javascript - 无法使用 Node.js SDK 下载文件夹内的 blob

Question

我正在尝试下载 Azure 中 Blob 容器中的一些 Blob。

当文件位于根容器上时我成功，但当文件位于文件夹内时则失败。

const folder = 'AZURE_FOLDER';

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

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

运行此代码，下载的文件是“icon.ico”，但我收到此错误的所有其他文件:

error : { Error: ENOENT: no such file or directory, open 'AZURE_FOLDER/images/cover.jpg'

error : { Error: ENOENT: no such file or directory, open 'AZURE_FOLDER/images/htmlstructure.png'

我的 listBlob 响应:

Answer 1

AZURE_FOLDER/images 目录是否存在？如果没有，您需要事先使用 fs 模块创建它。
