Now we will implement an API which will be called using user ID and it will display the detail of the corresponding user.<\/p>\n
server.js<\/p>\n
var express = require(‘express’);<\/p>\n
var app = express();<\/p>\n
var fs = require(“fs”);<\/p>\n
app.get(‘\/:id’, function (req, res) {<\/p>\n
\/\/ First read existing users.<\/p>\n
fs.readFile( __dirname + “\/” + “users.json”, ‘utf8’, function (err, data) {<\/p>\n
var users = JSON.parse( data );<\/p>\n
var user = users[“user” + req.params.id]\n
console.log( user );<\/p>\n
res.end( JSON.stringify(user));<\/p>\n
});<\/p>\n
})<\/p>\n
var server = app.listen(8081, function () {<\/p>\n
var host = server.address().address<\/p>\n
var port = server.address().port<\/p>\n
console.log(“Example app listening at http:\/\/%s:%s”, host, port)<\/p>\n
})<\/p>\n
Now try to access defined API using URL: http:\/\/127.0.0.1:8081\/2 and HTTP Method : GET on local machine using any REST client. This should produce following result \u2212<\/p>\n
