How to get request body with customize token? about koa-log4js HOT 6 OPEN

You can pass the replacement as a replace function.

tokens: [
  { token: ':body', replacement: function() { return ctx.request.body } }
]

from koa-log4js.

But it seems can't use as Koa-middleware way,
such as

app.use(log4js.koaLogger(log4js.getLogger('http'), { level: 'auto', tokens: [
  { token: ':body', replacement: function() { return ctx.request.body } }
] }))

because ctx is not defined here.

from koa-log4js.

I have just added a new syntax to allow replacing token with ctx.

tokens: [
  { token: ':body', content: function(ctx) { return ctx.request.body } }
]

You can upgrade your package to v1.1.0 (for Koa v1) or v2.1.0 (for Koa v2).

Wonderful.

Now I use { token: ':body', content: function(ctx) { return JSON.stringify(ctx.request.body) } } log the body'

from koa-log4js.

It not work, it save the first time request param, and return it everytime

from koa-log4js.

Which should be fix by this #8 PR.
