Laravel 6 pathinfo() 期望参数 1 为字符串，给定的对象

Question

这是我收到错误的地方：

$data = Excel::import($path, function($reader) {})->get();

我将 load() 更改为 import()。我想运行这段代码在Laravel 6，但是MaatWebsiteExcel 3版本不支持load()。我一直在寻找解决方案，但我找不到任何....

这是我的控制器：

namespace App\Http\Controllers;

use App\Contact;
use App\CsvData;
use App\Http\Requests\CsvImportRequest;
use Illuminate\Http\Request;
use Maatwebsite\Excel\Facades\Excel;
use Session;
use DB;

class ImportController extends Controller
{

    public function getImport()
    {
        return view('import');
    }

     function parseImport(CsvImportRequest $request)
    {

        $path = $request->file('csv_file')->getRealPath();

        if ($request->has('header')) {
            $data = Excel::import($path, function($reader) {})->get();
        } else {
            $data = array_map('str_getcsv', file($path));
        }

        if (count($data) > 0) {
            if ($request->has('header')) {
                $csv_header_fields = [];
                foreach ($data[0] as $key => $value) {
                    $csv_header_fields[] = $key;
                }
            }
            $csv_data = array_slice($data, 0, 2);

            $credentials = $request->file('csv_file')->getClientOriginalName();
            $filename = CsvData::all('csv_filename');


            if(CsvData::where('csv_filename', '=' ,$credentials)->exists()){

            return redirect()->back()->with('alert', 'This specific file has already been imported!');

            }
            else{
             $csv_data_file = CsvData::create([
                'csv_filename' => $request->file('csv_file')->getClientOriginalName(),
                'csv_header' => $request->has('header'),
                'csv_data' => json_encode($data)
                ]);

            }

        }
         else {
            return redirect()->back();
        }

        return view('import_fields', compact( 'csv_header_fields', 'csv_data', 'csv_data_file'));

    }

    public function processImport(Request $request)
    {
        $data = CsvData::find($request->csv_data_file_id);
        $csv_data = json_decode($data->csv_data, true);

        if(CsvData::where('csv_data', '=' ,$csv_data)->exists()){
        return redirect()->back()->with('alert', 'This file has already been imported!');
    }
        else{

            foreach ($csv_data as $row) {
            $contact = new Contact();

            foreach (config('app.db_fields') as $index => $field) {

import()方法的第一个参数不再是Laravel 3.1中的文件路径，而是Import文件的class名称创造。您需要按照以下步骤使用 import 方法

第 1 步： 使用以下命令创建导入文件。

php artisan make:import CsvImport

第 2 步： 在 CsvImport 中进行如下更改：

namespace App\Imports;
use Illuminate\Support\Collection;
use Maatwebsite\Excel\Concerns\ToCollection;

class CsvImport implements ToCollection
{
    public function collection(Collection $rows)
    {
        return $rows; //add this line
    }
}

第 3 步： 在 Controller 中进行如下更改：

 $path = $request->file('csv_file')->getRealPath();
 $rows = Excel::import(new CsvImport, $path);
