Generate token using an app server

Interactive Whiteboard uses a set of tokens for user authentication: SDK Tokens, Room Tokens, and Task Tokens. Each type of token can be assigned to an admin, writer, or reader role. For details, see Token Overview.

Agora provides an open source netless-token repository on GitHub that includes code samples for generating tokens using JavaScript, TypeScript, Java, Golang, PHP, Ruby, and C#.

This article introduces how to generate tokens from your app server using these code samples and your access keys (the AK and SK).

To enhance security, do not save or send the AK and SK to your app clients. You should save the AK and SK on the app server, and issue tokens from the app server according to the actual needs of your app scenarios.

Prerequisites

Ensure that you have enabled Interactive Whiteboard for your Agora Console project.

JavaScript

In the netless-token-master/Node/JavaScript folder, you can find:

An index.js file, which contains the source code for generating tokens.
A README.md file, which contains code samples for generating tokens.

Before proceeding, ensure that you have installed the latest version of Node.js LTS.

Generate an SDK Token

Refer to the following steps to generate an SDK Token:

Download the netless-token repository or clone it to a local directory.
Go to the netless-token-master/Node/JavaScript folder and run the following command to install Node.js dependencies:

npm install

Create a file named sdktoken.js and copy the following code into it:

const  { sdkToken, TokenPrefix } = require("./index");
// Generate a SDK Token
const netlessSDKToken = sdkToken(
   "Your AK", // Fill in the AK you get from Agora Console 
   "Your SK", // Fill in the SK you get from Agora Console
   1000 * 60 * 10, // Token validity period in milliseconds. If you set it to 0, the token will never expire 
      {
       role: 0 // Define the permissions granted by the token. You can set it to 0 (Admin), 1 (Writer), or 2 (Reader) 
      }
);
console.log(netlessSDKToken)
