Class JsonView

A view class that is used for JSON responses.

It allows you to omit templates if you just need to emit JSON string as response.

In your controller, you could do the following:

$this->set(['posts' => $posts]);
$this->set('_serialize', true);

When the view is rendered, the $posts view variable will be serialized into JSON.

You can also set multiple view variables for serialization. This will create a top level object containing all the named view variables:

$this->set(compact('posts', 'users', 'stuff'));
$this->set('_serialize', true);

The above would generate a JSON object that looks like:

{"posts": [...], "users": [...]}

You can also set '_serialize' to a string or array to serialize only the specified view variables.

If you don't use the _serialize, you will need a view template. You can use extended views to provide layout-like functionality.

You can also enable JSONP support by setting parameter _jsonp to true or a string to specify custom query string parameter name which will contain the callback function name.

Methods used from Cake\Routing\RequestActionTrait

requestAction() public deprecated ¶

requestAction( string|array $url , array $extra = [] )

Calls a controller's method from any location. Can be used to connect controllers together or tie plugins into a main application. requestAction can be used to return rendered views or fetch the return value from controller actions.

Under the hood this method uses Router::reverse() to convert the $url parameter into a string URL. You should use URL formats that are compatible with Router::reverse()

Examples

A basic example getting the return value of the controller action:

$variables = $this->requestAction('/articles/popular');

A basic example of request action to fetch a rendered page without the layout.

$viewHtml = $this->requestAction('/articles/popular', ['return']);

You can also pass the URL as an array:

$vars = $this->requestAction(['controller' => 'articles', 'action' => 'popular']);

Passing other request data

You can pass POST, GET, COOKIE and other data into the request using the appropriate keys. Cookies can be passed using the cookies key. Get parameters can be set with query and post data can be sent using the post key.

$vars = $this->requestAction('/articles/popular', [
  'query' => ['page' => 1],
  'cookies' => ['remember_me' => 1],
]);

Sending environment or header values

By default actions dispatched with this method will use the global $_SERVER and $_ENV values. If you want to override those values for a request action, you can specify the values:

$vars = $this->requestAction('/articles/popular', [
  'environment' => ['CONTENT_TYPE' => 'application/json']
]);

Transmitting the session

By default actions dispatched with this method will use the standard session object. If you want a particular session instance to be used, you need to specify it.

$vars = $this->requestAction('/articles/popular', [
  'session' => new Session($someSessionConfig)
]);

Deprecated

3.3.0 You should refactor your code to use View Cells instead of this method.

Parameters

string|array $url: String or array-based url. Unlike other url arrays in CakePHP, this url will not automatically handle passed arguments in the $url parameter.
