Why does req.params return an empty array?

Question

I'm using Node.js and I want to see all of the parameters that have been posted to my script. To get to my function, in my routes/index.js I'm doing:

app.post('/v1/order', order.create); 

Then in my function, I have:

exports.create = function(req, res, next) {  console.log( req.params ); 

But it's returning an empty array. But when I do:

exports.create = function(req, res, next) {  console.log( req.param('account_id') ); 

I get data. So I'm a bit confused as to what's going on here.

Answer 1

req.params
can only get the param of request url in this pattern:/user/:name

req.query
get query params(name) like /user?name=123 or body params.
