Node.js (with express & bodyParser): unable to obtain form-data from post request

In general, an express app needs to specify the appropriate body-parser middleware in order for req.body to contain the body.

[EDITED]

  1. If you required parsing of url-encoded (non-multipart) form data, as well as JSON, try adding:

    // Put this statement near the top of your module
    var bodyParser = require('body-parser');
    
    
    // Put these statements before you define any routes.
    app.use(bodyParser.urlencoded());
    app.use(bodyParser.json());
    

    First, you'll need to add body-parser to the dependencies property of your package.json, and then perform a npm update.

  2. To handle multi-part form data, the bodyParser.urlencoded() body parser will not work. See the suggested modules here for parsing multipart bodies.


To handle multipart/form-data request that support file upload, you need to use multer module. npm link for multer middleware


I followed this https://www.tutorialspoint.com/expressjs/expressjs_form_data.htm

var bodyParser = require('body-parser');
var multer = require('multer');
var forms = multer();

// apply them

app.use(bodyParser.json());
app.use(forms.array()); 
app.use(bodyParser.urlencoded({ extended: true }));

// how to use

router.post('/', function(req, res) {
    console.log(req.body);
    console.log('received the widget request');
});

Make sure to put in this order: bodyParser.json() first. app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: true }));
