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
federationFromUserId	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	Require	Default	Limitation	Description
userId	string	✓		~ 128 chars	User Id
timeOffset	int	✓	0	~ 31536000	Time offset from current time(in seconds)
timeOffsetToken	string			~ 1024 chars	Time offset token

Result

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

federation

Obtains an access token to act as another user ID based on the specified user ID. When issuing a transaction using this access token, the #{userId} in the transaction action is replaced with the user ID in the federation, and the #{originalUserId} is replaced with the user ID in the federation source.

By specifying a policy document, you can set stricter constraints on the permissions that the credentials have as a federated user when calling the API.

Request

	Type	Require	Default	Limitation	Description
originalUserId	string	✓		~ 128 chars	User Id
userId	string	✓		~ 128 chars	User Id
policyDocument	string			~ 1048576 chars	Policy document
timeOffset	int	✓	0	~ 31536000	Time offset from current time(in seconds)
timeOffsetToken	string			~ 1024 chars	Time offset token

Result

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

issueTimeOffsetTokenByUserId

Obtains a time offset token that can be used with the specified user ID.

A time offset token can be used to pseudo-advance the time for API processing by specifying the user ID in APIs that do not require an access token. If you want to use a time offset with an API that uses an access token, you can specify the time offset when issuing the access token to execute the equivalent processing without specifying the token for each request.

Request

	Type	Require	Default	Limitation	Description
userId	string	✓		~ 128 chars	User Id
timeOffset	int	✓	0	~ 31536000	Time offset from current time(in seconds)
timeOffsetToken	string			~ 1024 chars	Time offset token

Result

	Type	Description
token	string	Time offset token
userId	string	User Id
expire	long	effective date
