如何在laravel中使用awssdk嵌入quicksight仪表板?

我有一个 laravel 5.3 我需要展示一个项目 aws quicksight 图,我的问题是我不知道如何从AWS SDK获取图嵌入url。

我在一个 lambda-node 项目成功了,但在laravel,它又回来了 {}

这是我的代码,它没有显示任何错误 status 200

<?php

namespace App\Http\Controllers;

use Aws\QuickSight\QuickSightClient; 
use Illuminate\Http\Request;
use App\Models\QuicksightDashboard;

class DashboardController extends Controller
{
    //
    public function getDashboard($id) {
        $dashboards = QuicksightDashboard::find($id);
        $quick = new QuickSightClient([
            'version' => 'latest',
            'region'  => 'us-east-1',
            'credentials' => [
              'key'    => '...',
              'secret' => '...',
            ]
        ]);

        $result = $quick->GetDashboardEmbedUrl([
            'AwsAccountId' => '...',
            'DashboardId' => '...',
            'IdentityType' => 'IAM',
            'ResetDisabled' => true,
            'SessionLifetimeInMinutes' => 600,
            'UndoRedoDisabled' => false
        ]);
        return response()->json([
            'code' => 200,
            'message' => 'Operation successfull',
            'dashboard' => $result,
        ]);
    }
}

正如我之前提到的,我正在传递正确的证书和权利 accountId 和 dashboardId 我还缺少什么?
