Question

如何为koajs分隔trie-route的路线？

app.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)

路由/ 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()

路由/ 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()

当我尝试在http://127.0.1.1:3000/上发布邮寄给我时：

Method Not Allowed

任何想法如何解决这个问题？

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呼叫app.use()优先于下一次呼叫。例如，如果我改为：

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

然后我在GET请求中得到了相同的错误。为了实现这一点，我所做的是从routes/get.js和routes/post.js返回实际的路由器，然后在app.js中配置中间件。

所以在routes/get.js和routes/post.js -

中

而不是：

module.exports = router.middleware()

导出：

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)
