const Koa = require('koa')
const route = require('koa-route')
const bodyParser = require('koa-bodyparser')

const app = new Koa()

app.use(bodyParser({
    enableTypes: ['json', 'form', 'text']
}))

const main = ctx => {
    ctx.cookies.set('mycookie', 'hello-value');
    console.log(ctx.cookies.get('mycookie'))
    // 奇怪，这里为什么输出 undefined 呢?
    
    ctx.response.type = 'html'
    ctx.response.body = '<a href="/">main Page</a>'
}

app.use(route.get('/', main))
app.listen(8090, '0.0.0.0', () => {
    console.log('Example app listening on http://localhost:8090/')
})

问题

这里明明设置了cookie,但是输出 undefined ? 用浏览器就能正常的输出 hello-value

   ctx.cookies.set('mycookie', 'hello-value');
   console.log(ctx.cookies.get('mycookie'))
   console.log(ctx.cookies.get('mycookie')
