```

```php
$api->version('v1', function ($api) {
    $api->get('user', ['middleware' => 'api.auth', function () {
        // This route requires authentication.

    $api->get('user', function () {
        $user = app('Dingo\Api\Auth\Auth')->user();

        return $user;
    });
});
```

use Dingo\Api\Routing\Helpers;
use Illuminate\Routing\Controller;

class UserController extends Controller
{
    use Helpers;

    public function __construct()
    {
        $this->middleware('api.auth');
    }

Manually set the HTTP status code for a response.

```php
return $this->response->item($user, new UserTransformer)->setStatusCode(200);
```

--------------------------------

### Define Specific Route Scopes

Source: https://github.com/dingo/api/wiki/OAuth-2.0

Apply scopes to an individual route definition within an API version group.

```php
$api->version('v1', ['middleware' => 'api.auth'], function ($api) {
    $api->get('user', ['scopes' => 'read_user_data', function () {
        // Only access tokens with the "read_user_data" scope will be given access.
    }]);
});

    ]
];
```

--------------------------------

### Define Route Group Scopes

Source: https://github.com/dingo/api/wiki/OAuth-2.0

```php
$api->version('v1', ['middleware' => 'api.auth', 'scopes' => ['read_user_data', 'write_user_data']], function ($api) {
    // Only access tokens with the "read_user_data" scope will be given access.
});
```

--------------------------------

### Define API Transactions with PHP Annotations

Source: https://github.com/dingo/api/wiki/API-Blueprint-Documentation

Use the @Transaction annotation to group multiple request and response scenarios for a single endpoint.

```php
/**
 * Register user
 *
 * Register a new user with a `username` and `password`.
 *
 * @Post("/")
 * @Versions({"v1"})
 * @Transaction({
 *      @Request({"username": "foo", "password": "bar"}),
 *      @Response(200, body={"id": 10, "username": "foo"}),

 * })
 */
public function store()
{

}
```

--------------------------------

### Conditionally modify response based on authentication status

Source: https://github.com/dingo/api/wiki/Authentication

Use the Dingo Auth service to check for an authenticated user inside an unprotected route. This allows hiding sensitive fields like email addresses from unauthenticated requests.

```php
$api->version('v1', function ($api) {
    $api->get('users/{id}', function ($id) {
        $user = User::findOrFail($id);

        // Attempt to authenticate the request. If the request is not authenticated
        // then we'll hide the e-mail from the response. Only authenticated
        // requests can see other users e-mails.
        if (! app('Dingo\Api\Auth\Auth')->user()) {
            $hidden = $user->getHidden();

            $user->setHidden(array_merge($hidden, ['email']));
        }

        return $user;
    });
});
```

--------------------------------

### Send JSON Data

Source: https://github.com/dingo/api/wiki/Internal-Requests

Send JSON payloads by using the json() method; arrays are automatically encoded.

```php
$data = ['name' => 'bill', 'password' => 12345];

$dispatcher->json($data)->post('users');
```

=== COMPLETE CONTENT === This response contains all available snippets from this library. No additional content exists. Do not make further requests.
