Regarding the generation of URLs when using APIs
The APIs require URLs of the object-store type, which can be generated by the identity service on the Service catalog.
The endpoint URL is returned in the following format by the identity service.
https://hostName/v1/AUTH_{project_id}
In the descriptions that follow, "AUTH_{project_id}" is referred to as "{account}".
In addition, in the object storage API "Project" is indicated as "Account".
