OVERVIEW

It is possible to protect your API: You can either use a ``Custom route'' or an ``Around action hook''. Both can serve the same purpose, but the around action hook can be customized for every API resource.

TUTORIAL

Around action hook

The "x-mojo-around-action" value is optional, but can hold the name of a method to call, which wraps around the autogenerated action which does input and output validation. This means that any data sent to the server is not yet converted into $input to your action.

Here is an example method which match the "x-mojo-around-action" from ``Swagger specification'', "MyApp::authenticate_api_request":

  package MyApp;
  sub authenticate_api_request {
    my ($next, $c, $action_spec) = @_;
    # Go to the action if the Authorization header is valid
    return $next->($c) if $c->req->headers->authorization eq "s3cret!";
    # ...or render an error if not
    return $c->render_swagger(
      {errors => [{message => "Invalid authorization key", path => "/"}]},
      {},
      401
    );
  }

"x-mojo-around-action" is also inherited from most levels, meaning that you define it globally for your whole API if you like:

  {
    "x-mojo-around-action": "MyApp::protect_any_resource",
    "paths": {
      "/pets": {
        "x-mojo-around-action": "MyApp::protect_any_method_under_foo",
        "get": {
          "x-mojo-around-action": "MyApp::protect_just_this_resource"
        }
      }
    }
  }

Custom route

  use Mojolicious::Lite;
  my $route = app->routes->under->to(
    cb => sub {
      my $c = shift;
      return 1 if $c->param('secret');
      return $c->render(json => {error => "Not authenticated"}, status => 401);
    }
  );
  plugin Swagger2 => {
    route => $route,
    url   => "data://api.json",
  };
