Learning nodejs and trying to post a form from HTML (with image upload) to nodejs (express) but the request.body returning empty object.
Tried few solutions on this site but no one is working.
Here is my code for creating a dynamic form. (HTML)
function show(data) {
const d = data.temp_form;
let content = ''
// console.log(d)
d.forEach((item) => {
if (item === 'image_backup' || item === 'image_banner') {
content += `<label for='${item}'>${item}</label><input name='${item}' type='file' id='${item}' value=''><br/>`
}else{
content += `<label for='${item}'>${item}</label><input name='${item}' type='text' id='${item}' value=''><br/>`
}
})
content += ` <input type="submit" id="handle_submit">`
getFormContianer.innerHTML = content
}
Code handling form submit
async function handleForm(e) {
e.preventDefault();
let dataForm = new FormData(e.target)
let obj = {}
dataForm.forEach((value, key) => {
obj[key] = value
if( typeof value === 'object'){
console.log(value.name)
obj[key] = value.name
}
});
let data = JSON.stringify(obj);
await fetch(file_api, {
method: 'POST',
body: data
}).then((res)=>{
return res.json();
}).then((data)=>{
console.log('api err: '+data);
}).catch((err) =>{
console.log('api err: '+ err)
})
}
Then, in my nodejs
const express = require('express');
const cors = require('cors');
const config = require('./config')
var bodyParser = require('body-parser');
var multer = require('multer');
var upload = multer();
const app = express()
const templates = require('./routes/templates-routes');
const files = require('./routes/files-routes');
app.use(cors());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(upload.array());
app.use(express.static('public'))
app.use('/api', templates.routes);
app.use('/create', files.routes);
app.listen(config.port, () => {
console.log(`Example app listening at http://localhost:${config.port}`)
})
and in the route.js
const express = require('express');
const router = express.Router();
const {replaceValue } = require('../controllers/filesController');
router.post('/file', replaceValue);
module.exports={
routes: router
}
for the fileController.js
const replaceValue = (request, response) =>{
console.log(request.body)
response.send(request.body)}
Hope that can get some comment for you, thank you so much!
