API Reference of GS2-Auth SDK

Model

AccessToken

Access token

A model that manages access tokens issued after user authentication. Access tokens are used to identify the identity of a session while a user is logged in to the service. Tokens have an expiration date, and when they expire, re-authentication is required.

	Type	Require	Default	Limitation	Description
token	string	✓		~ 1024 chars	Access token
userId	string	✓		~ 128 chars	User Id
expire	long	✓	Difference from current time(1 hours)	Expiration date
timeOffset	int	✓	0	~ 31536000	Time offset from current time(in seconds)

Methods

Logs into GS2 with the specified user ID and obtains an access token This API is intended to be called from a trusted game server. It is inappropriate to call it from the client, as there is no validation process for the user ID value.

Request

	Type	Condition	Require	Default	Limitation	Description
userId	string		✓		~ 128 chars	User Id
timeOffset	int		✓	0	~ 31536000	Time offset from current time(in seconds)

Result

	Type	Description
token	string	access token
userId	string	User Id
expire	long	effective date
