Swagger Authenticate the API in Laravel

In previous article we Create Swagger Post Method in Laravel and Create Swagger GET Method in Laravel. Now we will do Swagger Authenticate the API in Laravel.

Open config/l5-swagger.php file and add securityDefinitions and securitySchemes. Check Create Swagger Configuration in Laravel.

'securityDefinitions' => [
            'securitySchemes' => [
                /*
                 * Examples of Security schemes
                */
                'Authentication_Token' => [ // Unique name of security
                    'type' => 'apiKey', // The type of the security scheme. Valid values are "basic", "apiKey" or "oauth2".
                    'description' => 'An authorization header. Example: Token',
                    'name' => 'Authorization', // The name of the header or query parameter to be used.
                    'in' => 'header', // The location of the API key. Valid values are "query" or "header".
                ],
            ]
        ]

Now, add security=} comment in functions. If required We can also access the token in header Authorization.

/**
     * @OA\Get(
     *      path="/get-user/{id}",
     *      operationId="getUser",
     *      tags={"User"},
     *      summary="Get User",
     *      description="Get User",
     *      security=},
     *      @OA\Parameter(
     *      name="id",
     *      in="path",
     *      required=true,
     *      description= "user id",
     *      example="10",
     *      @OA\Schema(
     *           type="integer"
     *      )
     *      ),
     *       @OA\Response(
     *      response=200,
     *      description="Success response",
     *      @OA\JsonContent(
     *      @OA\Property(property="status", type="number", example="200"),
     *      @OA\Property(property="user", type="string", example="{'full_name':'Chetan','email_id':'chetan1234@gmail.com','created_at':'2022-05-27T07:16:57.000000Z','updated_at':'2022-05-27T07:16:57.000000Z'}"),
     *        )
     *     ),
     *        @OA\Response(
     *      response=400,
     *      description="Bad Request",
     *      @OA\JsonContent(
     *      @OA\Property(property="status", type="number", example="400"),
     *      @OA\Property(property="message", type="string", example="Error in processing request")
     *        )
     *     )
     * )
     *      
     * )
     */

    public function getUser($id)
    {
    	try {
	    	$user = User::where('id', $id)->get();

	    	if($user){
	    		return response()->json(['status' => 200, 'user' => $user], 200);
	    	}
    	}catch (\Exception $e) {
            return response()->json(['status' => 400, 'message' => 'Error in processing request'], 400);
        }
    }

In routes/api.php add middleware auth:api.

Route::group(['middleware' => ['auth:api']], function () {

});

Now, run php artisan l5-swagger:generate and check api at https://mywebsite.com/api/documentation.
