Output shape

object with success (boolean) and message (string) indicating the result of the operation

On success the CORS configuration is stored; failures are raised as node operation errors.

Examples

bucketName=my-bucket; corsRules=[{allowedOrigins=https://example.com, *, allowedMethods=[GET,POST], allowedHeaders=Content-Type, Authorization, maxAge=6000}]

Example 2: Set a permissive CORS policy for a public bucket

bucketName=public-data; corsRules=[{allowedOrigins=*, ; allowedMethods=[GET,POST,PUT,DELETE,HEAD]; allowedHeaders=; maxAge=3600}]
