node.js - HTTP Auth with dynamic URLs in Express.JS -

i've got route in express 3.0 app defined this:

app.post('/:app/find', auth, function(req, res){ 

i'd restricted using http authorization. auth function looks this:

var auth = express.basicauth(function(user, pass, callback){     callback(null, user === 'user' && pass === 'pass'); }); 

i'd auth function database lookup based on req.params.app url, , authenticate users accordingly. problem i'm not sure how access yet, since function defined in app.post hasn't been called yet when auth run. can it? there different implementation of http auth should using?

there isn't proper way of doing express.basicauth (i looked @ other modules provide similar functionality, never seem pass req authentication function either), create middleware instantiates every request want authenticate:

var express = require('express'); var app     = express();  var basicauth = express.basicauth; var auth      = function(req, res, next) {   ...here can access 'req'...   basicauth(function(user, pass, callback) {     ...here can use variables set in block above...     callback(null, user === 'user' && pass === 'pass');   })(req, res, next); };  app.get('/', auth, function(req, res) {   res.send('authenticated!'); });  app.listen(3012);
