HTTP BASIC SERVER端

var http = require('http');
 
var server = http.createServer(function(req, res) {
// console.log(req); // debug dump the request
 
// If they pass in a basic auth credential it'll be in a header called "Authorization" (note NodeJS lowercases the names of headers in its request object)
 
var auth = req.headers['authorization']; // auth is in base64(username:password) so we need to decode the base64
console.log("Authorization Header is: ", auth);
 
if(!auth) { // No Authorization header was passed in so it's the first time the browser hit us
 
// Sending a 401 will require authentication, we need to send the 'WWW-Authenticate' to tell them the sort of authentication to use
// Basic auth is quite literally the easiest and least secure, it simply gives back base64( username + ":" + password ) from the browser
res.statusCode = 401;
res.setHeader('WWW-Authenticate', 'Basic realm="Secure Area"');
 
res.end('<html><body>Need some creds son</body></html>');
}
 
else if(auth) { // The Authorization was passed in so now we validate it
 
var tmp = auth.split(' '); // Split on a space, the original auth looks like "Basic Y2hhcmxlczoxMjM0NQ==" and we need the 2nd part
 
var buf = new Buffer(tmp[1], 'base64'); // create a buffer and tell it the data coming in is base64
var plain_auth = buf.toString(); // read it back out as a string
 
console.log("Decoded Authorization ", plain_auth);
 
// At this point plain_auth = "username:password"
 
var creds = plain_auth.split(':'); // split on a ':'
var username = creds[0];
var password = creds[1];
 
if((username == 'hack') && (password == 'thegibson')) { // Is the username/password correct?
 
res.statusCode = 200; // OK
res.end('<html><body>Congratulations you just hax0rd teh Gibson!</body></html>');
}
else {
res.statusCode = 401; // Force them to retry authentication
res.setHeader('WWW-Authenticate', 'Basic realm="Secure Area"');
 
// res.statusCode = 403; // or alternatively just reject them altogether with a 403 Forbidden
 
res.end('<html><body>You shall not pass</body></html>');
}
}
});
 
 
server.listen(5000, function() { console.log("Server Listening on http://localhost:5000/"); });
