Laravel音乐文件上传与封面图（Artwork）提取及存储教程

composer require owen-oj/laravel-getid3

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Storage;
use Owenoj\LaravelGetID3\GetID3;
use App\Models\MusicUpload; // 假设您有MusicUpload模型

class MusicUploadController extends Controller
{
    public function upload(Request $request)
    {
        // 1. 验证请求
        $request->validate([
            'songs.*' => 'required|file|mimes:mp3,wav,ogg,flac|max:50000', // 示例验证规则
        ]);

        if ($request->hasFile('songs')) {
            foreach ($request->file('songs') as $key => $file) {
                // 2. 使用getID3包解析音乐文件
                $track = new GetID3($file);
                $tifo = $track->extractInfo(); // 提取所有信息，可选
                $artistName = $track->getArtist();
                $songName = $track->getTitle();
                $albumName = $track->getAlbum();
                $extension = $track->getFileFormat();

                // 3. 存储音乐文件
                // 生成唯一文件名，确保不冲突
                $musicFilename = time() . uniqid() . '.' . $extension;
                // 将音乐文件存储到 'public/songs' 目录下
                // Laravel的storeAs方法会自动处理文件移动和存储
                $file->storeAs('public/songs', $musicFilename);

                // 4. 提取并存储封面图（Artwork）
                $thumbnail = $track->getArtwork(true); // 获取封面图的UploadedFile实例

                // 检查是否成功提取到封面图
                if ($thumbnail && $thumbnail->isValid()) {
                    // 生成封面图的唯一文件名
                    $thumbnailExtension = $thumbnail->getClientOriginalExtension() ?: 'jpg'; // 默认jpg
                    $thumbnailFilename = 'artwork-' . time() . uniqid() . '.' . $thumbnailExtension;

                    // 将封面图存储到 'public/sthumbs' 目录下
                    // 使用Storage Facade的putFileAs方法，它接受UploadedFile实例
                    Storage::disk('public')->putFileAs('sthumbs', $thumbnail, $thumbnailFilename);
                } else {
                    $thumbnailFilename = null; // 如果没有封面图，则存储为null
                }

                // 5. 将文件信息保存到数据库
                $music_upload_file = new MusicUpload();
                $music_upload_file->user_id = Auth::user()->id;
                $music_upload_file->filename = $songName;
                $music_upload_file->extension = $extension;
                $music_upload_file->artistname = $artistName;
                $music_upload_file->albumname = $albumName;
                $music_upload_file->location = 'songs/' . $musicFilename; // 存储相对路径
                $music_upload_file->thumbnail = $thumbnailFilename ? 'sthumbs/' . $thumbnailFilename : null; // 存储相对路径
                $music_upload_file->save();
