NodeJs HTTP proxy basic auth - node.js

Question

I am trying to implement a simple HTTP proxy that will only try to perform basic auth on the target host.
So far I have the following:
var http = require('http');
const my_proxy = http.createServer(function(request, response) {
console.log(request.connection.remoteAddress + ": " + request.method + " " + request.url);
const options = {
port: 80
, host: request.headers['host']
, method: request.method
, path: request.url
, headers: request.headers
, auth : 'real_user:real_password'
}
};
var proxy_request = http.request(options);
proxy_request.on('response', function (proxy_response) {
proxy_response.on('data', function(chunk) {
response.write(chunk, 'binary');
});
proxy_response.on('end', function() {
response.end();
});
response.writeHead(proxy_response.statusCode, proxy_response.headers);
});
request.on('data', function(chunk) {
proxy_request.write(chunk, 'binary');
});
request.on('end', function() {
proxy_request.end();
});
});
my_proxy.listen(8080);
However, "auth : 'real_user:real_password'" doesn't seem to do anything. Also have tried:
...
auth: {
user: real_user,
pass: real_pass
}
...

Answer 1

You have to generate the auth header
var username = 'Test';
var password = '123';
var auth = 'Basic ' + new Buffer(username + ':' + password).toString('base64');
// auth is: 'Basic VGVzdDoxMjM='
var header = {'Host': 'www.example.com', 'Authorization': auth};
var request = client.request('GET', '/', header);

Answer 2

DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the
var username = 'Test';
var password = '123';
// Deprecated
// var auth = 'Basic ' + new Buffer(username + ':' + password).toString('base64');
var auth = 'Basic ' + Buffer.from(username + ':' + password).toString('base64');
// auth is: 'Basic VGVzdDoxMjM='
var header = {'Host': 'www.example.com', 'Authorization': auth};
var request = client.request('GET', '/', header);
