Подскажите пожалуйста, почему мне не удается подключить и использовать express.bodyParser? Как я могу это сделать?
app.use(express.static(__dirname + '/dist'));
app.use(todoRoutes);
function start (){
try {
app.listen(PORT, () =>{
console.log("Server has been statred...")
});
}
catch(e){
console.log(e);
}
}
start();
const {Router} = require('express');
const router = Router();
var foo = require("../script.js");
router.configure(function(){
router.use(express.bodyParser());
});
const path = require('path');
var myModule = require('../index.js');
router.get('/', (req, res)=> {
res.sendFile(path.resolve('./dist/index.html'));
});
router.post('/1',(req, res) =>{ // отправка первого экрана
console.log("POST");
res.sendFile(path.resolve('./data/firstScreen.json'));
})
router.post('/2',(req, res) =>{ // отправка второго экрана
console.log("POST");
res.sendFile(path.resolve('./data/secondScreen.json'));
})
router.post('/currentDir1', (req, res) =>{
console.log("POST");
let body = "";
let pathToFile = "";
console.log(req.body);
req.on("data", function (data) {
body += data;
});
req.on("end", function(currentData) {
console.log(JSON.parse(body));
currentData = JSON.parse(body);
if(currentData.sizeOrType === "<папка>"){
let dir = currentData.dir + currentData.fileName;
// dir = "C:\totalcmd";
console.log(dir);
if(currentData.whichScreen){
console.log(currentData.whichScreen);
console.log("ggg");
foo(dir, './data/firstScreen.json');
pathToFile = './data/firstScreen.json';
res.sendFile(path.resolve('./data/firstScreen.json'));
}else{
console.log('aaaa');
foo(dir, './data/secondScreen.json');
pathToFile = './data/firstScreen.json';
res.sendFile(path.resolve('./data/secondScreen.json'));
}
}
// // res.json({ message: 'goodbye'})
res.sendFile(path.resolve('./data/firstScreen.json'));
});
// res.sendFile(path.resolve(pathToFile));
})
module.exports = router;
Если посмотреть документацию
то есть несколько примеров использования
пример с Express/Connect top-level generic
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))
})
Express route-specific
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
// create application/json parser
var jsonParser = bodyParser.json()
// create application/x-www-form-urlencoded parser
var urlencodedParser = bodyParser.urlencoded({ extended: false })
// POST /login gets urlencoded bodies
app.post('/login', urlencodedParser, function (req, res) {
res.send('welcome, ' + req.body.username)
})
// POST /api/users gets JSON bodies
app.post('/api/users', jsonParser, function (req, res) {
// create user in req.body
})
у Вас думаю начало будет примерно так
const {Router} = require('express');
const router = Router();
var foo = require("../script.js");
var bodyParser = require('body-parser')
//router.configure(function(){
// router.use(express.bodyParser());
//});
// parse application/json
router.use(bodyParser.json())
