To generate agora token, we need a simple express application.
$ npm init -yThis will initialize a basic package.json file. Now, install the dependecies.
$ npm install express agora-token-generator dot-env
Now, create a basic express application. In server.js file put the following code.
const express = require("express");
const app = express();
require("dotenv").config();
app.get("/", (req, res) => {
res.sendStatus(200);
});
const PORT = process.env.PORT || 5000;
app.listen(PORT, () => {
console.log(`App is running on port ${PORT}`);
});Now, we will test the server in localhost. Run,
$ node server.js
Our server is running on PORT 5000. If we ping localhost:5000, we will get a 200 OK status.
Now, import agora-token-generator on our server.
const {
RtmTokenBuilder,
RtmRole,
RtcTokenBuilder,
RtcRole,
} = require("agora-access-token");Finally add some route for different tokens. Here I create some route for tokens.
const generateRtmToken = (account) => {
const appID = process.env.appID;
const appCertificate = process.env.appCertificate;
const expirationTimeInSeconds = 3600;
const currentTimestamp = Math.floor(Date.now() / 1000);
const privilegeExpiredTs = currentTimestamp + expirationTimeInSeconds;
return RtmTokenBuilder.buildToken(
appID,
appCertificate,
account,
RtmRole,
privilegeExpiredTs
);
};
const generateRtcToken = (account, channelName = "testChannel") => {
const appID = process.env.appID;
const appCertificate = process.env.appCertificate;
const expirationTimeInSeconds = 3600;
const currentTimestamp = Math.floor(Date.now() / 1000);
const privilegeExpiredTs = currentTimestamp + expirationTimeInSeconds;
return RtcTokenBuilder.buildTokenWithAccount(
appID,
appCertificate,
channelName,
account,
RtcRole,
privilegeExpiredTs
);
};
const generateRtcUidToken = (uid, channelName = "testChannel") => {
const appID = process.env.appID;
const appCertificate = process.env.appCertificate;
const expirationTimeInSeconds = 3600;
const currentTimestamp = Math.floor(Date.now() / 1000);
const privilegeExpiredTs = currentTimestamp + expirationTimeInSeconds;
const rtcUidToken = RtcTokenBuilder.buildTokenWithUid(
appID,
appCertificate,
channelName,
uid,
RtcRole,
privilegeExpiredTs
);
return rtcUidToken;
};
app.get("/rtc-uid-token", (req, res) => {
const uid = req.query.uid;
const channelName = req.query.channelName;
const rtcUidToken = generateRtcUidToken(uid, channelName);
res.status(200).json({ token: rtcUidToken });
});
app.get("/rtm-token", (req, res) => {
const account = req.query.username;
const rtmToken = generateRtmToken(account);
res.status(200).json({ token: rtmToken });
});
app.get("/rtc-token", (req, res) => {
const account = req.query.username;
const channelName = req.query.channelName;
const rtcToken = generateRtcToken(account, channelName);
res.status(200).json({ token: rtcToken });
});For ping different route to get tokens.
