Using SwiftClient
Common usecase
Get token
swift auth
export OS_STORAGE_URL=https://hcm.vstorage.vnglab.com/v1/AUTH_afa7086fbef044938dbb7d8d328d452a
export OS_AUTH_TOKEN=gAAAAABjsYvUCXdVOkJo6EttO7WIVKrqnkbc2_nUU59RGBbzsOo4rbSra5RayTBtC_CJzosiJzZkOj77_nqLt-NcaShU47ggANr8dm9TGvHTY48mphfnZPRyAuFFEr4LiG7zNlJBkOxqbBPR7kDbJIpuVKTodupASxhQAYgaKP0s20zE4C77kC8
When using the SwiftClient tool, it's possible to omit exporting OS_STORAGE_URL and OS_AUTH_TOKEN. However, the request time will be longer because for each request or operation, a new token needs to be obtained. Therefore, it is recommended to export these variables for reuse multiple times.
