文件 URL

 

使用 local 或 s3 驅動時，可以使用 url 方法獲取給定文件的 URI。如果你使用的是 local 驅動，通常會在給定路徑前加上 /storage，並返回該文件的相對 URL；如果使用的是 s3 或 rackspace 驅動，則會返回完整的遠程 URL：

use Illuminate\Support\Facades\Storage; 
$url = Storage::url('file1.jpg');

 

注：記住，如果你在使用 local 驅動，所有需要公開訪問的文件都應該存放在 storage/app/public 目錄下，此外，你還需要創建一個指向 storage/app/public 目錄的軟鏈接 public/storage。
