如何使用koajs的trie-route分隔路线？

应用程序.js：

const Koa = require('koa')
const get = require('./routes/get')
const post = require('./routes/post')

const app = new Koa()

app.use(get)
app.use(post)
app.listen(3000)

路线/get.js：

'use strict'

const Router = require('koa-trie-router')

const router = new Router()

// middleware that is specific to this router
router.use(async (ctx, next) => {
  console.log('Time: ', Date.now())
  await next()
})

// define the home page route
router.get('/', async (ctx, next) => {
  ctx.type = 'json'
  ctx.body = {
    message: 'Birds home page'
  }
})

// Separate this post route in a new file.
// router.post('/', async (ctx, next) => {
//   ctx.type = 'json'
//   ctx.body = {
//     message: 'Post birds home page'
//   }
// })

module.exports = router.middleware()

路线/post.js：

'use strict'

const Router = require('koa-trie-router')

const router = new Router()

router.post('/', async (ctx, next) => {
  ctx.type = 'json'
  ctx.body = {
    message: 'Post birds home page'
  }
})

module.exports = router.middleware()

当我尝试将其发布在我的邮递员上时http://127.0.1.1:3000/：

Method Not Allowed

有什么想法可以解决这个问题吗？

我的 package.js：

{
  "name": "basic",
  "version": "1.0.0",
  "description": "basic sample",
  "main": "app.js",
  "author": "xxx",
  "license": "BSD-2-Clause",
  "dependencies": {
    "koa": "^2.3.0",
    "koa-trie-router": "^2.1.5"
  },
  "keywords": [
    "kao",
    "nodejs"
  ]
}

您看到的问题是由于第一次调用app.use()优先于下一次调用。例如，如果我改为执行以下操作：

app.use(post)
app.use(get)

然后我得到了同样的错误，但在GET请求中。为了让它工作，我所做的是从routes/get.jsand返回实际的路由器routes/post.js，然后在app.js.

所以在你routes/get.js和routes/post.js-

代替：

module.exports = router.middleware()

出口：

module.exports = router

在app.js：

const Koa = require('koa')
const get = require('./routes/get')
const post = require('./routes/post')

const Router = require('koa-trie-router')

const router = new Router()

router.get(get.middleware());
router.post(post.middleware());

const app = new Koa()
app.use(router.middleware());
app.listen(3000)
