Laravel 5:如何处理json请求中的嵌套对象

I just started working on Laravel 5. I am sending json request to my controller. It works fine for simple json. Now I have a scenario where json will be something like this

我刚开始研究Laravel 5。我正在向我的控制器发送json请求。它对简单的json很有效。现在我有一个场景，json将是这样的。

{
"orders":[
        {
          "user_id":"1",
          "product_id":"10"
        },
        {
            "user_id":"1",
          "product_id":"15"
        },
    ]
}

It can get more complex with nested objects. Inside my controller what I have been doing is simply like

使用嵌套对象会变得更复杂。在我的控制器里，我一直在做的事情很简单

<?php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class ordersController extends Controller 
{
    public function __construct( Request $request)
    {
      //$this->middleware('products.prodcutsList');
    }

    public function makeOrder(Request $request)
    {
        $order_data= $request->only('orders');
        print_r($order_data);
    }
}

response I get is looks like this

我得到的响应是这样的

Array
(
    [orders] => 
)

Please guide how can I get this in an array.

请指导如何在数组中获取这个。

I'm not sure that will resolve you problem but your json is not correct you have to remove extra comma in the end :

我不确定这是否能解决你的问题，但你的json是不正确的，最后你必须删除额外的逗号:

{
"orders":[
        {
          "user_id":"1",
          "product_id":"10"
        },
        {
            "user_id":"1",
          "product_id":"15"
        }, //remove this comma 
_________^ 
    ]
}

Note : You can use the following pretty website to validate you JSON jsonformatter.

You send your data as form data. Use the php input wrapper:

您将数据作为表单数据发送。使用php输入包装器:

$input = file_get_contents('php://input'); // json
print_r(json_decode($input)); // decode to php array
