如何使用laravel和vuejs下载文件

Route::get('/download/{filename}', 'DownloadController@download')->name('download');

php artisan make:controller DownloadController

<?php

namespace App\Http\Controllers;

use Illuminate\Support\Facades\Storage;

class DownloadController extends Controller
{
    public function download($filename)
    {
        $path = storage_path('app/public/' . $filename);
        
        if (file_exists($path)) {
            return response()->download($path);
        } else {
            abort(404, 'File not found.');
        }
    }
}

methods: {
    downloadFile(filename) {
        window.location.href = '/download/' + filename;
    }
}

<button @click="downloadFile('example.pdf')">下载文件</button>
