下列命令會擷取名
my-bucket
為的值區的跨來源資源共用設定:aws s3api get-bucket-cors --bucket
my-bucket
輸出:
{ "CORSRules": [ { "AllowedHeaders": [ "*" ], "ExposeHeaders": [ "x-amz-server-side-encryption" ], "AllowedMethods": [ "PUT", "POST", "DELETE" ], "MaxAgeSeconds": 3000, "AllowedOrigins": [ "http://www.example.com" ] }, { "AllowedHeaders": [ "Authorization" ], "MaxAgeSeconds": 3000, "AllowedMethods": [ "GET" ], "AllowedOrigins": [ "*" ] } ] }
