req.query and req.param in ExpressJS

by

req.query will return a JS object after the query string is parsed.

/user?name=tom&age=55 – req.query would yield {name:"tom", age: "55"}

req.params will return parameters in the matched route.
If your route is /user/:id and you make a request to /user/5 – req.params would yield {id: "5"}

req.param is a function that peels parameters out of the request. All of this can be found here.

UPDATE

If the verb is a POST and you are using bodyParser, then you should be able to get the form body in you function with req.body. That will be the parsed JS version of the POSTed form.
