添加验证消息

$this->validate($request, [
            'firstName'=>'required|string|between:3,15',
            'email'=>'required|email',
            'password'=>'required|regex:/^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{6,}$/',
            'mobile'=>'required|digits:10',
            ],[
        'mobile.required' => 'Please enter mobile number',
        'mobile.digits' => 'Please enter valid mobile number',
    ]);
