无法在Express 4.0中将路由拆分为单独的文件(Unable to Split Routes into Separate Files in Express 4.0)

无法在Express 4.0中将路由拆分为单独的文件(Unable to Split Routes into Separate Files in Express 4.0)

我正在尝试将以/api结尾的所有路由重定向到manager.js ，然后将其路由到/me 。

因此，对/me的完全合格的请求应该看起来像/api/me 。 在Express 3.x中，将路由分割成单独的文件很容易，但我在4.0中遇到了麻烦。

app.js

app.use('/api',require('./routes/manager'));

manager.js

var express = require('express'); var manager = express.Router(); module.exports = function() { manager.use('/me',require('../routes/me')); };

me.js

var express = require('express'); var me = express.Router(); module.exports = function() { me.route('/') .get(function(req,res){ res.send("Welcome to Me"); }); };

当我去localhost:8080/api/me ，没有任何反应，页面继续加载。

谢谢你的帮助！

I'm trying to redirect all my routes ending with /api to a manager.js which will then route it to /me.

So, a fully qualified request to /me should look like /api/me. Splitting routes up into separate files was easy in Express 3.x, but I'm having trouble in 4.0.

app.js

app.use('/api',require('./routes/manager'));

manager.js

var express = require('express'); var manager = express.Router(); module.exports = function() { manager.use('/me',require('../routes/me')); };

me.js

var express = require('express'); var me = express.Router(); module.exports = function() { me.route('/') .get(function(req,res){ res.send("Welcome to Me"); }); };

When I go to localhost:8080/api/me, nothing happens, the page keeps loading.

Thanks for any help!

您没有正确地通过Router对象。 请记住，这是您要做的事情：

app.use('/api', express.Router());

但你现在有效地做的是：

app.use('/api', function(){ express.Router() });

因此，您应该导出Router本身，而不是导出功能。

manager.js

var express = require('express'); var manager = express.Router(); manager.use('/me',require('../routes/me')); module.exports = manager;

me.js

var express = require('express'); var me = express.Router(); me.route('/').get(function(req,res){ res.send("Welcome to Me"); }); module.exports = me;

You are not quite properly passing through the Router objects. Keep in mind that this is what you are trying to do:

app.use('/api', express.Router());

but what you are effectively doing right now is this:

app.use('/api', function(){ express.Router() });

So you instead of exporting a function, you should be exporting the Router itself.

manager.js

var express = require('express'); var manager = express.Router(); manager.use('/me',require('../routes/me')); module.exports = manager;

me.js

var express = require('express'); var me = express.Router(); me.route('/').get(function(req,res){ res.send("Welcome to Me"); }); module.exports = me;
