Example 1: body-parser npm
$ npm install body-parser
Example 2: body-parser node
// Express/Connect top-level generic // This example demonstrates adding a generic JSON and URL-encoded parser as a top-level middleware, which will parse the bodies of all incoming requests. // This is the simplest setup. var express = require('express') var bodyParser = require('body-parser') var app = express() // parse application/x-www-form-urlencoded app.use(bodyParser.urlencoded({ extended: false })) // parse application/json app.use(bodyParser.json()) app.use(function (req, res) { res.setHeader('Content-Type', 'text/plain') res.write('you posted:\n') res.end(JSON.stringify(req.body, null, 2))})
Example 3: bodyparser purpose
//body-parser helps parse json files //you can use body-parser anytime you need to use a form to post //data to a request var bodyParser = require("body-parser"); app.use(bodyParser.urlencoded({extended: true}));
Example 4: body parser
var express = require('express') var bodyParser = require('body-parser') var app = express() // parseapplication/x-www-form-urlencoded app.use(bodyParser.urlencoded({ extended: false })) // parse application/json app.use(bodyParser.json()) app.use(function (req, res) { res.setHeader('Content-Type', 'text/plain') res.write('you posted:\n') res.end(JSON.stringify(req.body, null, 2))})
Example 5: body parser
<script> const bodyParser = require("body-parser"); app.use(bodyParser.urlencoded({extended:true})); app.post("/", function(req, res){ let firstName = req.body.fNAME; }); </script> <input type="text" name="fNAME" placeholder="First Name">
