Before You Start

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

• Set AllowedOrigin to *.
• Set AllowedMethod to PUT, GET, POST, DELETE, HEAD.
• Set AllowedHeader to *.
• Set ExposeHeader to:
  • ETag
  • Content-Type
  • Content-Length
  • Cache-Control
  • Content-Disposition
  • Content-Encoding
  • Content-Language
  • Expires
  • x-obs-request-id
  • x-obs-id-2
  • x-reserved-indicator
  • x-obs-api
  • x-obs-version-id
  • x-obs-copy-source-version-id
  • x-obs-storage-class
  • x-obs-delete-marker
  • x-obs-expiration
  • x-obs-website-redirect-location
  • x-obs-restore
  • x-obs-version
  • x-obs-object-type
  • x-obs-next-append-position

Object-Related API functions of ObsClient are case insensitive. For example, ObsClient.putObject and ObsClient.PutObject indicate the same function.
