Reading the Post Parameters in NodeJS: -------------------------------------- - "req" is the predefined object provided by node engine. - "req" object used to handle both "get" & "post" parameters. - "req" object divided into two parts. 1. header 2. body - all the post parameters saved into req object "body" part. - "body" is the predefined property used to read the post parameters. - "body" property available on "body-parser module".

Ex. http://localhost:8080/userDetails/adm... app.get("/userDetails/:uname/:upwd", function(req,res){ if(req.params.uname == "admin" && req.params.upwd == "admin"){ res.send({"login":"success"}); }else{ res.send({"login":"fail"}); } }); Ex. http://localhost:8080/userDetails?una... - "url" is the predefined module in node js. - "url" module used to read the get parameters. var express = require("express"); var url = require("url"); var bodyparser = require("body-parser"); var app = express(); app.use(bodyparser.json()); app.get("/userDetails" , function(req,res){ var obj = url.parse(req.url,true).query; if(obj.uname == "admin" && obj.upwd == "admin"){ res.send({"login":"success"}); }else{ res.send({"login":"fail"}); } });
