Controller is the base class for RESTful API controller classes.

Controller implements the following steps in a RESTful API request handling cycle:

  1. Resolving response format (see yii\filters\ContentNegotiator);
  2. Validating request method (see verbs()).
  3. Authenticating user (see yii\filters\auth\AuthInterface);
  4. Rate limiting (see yii\filters\RateLimiter);
  5. Formatting response data (see serializeData()).

For more details and usage information on Controller, see the guide article on rest controllers.
