Javascript中的動態路由-Node.js

Question

因此，在php中，您可以像

class Route
{
  public function homePage ()
  {
    echo 'You are on the home page'
  }

  public function otherPage ()
  {
    echo 'You are on some other page'
  }
}

class Route2
{
  public function homePage ()
  {
    echo 'You are on the home page'
  }

  public function otherPage ()
  {
    echo 'You are on some other page'
  }
}
// when you get the url like www.domain/route/other-page, with some regex operation you get out as string 'route' and 'other-page' from the route transform it to 'Route' and 'ohterPage' and fill them into the $controller and action variables and you just call:
$controller->$action();
// and it will call Route->otherPage() which will serve up the requested template

當您獲得諸如www.domain / route / other-page之類的URL時，通過進行一些正則表達式操作，就可以從字符串中獲取字符串“ route”和“ other-page”，並將其轉換為“ Route”和“ ohterPage”並填充它們放入$ controller和$ action變量中，您只需調用'$ controller-> $ action（）;' 它將調用Route-> otherPage（）來提供請求的模板

這是一個很不錯的解決方案，因為當您說出40種不同的操作（例如提供模板和各種get和post請求）時，您僅需添加5條路由即可處理該問題，但是您需要像上面那樣動態引用該對象和方法。 ...有沒有辦法在javascript中實現這一目標？

謝謝

為此使用Express Js：

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

// respond with "hello world" when a GET request is made to the homepage
app.get('/', function (req, res) {
  res.send('hello world')
})
