Before You Start

Due to browser limitations, configure CORS for buckets before calling bucket-related APIs as follows:

• Set AllowedOrigin to *.
• Set AllowedMethod to PUT, GET, POST, DELETE, and HEAD.
• Set AllowedHeader to *.
• Set ExposeHeader to:
  • ETag
  • x-obs-request-id
  • x-obs-id-2
  • x-reserved-indicator
  • x-obs-api
  • x-obs-bucket-location
  • x-obs-version
  • x-obs-storage-class
  • x-default-storage-class

Bucket-related API functions of ObsClient are case insensitive. For example, ObsClient.getBucketLocation and ObsClient.GetBucketLocation indicate the same function.
