  "code": 10000,
  "message": "winning limit 必须是整数。",
  "data": []
}

2. Check the verification code as follows

        $input = $request->json()->all();
        Arr::set($input, 'activity_id', $activityId);
        $factory = Container::getInstance()->make('validator');
        $validator = $factory->make($input, [
            'activity_id' => 'required|uuid|exists:activities,id',
            'prize_id' => 'required|uuid|exists:prizes,id',
            'winning_limit' => 'integer',
            'stock_limit' => 'numeric',
            'winning_probability' => 'numeric|between:0,1',
        ]);

3. Reference URL:https://learnku.com/docs/laravel/5.4/validation/1234#42c1ed. Customize properties in language files. If you want to replace the :attribute part of the validation message with a custom attribute name, you can specify a custom name in the attributes array of the resources/lang/xx/validation.php language file. Edit: resources/lang/en-cn/validation.php

    'attributes'           => [
		'winning_limit'         => '中奖限制',
    ],

4. Laravel’s form validation, the attribute name in the error message: Winning Limit has been replaced with: winning limit. in line with expectations. as shown in Figure 2

}
