Re^3: Dancer2 parameters understanding and usage

[1nickt]

Just to be clear about route parameters. You can define any part of a URL path as a parameter. You don't need a 'static' part to prefix a param, although a lot of apps, particularly REST APIs, do that. You can also use route and query (and even body) params together. For example:

get '/foo/:name/bar/:age/:occupation' => sub {
    return '<pre>'.Dumper({ params }).'</pre>';
};

If the user requests the following URL:

http://localhost:5000/foo/Discipulus/bar/42/student?country=Eataly&cit
+y=Roma

The app displays in the browser:

<pre>$VAR1 = {
          'name' => 'Discipulus',
          'age' => '42',
          'city' => 'Roma',
          'occupation' => 'student',
          'country' => 'Eataly'
        };
</pre>
