GS2-Auth SDK for Game Engine API Reference

Specifications of models and API references for GS2-Auth SDK for Game Engine

Model

EzAccessToken

Access token

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

	Type	Required	Default	Value Limits	Description
token	string	✓		~ 1024 chars	Access token A token used to authenticate access. This token is automatically generated by the system and identifies the user’s session.
userId	string	✓		~ 128 chars	User ID
expire	long		The absolute time 1 hour after the current time		Expiration time A timestamp indicating the expiration time of the token. When this date is reached, the token becomes invalid. Unix time, milliseconds

Methods

Pass the body and signature obtained from GS2-Account::Authentication to log in and receive an access token. The access token is a temporary login credential valid for 1 hour, and is required to use GS2 services as a specific player.

In most cases, you do not need to call this API directly. The Unity and Unreal Engine 5 SDKs provide Profile::Login, which combines GS2-Account::Authentication and this API into a single call. See Initialization / Game Engine for details.

Request

	Type	Required	Default	Value Limits	Description
keyId	string		“grn:gs2:{region}:{ownerId}:key:default:key:default”	~ 1024 chars	Encryption Key GRN
body	string	✓		~ 524288 chars	Signed authentication payload
signature	string	✓		~ 1024 chars	Signature

Result

	Type	Description
token	string	Access token A token used to authenticate access. This token is automatically generated by the system and identifies the user’s session.
userId	string	User ID
expire	long	Expiration time A timestamp indicating the expiration time of the token. When this date is reached, the token becomes invalid. Unix time, milliseconds

Implementation Example

    var domain = gs2.Auth.AccessToken(
    );
    var result = await domain.LoginAsync(
        body: "body",
        signature: "signature",
        keyId: "key-0001"
    );
    var token = result.Token;
    var userId = result.UserId;
    var expire = result.Expire;

    var domain = gs2.Auth.AccessToken(
    );
    var future = domain.LoginFuture(
        body: "body",
        signature: "signature",
        keyId: "key-0001"
    );
    yield return future;
    if (future.Error != null)
    {
        onError.Invoke(future.Error, null);
        yield break;
    }
    var token = future.Result.Token;
    var userId = future.Result.UserId;
    var expire = future.Result.Expire;

    const auto Domain = Gs2->Auth->AccessToken(
    );
    const auto Future = Domain->Login(
        "body", // body
        "signature", // signature
        "key-0001" // keyId
    );
    Future->StartSynchronousTask();
    if (Future->GetTask().IsError())
    {
        return false;
    }
    const auto Result = Future->GetTask().Result();
    const auto Token = Result->Token;
    const auto UserId = Result->UserId;
    const auto Expire = Result->Expire;
