Laravel 5 Flysystem - download file from remote disk
提问by NightMICU
I am storing files for a site on Rackspace using Flysystem. Uploading is no problem, having trouble figuring out how to start a download for a file - this is what I have tried
我正在使用 Flysystem 为 Rackspace 上的站点存储文件。上传没问题，无法弄清楚如何开始下载文件 - 这是我尝试过的
Storage::disk('rackspace');
return response()->download('file-library/' . $file->filename);
The result is that the file could not be found. Is adding Storage::disk()sufficient for making Laravel look in this location rather than locally? What is the best way to accomplish this?
结果是找不到文件。添加是否Storage::disk()足以使 Laravel 看起来在这个位置而不是本地？实现这一目标的最佳方法是什么？

Frank here from Flysystem.
弗兰克来自 Flysystem。
The preferred way to do this would be to use the readStream output in combination with Response::stream.
执行此操作的首选方法是将 readStream 输出与 Response::stream 结合使用。
<?php
$fs = Storage::disk('diskname')->getDriver();
$stream = $fs->readStream($file);
return Response::stream(function() use($stream) {
fpassthru($stream);
}, 200, [
"Content-Type" => $fs->getMimetype($file),
"Content-Length" => $fs->getSize($file),
"Content-disposition" => "attachment; filename=\"" . basename($file) . "\"",
]);
The $fsis the League\Flysystem\Filesysteminstance. I believe there is a method to retrieve this instance in the filesystem class Laravel provides.
该$fs是League\Flysystem\Filesystem实例。我相信有一种方法可以在 Laravel 提供的文件系统类中检索此实例。

添加是否

No, that wouldn't affect response()->download()calls.
不，这不会影响response()->download()通话。
Something like this should work:
这样的事情应该工作：
return response()->download(Storage::disk('rackspace')->get('file-library/' . $file->filename));
