此兩種方法其實與 user 的部份大致雷同，也是先經過 middleware 檢查後才可執行。

• update

  • 檢查使用者輸入 ( 同樣並非每一項都是必填 )

    $rules = [
        'title' => 'string|min:2|max:500',
        'content' => 'string|min:2|max:1500'
    ];
    
    $validator = Validator::make($request->all(), $rules);
    if($validator->fails()){
        return response(['message' => $validator->errors()]);
    }
    

  • 確認該使用者存在與否，若存在就做修改貼文的動作

    $post = Post::find($id);
    
    if(!is_null($post)){
        $post->update($request->only(['title', 'content']));
        return response(['data' => $post]);
    }
    
    return response(['message' => 'Post not found!']);
    

  完整程式碼
  *PostsController.php

  namespace App\Http\Controllers;
  
  use Illuminate\Http\Request;
  use Illuminate\Support\Facades\Validator;
  use App\Post;
  use App\User;
  
  class PostsController extends Controller
  {
       public function update(Request $request, $id)
      {
          $rules = [
              'title' => 'string|min:2|max:500',
              'content' => 'string|min:2|max:1500'
          ];
  
          $validator = Validator::make($request->all(), $rules);
          if($validator->fails()){
              return response(['message' => $validator->errors()]);
          }
  
          $post = Post::find($id);
  
  
          if(!is_null($post)){
              $post->update($request->only(['title', 'content']));
              return response(['data' => $post]);
          }
  
          return response(['message' => 'Post not found!']);
      }
  }
  

• destroy
  此處也是檢查該貼文存在與否，存在的話就可刪除

  完整程式碼
  *PostsController.php

  namespace App\Http\Controllers;
  
  use Illuminate\Http\Request;
  use Illuminate\Support\Facades\Validator;
  use App\Post;
  use App\User;
  
  class PostsController extends Controller
  {
       public function destroy($id)
      {
          $post = Post::find($id);
          if(!is_null($post)){
              $post->delete();
              return response(['message' => 'Post deleted!!']);
          }
  
          return response(['message' => 'Post not found!']);
      }
  }
  

Postman 測試

為了簡潔重複過的步驟，此處不一一做錯誤的測試

• update

  

• delete

  

然而到此為止依舊有些奇怪，詳情請見下一篇。
