如何在节点+ Express应用中设置路由以通过身份验证方法？

Question

I'm following the auth0 backend set up tutorial, and I'm wondering how I can set up my routes in a separate file instead of in app.js .

In the tutorial, they create

var authenticate = jwt({
  secret: new Buffer(process.env.AUTH0_CLIENT_SECRET, 'base64'),
  audience: process.env.AUTH0_CLIENT_ID
});

and then app.use('/secured', authenticate);

If I want to set up my routes in some routes folder routes/index.js , and I want to use this authenticate() , how can I set that up in my app.js ?

I know I have to do something like var routes = require('./routes/index.js'); , but how do I set up the app.use( .. ) in this case so it uses authenticate() ?

Thanks

Answer 1

You can define a routes module in ./routes/index.js like this:

// ./routes/index.js

module.exports = function (app) {
   app.get('/secured', getSecuredController);
};

function getSecuredController (req, res) {
   res.send('/secured OK');
}

And in your main app.js file:

// ./app.js

var initializeRoutes = require('./routes');
var authenticate = jwt({..});

app.use('/secured', authenticate);
initializeRoutes(app);

You can return router from file routes/index.js:

// routes/index.js

const express = require('express');

module.exports = function(options) {
    const router = express.Router();

    router.get('/', (req, res, next) => {
        // process route...
    });

    // define other routes...

    return router;
};

And the use it in server:

// server.js

const express = require('express');
const router = require('./routes/index.js');

const authenticate = jwt({
  secret: new Buffer(process.env.AUTH0_CLIENT_SECRET, 'base64'),
  audience: process.env.AUTH0_CLIENT_ID
});

var app = express()

app.use('/secured', authenticate, router());

This will make your router configurable and reusable.
