如何在laravel中将数据库结果导出为excel文件？

composer require maatwebsite/excel

Maatwebsite\Excel\ExcelServiceProvider::class,

'Excel' => Maatwebsite\Excel\Facades\Excel::class,

php artisan vendor:publish --provider="Maatwebsite\Excel\ExcelServiceProvider"

php artisan make:export UsersExport --model=User

<?php

namespace App\Exports;

use App\User;
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\WithHeadings;

class UsersExport implements FromCollection, WithHeadings
{
    public function collection()
    {
        return User::all();
    }

    public function headings(): array
    {
        return [
            'ID',
            'Name',
            'Email',
            'Created At',
            'Updated At',
        ];
    }
}

use App\Exports\UsersExport;
use Maatwebsite\Excel\Facades\Excel;

class UserController extends Controller
{
    public function export()
    {
        return Excel::download(new UsersExport, 'users.xlsx');
    }
}

Route::get('users/export', 'UserController@export');
