Laravel 中上传音乐文件并存储其封面图（Artwork）的教程

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Storage;
use getID3; // 确保已正确引入 getID3 类
use App\Models\MusicUpload; // 假设您的模型名为 MusicUpload

class MusicController extends Controller
{
    public function upload(Request $request)
    {
        // 1. 验证请求
        $request->validate([
            'songs.*' => 'required|file|mimes:mp3,wav,ogg|max:20480', // 示例：最大20MB
        ]);

        if ($request->hasFile('songs')) {
            foreach ($request->file('songs') as $file) { // $file 是音乐文件的 UploadedFile 实例
                // 2. 初始化 getID3 并提取元数据
                $track = new getID3($file->getPathname()); // getID3 需要文件路径
                $tifo = $track->extractInfo();

                // 检查是否成功解析
                if (!empty($tifo['error'])) {
                    // 处理解析错误，例如记录日志或跳过此文件
                    continue;
                }

                $artistName = $track->getArtist() ?? '未知艺术家';
                $songName = $track->getTitle() ?? '未知歌曲名';
                $albumName = $track->getAlbum() ?? '未知专辑';
                $extension = $track->getFileFormat() ?? $file->getClientOriginalExtension();

                // 3. 存储音乐文件
                $musicFileName = time() . uniqid() . '.' . $extension;
                // storeAs 方法会返回文件的相对路径，例如 'public/songs/12345.mp3'
                $musicFilePath = $file->storeAs('public/songs', $musicFileName);

                // 4. 提取并存储封面图
                $thumbnail = $track->getArtwork(true); // $thumbnail 是封面图的 UploadedFile 实例
                $thumbnailFilePath = null; // 默认封面图路径为 null

                if ($thumbnail instanceof \Symfony\Component\HttpFoundation\File\UploadedFile) {
                    // 确保封面图存在且是 UploadedFile 实例
                    $thumbnailExtension = $thumbnail->getClientOriginalExtension() ?? 'jpg'; // 默认扩展名
                    $thumbnailFileName = 'artwork-' . time() . '-' . uniqid() . '.' . $thumbnailExtension;
                    // 存储封面图，同样返回相对路径
                    $thumbnailFilePath = $thumbnail->storeAs('public/sthumbs', $thumbnailFileName);
                } else {
                    // 如果没有提取到封面图，可以设置一个默认封面图路径或留空
                    // $thumbnailFilePath = 'public/sthumbs/default.jpg';
                }

                // 5. 保存文件信息到数据库
                $musicUpload = new MusicUpload();
                $musicUpload->user_id = Auth::id(); // 使用 Auth::id() 获取当前用户ID
                $musicUpload->filename = $songName;
                $musicUpload->extension = $extension;
                $musicUpload->artistname = $artistName;
                $musicUpload->albumname = $albumName;
                $musicUpload->location = $musicFilePath; // 存储音乐文件相对路径
                $musicUpload->thumbnail = $thumbnailFilePath; // 存储封面图相对路径
                $musicUpload->save();
            }
        }

        return redirect()->back()->with('success', '音乐文件上传成功！');
    }
}
