Obtaining Static Website Hosting Configurations (SDK for Java)

Function

You can host static website resources such as HTML web pages, flash files, or audio and video files in an OBS bucket, so that you can provide these hosted resources using the bucket's website endpoint to end users. Typical use cases include:

  • Redirecting all requests to another website
  • Redirecting specific requests to another website

This API returns the static website hosting configurations of the bucket.

If you have any questions during development, post them on the Issues page of GitHub.
