Configuring Static Website Hosting (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 configures static website hosting for a bucket.
If you have any questions during development, post them on the Issues page of GitHub.
Restrictions
- Periods (.) should be avoided in the target bucket name, or there may be certificate verification failures on the client when you use HTTPS for access.
- The request body of the website configuration cannot exceed 10 KB.
- To configure static website hosting for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketWebsite in IAM or PutBucketWebsite in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.
- The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.
Method
obsClient.setBucketWebsite(final SetBucketWebsiteRequest request)
