کار با postman

prefix رو اشتباه نوشتید.

سلام 

خط اول ارور گفته شده که این روتی که دارید کال میکنید وجود نداره

سلام

خب الان بر اساس اون روت ام که در api.php  تعریف کردم

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;


Route::group(['perfix'=>'v1'],function (){

    Route::resource('Article','ArticleController');
});

میشه

http://127.0.0.1:8000/v1/Article

خب حالا باز هم ارور میده
