|
|
|
|
body_parameters->get( ... ); |
105
|
|
|
|
|
|
|
body_parameters->get_all( ... ); |
106
|
|
|
|
|
|
|
body_parameters |
107
|
|
|
|
|
|
|
route_parameters->get( ... ); |
108
|
|
|
|
|
|
|
route_parameters |
109
|
|
|
|
|
|
|
|
110
|
|
|
|
|
|
|
You can write just these: |
111
|
|
|
|
|
|
|
|
112
|
|
|
|
|
|
|
query_param( ... ); |
113
|
|
|
|
|
|
|
query_params( ... ); |
114
|
|
|
|
|
|
|
query_params |
115
|
|
|
|
|
|
|
body_param( ... ); |
116
|
|
|
|
|
|
|
body_params( ... ); |
117
|
|
|
|
|
|
|
body_params |
118
|
|
|
|
|
|
|
route_param( ... ); |
119
|
|
|
|
|
|
|
route_params |
120
|
|
|
|
|
|
|
|
121
|
|
|
|
|
|
|
That's about 25-50% less typing in many cases. You're welcome. |

This is the same as calling C<query_parameters-E<gt>get>. You must pass a |
128
|
|
|
|
|
|
|
parameter name to get the value of. |

132

|
|
|
|
|
|
If called without a parameter name, this is just like calling |
133
|
|
|
|
|
|
|
C<query_parameters>. It will return a L<Hash::MultiValue> object containing |
134
|
|
|
|
|
|
|
all of the query parameters that were passed. |
135
|
|
|
|
|
|
|
|
136
|
|
|
|
|
|
|
When called with a parameter name, this is the same as calling |
137
|
|
|
|
|
|
|
C<query_parameters-E<gt>get_all>. |

|

|
|
|
|
141
|
|
|
|
|
|
|
This is the equivalent of C<body_parameters-E<gt>get>. You must pass a |
142
|
|
|
|
|
|
|
parameter name to get the value of. |

145
|
|
|
|
|
|
|
|
146
|
|
|
|
|
|
|
When called without a parameter name, this is the same as calling |
147
|
|
|
|
|
|
|
C<body_parameters>. It will return a L<Hash::MultiValue> object containing |
148
|
|
|
|
|
|
|
all of the body parameters that were posted to your route. |
149
|
|
|
|
|
|
|
|
150
|
|
|
|
|
|
|
When called with a parameter name, this acts the same as calling |
151
|
|
|
|
|
|
|
C<body_parameters-E<gt>get_all>. |

154
|
|
|
|
|
|
|
|
155
|
|
|
|
|
|
|
This is the equivalent of C<route_parameters-E<gt>get>. You must pass a |
156
|
|
|
|
|
|
|
parameter name to get. |
157

=head2 route_params |
159
|
|
|
|
|
|
|
|
160
|
|
|
|
|
|
|
When called without a parameter name, this is the equivalent of calling |
161
|
|
|
|
|
|
|
C<route_parameters>. It will return a L<Hash::MultiValue> object containing |
162
|
|
|
|
|
|
|
all of the route parameters that were passed. |
163
|
|
|
|
|
|
|
|
164
|
|
|
|
|
|
|
Unlike C<query_params> and C<body_params>, you cannot assign multiple |
165
|
|
|
|
|
|
|
values to a single named parameter through route parameters in Dancer2. |
166
|
|
|
|
|
|
|
As such, you cannot pass a parameter to C<route_params> as you can with |
167
|
|
|
|
|
|
|
the other two methods - the underlying C<get_all> functionality for |
168
|
|
|
|
|
|
|
route parameters does not exist. |
