将多个记录从json文件导入到Laravel项目内的DB中

Question

解决！将在今晚发布工作答案。可能对别人有帮助。

我正在尝试运行几个月前制作的脚本。该脚本设置为与填充.json文件的目录（每个包含200个项目的45个文件）一起使用，并运行这些文件以获取数据，然后将其与查询一起存储在数据库中。

问题是我不能在我的laravel项目中使用$ conn所以我不知道如何我现在可以连接到数据库并存储我的所有数据。我可以读取json没问题，我在laravel项目中有一个模型用于相应的表，所有字段都设置为可填充。

这是我的代码：

 <?php
namespace App\Http\Controllers;

use DB;
use App\Http\Controllers\Controller;

class JsonController extends Controller
{
    public function importJson() {
$path = realpath('AllSetFiles/');

        foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename)
        {
            if ($filename->isDir()) continue;

            // Include the JSON and put it inside $data.
            $jsondata = file_get_contents($filename);
            $data = json_decode($jsondata, true);

            // Echo the variables to the screen or put them in the database. (y shows to screen)
            $echo = "n";

            // foreach card in cards in the JSON file put all values in their named variables.
            foreach($data['cards'] as $cards => $values) {

                if(isset($values['multiverseid'])) {
                    $multiverseid = $values['multiverseid'];
                } else {
                    $multiverseid = "";
                }

                if (isset($values['manaCost'])) {
                    $manaCost_array = array();
                    $manaCost_array = array($values['manaCost']);
                    $manaCost = implode (", ", $manaCost_array);

                }

            } // end foreach recursiveIterator
} // end of function importJson
} // end of class

?>

在我的routes.php中：

// JSON
Route::get('importjson', 'JsonController@importJson');

转到myapp.com/importjson会出现以下错误：

Class 'App\Http\Controllers\RecursiveIteratorIterator' not found
