如何将大型文件从S3流式传输到laravel视图

Question

我有这个主要工作,但很难完成它.

现在我有一条简单的路线:

Route::get('file/{id}/', 'FileController@fileStream')->name('file');

此路由连接到FileController中的操作:

public function fileStream($id){

    $audio = \App\Audio::where('id', $id)->first();

    $client = S3Client::factory([
        'credentials' => [
            'key'    => env('AWS_ACCESS_KEY_ID'),
            'secret' => env('AWS_SECRET_ACCESS_KEY'),
        ],
        'region' => env('S3REGION'),
        'version' => 'latest',
    ]);


    // Register the stream wrapper from an S3Client object
    $client->registerStreamWrapper();

    if ($stream = fopen('s3://[bucket_name]/'. $audio->audio_url, 'r')) {
        while (!feof($stream)) {
            echo fread($stream, 1024);
        }
        fclose($stream);
    }    
}

这适用于浏览器:如果我转到url:/ file/1它会查找正确的文件,并在一个干净的浏览器窗口中得到:

然后在我看来,我试图输出音频,如:

   <audio>
      <source src="{{ url('file', ['id' => $section->id]) }}" type="{{ $section->audio_mime_type}}"></audio>
   </audio>

但没有玩家输出到屏幕.

TIA

您应该使用 Laravel Streamed 响应

return response()->streamDownload(function () use ($audio) {
    if ($stream = fopen('s3://[bucket_name]/'. $audio->audio_url, 'r')) {
        while (!feof($stream)) {
            echo fread($stream, 1024);
            flush();
        }
        fclose($stream);
    }    
}, 'file-name.ext');
