Nodejs Express 4路由Questin

Question

I am trying to prepend a NodeJS request through express to include /api/v1. If I make an addition like to to my server.js file:

app.all('/Employees', require('./routes/Employees'));

I am able to go forward to localhost/Employees and get the proper response (it comes back from the javascript I have written in ./routes/Employees)

If I add /api/v1/ to the beginning of the app.all call, like so:

app.all('/api/*', requireAuthentication);

I am not able to go forward to localhost/api/v1/Employees. The express manual even has an explicit note about this:

Another example is white-listed "global" functionality. The example is much like before, however it only restricts paths that start with "/api":

http://expressjs.com/api.html#app.all

Any help would be greatly appreciated.

Answer 1

Your app gets confused whenever request is received at /api/* -- it doesn't know where to go and what to do now.

If you want to prefix /api/v1 for your requests, you can do it with couple of ways - Choose what best suits your in your case:

Mountpath way -

var express = require('express'),
app = express(),
api = express();

api.all('/employees', function(req, res){
    console.log("url :: " + api.mountpath);
    res.send('hit at employess');
});

//you can do this here fo v(n)
app.use('/api/v1', api);

app.listen(3000);

other way -

var express = require('express');
var app = express();

app.all('/employees', function(req, res){
    res.send('/employe');
});
app.use('/api/v1', function(req, res, next){
    res.redirect(req.path);
});

app.listen(3000);
