How to process POST data in Node js

0 votes

How do you extract form data (form[method="post"]) and file uploads sent from the HTTP POST method in Node.js?

function (request, response) {
    //request.post????
}

Is there a library?

Hello @kartik,

You can use the querystring module:

var qs = require('querystring');

function (request, response) {
    if (request.method == 'POST') {
        var body = '';

        request.on('data', function (data) {
            body += data;

            // Too much POST data, kill the connection!
            // 1e6 === 1 * Math.pow(10, 6) === 1 * 1000000 ~~~ 1MB
            if (body.length > 1e6)
                request.connection.destroy();
        });

        request.on('end', function () {
            var post = qs.parse(body);
            // use post['blah'], etc.
        });
    }
}

Now, for example, if you have an input field with name age, you could access it using the variable post:

console.log(post.age);

Hope it helps!!

Thank you!!
