"next('route')"不适用于".use()"； [英] "next('route')" doesn't work with ".use()"

问题描述

我在这里做错什么了吗，还是表示只是不支持next('route')和.use()?

Am I doing something wrong here, or does express just not support next('route') with .use()?

var express = require('express')
var app = express()

app.use([
  function (req, res, next) {
    return next('route')
  },
  function (req, res, next) {
    return res.send('sigma')
  },
])

app.use(function (req, res, next) {
  return res.send('alpha')
})

module.exports = app

这将提供字符串sigma，并且应将字符串alpha作为服务器.

This serves the string sigma and should server the string alpha.

更新:只是尝试了一下，但效果不佳.

Update: just tried this and it didn't work as well.

var express = require('express')
var app = express()

app.use('/', [
  function (req, res, next) {
    return next('route')
  },
  function (req, res, next) {
    return res.send('sigma')
  },
])

app.use('/', function (req, res, next) {
  return res.send('alpha')
})

module.exports = app

更新，这也是

var express = require('express')
var app = express()

app.use(function (req, res, next) {
    return next('route')
},
function (req, res, next) {
  return res.send('sigma')
})

app.use(function (req, res, next) {
  return res.send('alpha')
})

module.exports = app

推荐答案

根据节点问题#2591 :由于app.use()定义了中间件，而不是路由"，因此next('route')与app.use()一起使用时毫无意义.

According to the discussion in node issue #2591: since app.use() defines middleware, and not a "route", next('route') is meaningless when used with app.use().
