What does the bodyParser() in connect middleware do?
node.js, node.js-connect
Solution
It populates `req.body` with (among other things) the value of the `POST` parameters. Here's the doc and examples: http://expressjs.com/api.html#req.body
bodyParser is a part of "Connect", a set of middlewares for node.js. Here's the real docs and source from Connect: http://www.senchalabs.org/connect/bodyParser.html
As you can see, it's simply a thin wrapper that tries to decode JSON, if fails try to decide URLEncoded, and if fails try to decode Multi-Part.
Problem
I'm doing a tutorials on node.js, and the lesson is teaching me how to create a server using node. In the code below, what does the connect.bodyParser() line do? ``` var app = connect() .use(connect.bodyParser()) .use(connect.static('public')) .use(function (req, res) { if (req.url === '/process') { res.end(req.body.name + ' would repeat ' + req.body.repeat + ' times.'); } else { res.end("Invalid Request"); } }) .listen(3000); ```
