Lumen：通過json主體更新記錄

Question

我有一個Laravel Lumen API。我看到更新功能的問題。

在我的控制器，用於更新項目的代碼是：

public function update(Request $request, $id) 
    { 

     $this->validate($request, [ 
      'name' => 'required', 
      'description' => 'required', 
      'completed' => 'required', 
     ]); 

     $todo = Todo::find($id); 
     $todo->name = $request->name; 
     $todo->description = $request->description; 
     $todo->completed = $request->completed; 
     $todo->save(); 
     return response()->json(['status' => 'success']); 
    } 

我可以使用更新的待辦事項：

http://lumen-todo.app/api/51?name=test&description=test&completed=1 

但希望我能在一個JSON體發送參數，像這樣

PUT http://lumen-todo.app/api 
{ 
    "id": 1 
    "name": "Test", 
    "description": "Test", 
    "completed": 1, 
} 

對於添加項目，它通過json的身體工作，所以不明白爲什麼它d oes不適用於更新。對於信息， '添加項目' 控制代碼是在這裏：

public function store(Request $request) 
{ 

    $this->validate($request, [ 
     'name' => 'required', 
     'description' => 'required', 
     'completed' => 'required' 
    ]); 

    $todo = new Todo(); 
    $todo->name = $request->name; 
    $todo->description = $request->description; 
    $todo->completed = $request->completed; 
    $todo->save(); 
    return response()->json(['status' => 'success']); 

} 

Answer 1

而不是這樣做：

$todo = new Todo(); 
$todo->name = $request->name; 
$todo->description = $request->description; 
$todo->completed = $request->completed; 
$todo->save(); 

做的，這樣的：

use App\Todo; 

protected $model; 

public function __construct(Todo $model) { 
    $this->model = $model; 
} 

$resource = $this->model->find($id); 
$resource->fill($request); 
$resource->save(); 

此外，您還可以做json_decode()功能把你的json params改成數組，並用它來驗證和保存數據。

Answer 2

如果你想從請求負載JSON數據，驗證和存儲，使用

public function store(Request $request) 
{ 
    $data = $request->json()->all(); 

    $this->validate($data, [ 
     'name' => 'required', 
     'description' => 'required', 
     'completed' => 'required' 
    ]); 

    $resource = $this->model->find($id); 

    $resource->fill($request); 
    $resource->save(); 

    return response()->json(['status' => 'success']);  
}
