最後一篇就來點輕鬆的吧？？

api routes

category 的 routes 就只有簡單的兩個

*api.php

// 顯示所有種類
Route::get('categories', 'CategoriesController@index');

// 顯示該種類所含的所有貼文
Route::get('categories/{id}/posts', 'CategoriesController@categoryPosts');

Controller

• 建立 Controller

  $ php artisan make:controller CategoriesController
  

• index method

  *CategoriesController.php

  public function index()
  {
      return response(['data' => Category::get()]);
  }
  

• categoryPosts method

  *CategoriesController.php

  public function categoryPosts($id)
  {
      $category = Category::find($id);
      if(!is_null($category)){
          return response(['data' => $category->posts]);
      }
      return respoonse(['message' => 'Category not found!']);
  }
  

完整程式碼：

*CategoriesController.php

<?php

namespace App\Http\Controllers;

use App\Category;
use Illuminate\Http\Request;

class CategoriesController extends Controller
{
    public function index(){
        return response(['data' => Category::get()]);
    }

    public function categoryPosts($id){
        $category = Category::find($id);
        if(!is_null($category)){
            return response(['data' => $category->posts]);
        }
        return respoonse(['message' => 'Category not found!']);
    }
}

Postman 實測

• index

• categoryPosts
