Response header of swift API returned by radosgw does not contain "x-openstack-request-id". But Swift returns it.
Found the bug when verified Swift API with Ceph radosgw. According to OpenStack Swift API document (https://docs.openstack.org/developer/swift/api/object_api_v1_overview.html?highlight=openstack), the response header of swift API should contain "x-openstack-request-id", its value is same as X-Trans-Id. For example:
curl -i -X PUT -H "Content-Type: application/json" -H "Accept: application/json" -H "X-Auth-Token: xxxxxxxxxxx" http://10.169.42.41:7480/swift/v1/AUTH_d6b422cc66fd4cd4ab9e1f2424b3cb36/Container1/TestObject-1 -d "testtesttes"
HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
