在运行时添加路由（ExpressJs） [英] Add Routes at Runtime (ExpressJs)

问题描述

我想在运行时添加路由。我读过这是可能的，但我不确定如何做到。目前，我使用以下代码：

I would like to add routes at run time. I read that its possible but I am not so sure how. Currently I using the following code:

var app = express();

function CreateRoute(route){
app.use(route, require('./routes/customchat.js'));
}

自定义聊天看起来像

var express = require('express');
var router = express.Router();

router.route('/').get(function (req, res) {
var url =  req.baseUrl;
var roomname = url.substring(url.lastIndexOf('_') + 1);
res.render('chat', { name: roomname , year: new Date().getFullYear().toString()});
});

module.exports = router;

当我在开始监听之前调用CreateRoute方法时，它将链接该路由。但是，当我在运行时执行此操作时，它不会创建新的路由。
我的目标是添加路由并添加运行时。我将生成类似/ room_Date的路径。这应该在运行时使用模板customchat添加。

When I call the method CreateRoute before I start listening it will link the route. But when I do it at runtime it wont create a new route. My goal is to add routes add runtime. I will generate an path like /room_Date. And this should be added at runtime using the template customchat.

我使用的是Express版本4.13。

I am using express version 4.13.

谢谢

推荐答案

customchat.js 应该称为 customChat.js 并成为

const customChat = (req, res) => {
  const { name } =  req.params;
  const year = new Date().getFullYear().toString();
  res.render('chat', { name , year });
}

module.exports = customChat

然后当您创建您的应用

const express = require('express')
const customChat = require('./routes/customChat.js')
const app = express()

app.use('/chat/:name', customChat)

请参见官方Express路由文档以获取更多信息。
