if nothing was parsed why does ctx.request.body have a value?

If nothing was parsed why does ctx.request.body have a value (empty object)?

In both these cases ctx.request.body equals {}: a) The request body was empty b) The request body was '{}'

How do I distinguish whether the request body was empty or '{}'? What's the recommended method to test whether the request body is empty?

this is by design, so you don't need to check body exists every time.

you can use ctx.request.rawBody to get the original request body string. https://github.com/koajs/bodyparser#raw-body
