問題描述

如何通過 Storage Facade（在 Laravel 5 中）獲取下載文件的進度條？ (How to get a progress bar for downloading a file via Storage Facade (in Laravel 5)?)

您好，這是我用於使用 Laravel5 和 Storage Facade 為虛擬磁盤下載文件的代碼（非常簡單）：

//implemented as a Artisan Console command
$contents = Storage::disk('remoteDisk')‑>get($filePath);
Storage::disk('csv')‑>put($filePathTarget, $contents); 

我希望在輸出中看到一個進度條，如文檔建議：

$bar = $this‑>output‑>createProgressBar($count);
//do something
$bar‑>advance();
//i'm done
$bar‑>finish();

既然Storage方法get()不是循環，那如何“推進”進度條呢？

初始化可以是：

  $size_remote = Storage::disk('remoteDisk')‑>size($filePath);
  $size = Storage::disk('csv')‑>size($filePath);

但是如何/在哪裡獲取臨時文件文件大小以在下載期間推進進度條？

參考解法

方法 1:

It's doable, but you are going to need JavaScript.

Also it's been answered already on StackOverflow here.
