Object Storage Service:Download files (Browser.js SDK)

Last Updated:Nov 29, 2025

The OSS Browser.js Software Development Kit (SDK) provides several methods to download files. Choose a method based on your scenario:

  • To download or preview a file using a URL, use the signatureUrl method in a browser to generate a file URL for preview or download. For more information, see Preview or download a file (Browser.js SDK).

  • To download only part of a file's data, use range download. For more information, see Range download (Browser.js SDK).

  • To restrict a download based on multiple conditions, use conditional download. For example, you can download only files modified before a specified time or files that match a specified ETag. For more information, see Conditional download (Browser.js SDK).
