Generate a Token at App Server

Agora 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).

Prerequisites

Ensure that you have enabled the whiteboard service 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.

   "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) 
      }

         // Fill in the AK you get from Agora Console 
         "ak",
         // Fill in the SK you get from Agora Console 
         "sk",
         // Set the Token validity period. If you set it to 0, the token will never expire
         1000 * 60 * 10,
         // Define the permissions granted by the token. You can set it to TokenRole.Admin, TokenRole.Writer, or TokenRole.Reader 
         // Fill in the Task UUID. You can get it by calling the RESTful API to start a file-conversion task 
         new TaskContent(TokenRole.Admin, "Your Task UUID")
         ); 
     Console.WriteLine(token);
 }
}
