Laravel中存储音乐文件及其ID3标签艺术作品的教程

composer require owen-oj/laravel-getid3

php artisan storage:link

use Owenoj\LaravelGetID3\GetID3;
use Illuminate\Support\Facades\Storage;
use Illuminate\Http\UploadedFile; // 引入UploadedFile，以便类型提示更清晰

// 假设 $uploadedFile 是一个 Illuminate\Http\UploadedFile 实例
// 例如：$uploadedFile = $request->file('songs')[$key];

$track = new GetID3($uploadedFile);
$artwork = $track->getArtwork(true); // 获取 Artwork 对象

$thumbnailFileName = null; // 初始化封面图文件名

if ($artwork) {
    $artworkBinary = $artwork->getBinary();     // 获取艺术作品的二进制数据
    $artworkExtension = $artwork->getExtension(); // 获取艺术作品的推荐扩展名 (例如 'jpeg', 'png')

    if ($artworkBinary && $artworkExtension) {
        // 生成一个唯一的封面图文件名
        $thumbnailFileName = 'artwork-' . time() . uniqid() . '.' . $artworkExtension;

        // 使用Laravel的Storage门面存储二进制数据
        // 存储到 public/sthumbs 目录下
        Storage::disk('public')->put('sthumbs/' . $thumbnailFileName, $artworkBinary);
    }
}
