無法使用Node.js SDK下載文件夾內的Blob

Question

我正在嘗試在azure的blob容器中下載一些blob。

當文件放在根容器中時，我成功了，但是當它在文件夾中時，我沒有成功。

const folder = 'AZURE_FOLDER';

const filesToDownload =  [ 'icon.ico', 'images/cover.jpg', 'images/htmlstructure.png' ]

filesToDownload.forEach(blob => {
      service.download(containerName, blob, `${folder}/${blob}`)
});

運行此代碼，下載的文件為“ icon.ico”，但所有其他我收到此錯誤：

錯誤：{錯誤：ENOENT：沒有這樣的文件或目錄，請打開'AZURE_FOLDER / images / cover.jpg'

錯誤：{錯誤：ENOENT：沒有這樣的文件或目錄，請打開'AZURE_FOLDER / images / htmlstructure.png'

Answer 1

AZURE_FOLDER/images目錄是否存在？ 如果不是，則需要預先使用fs模塊創建它。
