Bug: koa-body Sets ctx.request.body to {} by Default, Preventing Proper Parsing

Line 109 in c93a643

{},

Description

koa-body sets ctx.request.body = {} even when no body is parsed (index.ts#L109). This prevents other middleware from correctly determining whether a request body exists.

For example, koa-bodyparser (index.js#L64) only parses the request if ctx.request.body is undefined. Since koa-body sets it to {}, koa-bodyparser skips parsing, causing unexpected behavior.

Expected Behavior

If no body is parsed, ctx.request.body should remain undefined so that downstream middleware (including koa-bodyparser) can handle it appropriately.

Steps to Reproduce

Use koa-body in a Koa app.
Send a request without a body (e.g., a GET request or an empty POST request).
Observe that ctx.request.body is {} instead of undefined, which may prevent other middleware from handling the request properly.

Possible Fix

Avoid setting "{}" when the request body is not parsed.
