Player access to Vivox resources is controlled through Vivox access tokens. Vivox access tokens contain a payload that defines the privileged operation, are signed by the game server by using a token signing key, and are delivered by the client to the Vivox system when the player wants to perform a privileged operation. A Vivox access token is similar to a JSON Web Token, but instead has an empty access token header.
注意
Vivox Access Tokens are an optional, and advanced, feature for managing player channel access. Unity Authentication tokens are the recommended way to manage players when channel access control isn't required. The Authentication SDK for Unreal Engine is available as part of the Unity Gaming Services SDK plug-in for Unreal Engine.
Access tokens have the following characteristics:
-
You can only use atoken once. After you use a token for the privileged operation, it cannot be reused.
-
Tokens expire even if they are never used. You cannot use a token after the expiration time that is set by the token issuer.
Game clients require access tokens to perform operations in the Vivox system.
- Game client-generated tokens - use for prototyping or testing purposes
- Secure game server-generated tokens - use for the secure deployment of a production game and to avoid token errors due to user time settings
Note that before either a client or a server can generate a token, you need a token issuer and a token signing key.

The following diagram displays a typical interaction between a game client, the game server, and the Vivox system:
