ctx.throw response

See original GitHub issue

Hey guys, I saw your response for ctx.throw not supporting a custom response in #194. however I noticed, that it only errors and forces the body when you throw a 500. If I use ctx.throw(400, JSON.stringify({some: "data"})) it works just fine.

Any chance you would re-consider allowing custom responses for 500 errors too?

What @AliasT suggested worked.

I didn’t open that one, I just responded to it. But I wanted koa to return a 500 error, have ctx.body be JSON so that the service that is consuming it could print useful errors to the customer.

I Want to use ctx.throw because that stops the request immediatly and doesn’t traverse through any other middleware.

this might work:

ctx.throw(500, JSON.stringify({some: "data"}), { expose: true })

but it seems like this feature is just designed for user-level error https://github.com/koajs/koa/blob/master/lib/context.js#L70
