Javascript中的动态路由-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

当您获得诸如www.domain / route / other-page之类的URL时，通过进行一些正则表达式操作，就可以从字符串中获取字符串“ route”和“ other-page”，并将其转换为“ Route”和“ ohterPage”并填充它们放入$ controller和$ action变量中，您只需调用'$ controller-> $ action（）;' 它将调用Route-> otherPage（）来提供请求的模板

这是一个很不错的解决方案，因为当您说出40种不同的操作（例如提供模板和各种get和post请求）时，您仅需添加5条路由即可处理该问题，但是您需要像上面那样动态引用该对象和方法。 ...有没有办法在javascript中实现这一目标？

谢谢

为此使用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')
})
