php - 拉维尔 : How do I save a JSON object to MYSQL database?

Question

我想使用 Laravel API 将数据从前端发布到后端的 MYSQL 数据库。我尝试了以下代码，但它在尝试发布时输出了 500: Internal Server Error。

public function postOrder(Request $request)
{
    /*
     $request is a JSON Object which looks like
     {"order":{"table_id":2,"food_id":4,"status":1}}
    */

    $order = new Order();
    $order->table_id  = $request->order->table_id;
    $order->food_id   = $request->food_id;
    $order->user_id   = $request->user_id;
    $order->status    = $request->status;
    $order->save();

    return response()->json(['message' => 'Order Added'], 201);
}

我应该json_decode($request)吗？怎么办？

当我error_log($request)时，这是我得到的:

{"order":{"table_id":2,"food_id":4,"time":"333","status":1}}

Answer 1

你需要使用json_decode()来得到一个关联数组:

$json = '{"order":{"table_id":2,"food_id":4,"time":"333","status":1}}';

$array = json_decode($json, true);

var_dump($array['order']); //Here you can see that it is an associative array with the needed values now

然后您可以基于它创建一个模型。

$order = Order::create($array['order']);
