EasyPost

An example of reading POST data in node.js. View the full tutorial at http://www.primaryobjects.com/CMS/Article144.aspx

This example shows how to read POST data from both a form submission, and a REST client. The code example uses a manager method. This helps abstract the extra work of using res.on('data') and res.on('end'). It also provides a single location for maintaing the code that reads POST data, allowing you to enhance it, such as with checks for flooding attacks, etc.

We'll cover reading data from a form submissions and reading data submitted through a REST client (ie., streamed).

Demo @ http://easypost.herokuapp.com

 

Reading POST Data From a Form

    CommonManager.getPostData(req, res, function (data) {

        res.render('index', { txtName: data.txtName });

    });

Reading POST Data From a REST Client

    CommonManager.getPostData(req, res, function (data) {

        data = JSON.parse(data);

        res.render('index', { txtName: data.txtName });

    });

The core manager method for reading the POST data is located in commonManager.js:

CommonManager = {

    getPostData: function (req, res, callback) {

        // Check if this is a form post or a stream post via REST client.

        if (req.readable) {

            // REST post.

            var content = '';

            req.on('data', function (data) {

                if (content.length > 1e6) {

                    // Flood attack or faulty client, nuke request.

                    res.json({ error: 'Request entity too large.' }, 413);

                }

                // Append data.

                content += data;

            });

            req.on('end', function () {

                // Return the posted data.

                callback(content);

            });

        }

        else {

            // Form post.

            callback(req.body);

        }

    }

}
