}
nodejs web integration
It contains jwt generation and simple and based on the official nodejs sdk demo (integrated sockjs)
- package.json
{
"name": "web",
"version": "1.0.0",
"main": "index.js",
"license": "MIT",
"dependencies": {
"centrifuge": "^2.2.1",
"jsonwebtoken": "^8.5.1",
"sockjs-client": "^1.3.0"
},
"scripts": {
"s":"node app.js"
}
}
- app.js
var Centrifuge = require("centrifuge")
var SockJS = require('sockjs-client');
var jwt = require('jsonwebtoken');
var token = jwt.sign({ sub: 'dalongdemo'}, '05f0842d-c302-4036-a19f-6ac263b9f620');
var centrifuge = new Centrifuge("http://localhost:8000/connection/sockjs", {
sockjs: SockJS
})
Centrifuge. SetToken ( Token)
centrifuge.subscribe("news", function(message) {
console.log(message);
});
centrifuge.connect();
&& test run
- Start Service
docker-compose up -d
- Start nodejs demo application
cd web
yarn
yarn s
- Dissemination of information through api
curl -X POST \
http://localhost:8000/api \
-H 'Authorization: apikey cbf46e80-3e00-4642-8f3a-369b8707304d' \
