Hooks 中间件设计

api-config.ts

export const config =  {
  middleware: [
    async (next) => {
      const ctx = useContext()
      ctx.name = ctx.request.body.name
      await next()
    }
  ]
}

export default async () => {
  const ctx = useContext()
  return ctx.name
}

api.ts

export default withController({
  middleware: [
    async (next) => {
      const ctx = useContext()
      ctx.name = ctx.request.body.name
      await next()
    }
  ]
}, () => {
  const ctx = useContext()
  return ctx.name
})

configuration.ts

import { hooks, createConfiguration } from '@midwayjs/hooks'
import { Application } from '@midwayjs/koa'
import bodyParser from 'koa-bodyparser'

export default createConfiguration({
  imports: [
    hooks({
      middleware: [
        bodyParser(),
        async (ctx, next) => {
          ctx.name = ctx.request.body.name
          await next()
        }
      ]
    })
  ],
})
