How to tell if a request doesn't have a body?

[mike-zorn]

I use the json parser as middleware in an express app, but for all requests (even with Content-Type: text/plain), the parser will set req.body to an empty object, so I can't use that to see if the request has a body. The json parser sets req.body before deciding to parse it. What's the best way to determine whether or not a request has a body when using this middleware?
