* 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 [[ContentNegotiator]]);
|
|
* 2. Validating request method (see [[verbs()]]).
|
|
* 3. Authenticating user (see [[\yii\filters\auth\AuthInterface]]);
|
|
* 4. Rate limiting (see [[RateLimiter]]);
|
|
* 5. Formatting response data (see [[serializeData()]]).
|
|
*
|
|
* For more details and usage information on Controller, see the [guide article on rest controllers](guide:rest-controllers).
