暴露在Nodejs的路由器文件中创建对象 [英] Expose vs Creating object in Router file of Nodejs

问题描述

所以，我刚开始使用 expressjs 4.0.0 ，并碰到 express.Router（）这是非常好的。

So, I just started with expressjs 4.0.0 and came across the express.Router() object, which is really nice.

问题是，现在我所有的路线都在另一个文件中，如何将对象公开到路由文件？

Problem is, now that all my routes are in another file, how do I expose an object to the routes file ?

serverjs文件：

serverjs file:

...
var passport = require（'passport'）;
var router = require（'./ app / routes.js'）（护照）; //不会工作
app.use（'/'，路由器）;
app.listen（8080）;

...
var passport = require('passport');
var router = require('./app/routes.js')(passport); //WILL NOT WORK
app.use('/', router);
app.listen(8080);

routes.js文件：

routes.js file:

...
var express = require（'express'）;

var router = express.Router（）; // expressjs 4.0中的新功能

//路由到这里

module.export = router;

...
var express = require('express');
var router = express.Router(); //new feature in expressjs 4.0
//routes go here
module.export = router;

那么我应该如何在路由器文件中访问护照对象？我应该创建一个新对象还是有一种方法将server.js对象传递给router.js文件？

So, how should I access passport object in router file ? Should I create a new object or is there a way to pass the server.js object to router.js file ?

推荐答案

你可以将您的router.js包装在接受护照对象作为参数的函数中，并处理路由器的实例化。然后，module.export功能而不是路由器。

You could wrap your router.js in a function that accepts the passport object as parameter and handles the instantiation of the router also. Then, module.export that function instead of only the router.

编辑：包括示例

server.js ：

server.js:

var passport = require('passport');
var router = require('./app/routes')(app, passport);
app.use('/', router);
app.listen(8080);

routes.js：

routes.js:

var express = require('express');
module.exports = function(app, passport){

   var router = express.Router();

   // routes go here
   // do stuff with passport

   return router;

}
