This extension extends the CController and gives it JSON capabilities for fast development of JSON web services and their documentation.


This has been tested on Yii 1.1.10+


Action Input parameters

You define your input parameters as objects, which are actually the JSON-decoded payload of your caller's request. Decoding and validation takes place transparently, as long as your input object is a subclass of CBJsonModel.

Action Return values

You return your action's response with return instead of render. It's highly suggested that your return objects are subtypes of CBJsonModel or arrays of such objects. Still, this is a suggestion, of course you can return anything that json_encode() accepts, as long as you trust what you're exposing to your caller.

PHPdoc for your json services

The above allow for automatic documentation of your services, e.g. using apigen. The produced documentation can be then published and let your clients/callers know exactly what they should pass as input and what to expect as output.

Consistent error and exception handling

Error handling is done automatically, i.e. whenever an exception or PHP error is thrown, a standard-format JSON is returned which your caller may then parse and handle.


Download and extract the code into /protected/extensions/bogo-yii-json-service/ folder.

Add the following lines in the import array of your /protected/config/main.php to make the extensions classes visible to your code and enable CBHttpRequest functionality in place of Yii's standard CHttpRequest class:

return array(
	// [..]

	// autoloading model and component classes
		// [..]
		// [..]

	// application components
		// [..]

		// Use json-capable http request

		// [..]
	// [..]


Quick sample

Below a sample code which highlights the usage of JSON capabilities. Things you should keep are:

  1. The controller extends the CBJsonController component
  2. The method accepts a ProductQueryJson object instead of looking into $_GET/$_POST
  3. The method returns an array of ProductJson objects instead of calling $this->render()
class ProductController extends CBJsonController
	 * Find products.
	 * @param ProductQueryJson $queryJson Query criteria
	 * @return ProductJson[] Matching products
	public function actionFindProduct(ProductQueryJson $queryJson)
		$foundProducts = Product::model()->scopeApplyQuery($queryJson)->findAll();

		return ProductJson::createFromMany($foundProducts);

Your API's public documentation

Here's the demo controller documentation you get by using this extension in conjunction with proper phpdoc comments and apigen.
