buffr's Issues

how to use buffr library in node-http-proxy to copy the request and after proxying it?

Hello!
I just found this library and I would like to ask you how to use it for the node-http-proxy....
Can you help me?
Thank you!!!!

var http = require('http'),
httpProxy = require('http-proxy'),
proxy = httpProxy.createProxyServer({});  
var miTarget='web:CountryName';
var inicio = '<'+miTarget+'>';
var fin = '</'+miTarget+'>';
var buffr = require('buffr');

var server = http.createServer(function(req, res) {
var miTag = '';
var buf = req.pipe(buffr());   // Here, using buffr library I should copy the req as I understand....

req.on('data', function (data) {
// here I recover the parameter I need...
 miTag=data.toString().split(inicio)[1].split(fin)[0];

});

 req.on('end', function () {
 console.log('miTag:'+miTag);
  // After I got the parameter I want to proxy to a server depending on the parameter's value....
  if(miTag=='Portugal') {
   proxy.web(req, res, {target: 'http://www.webservicex.net'});
  }
    else {
    proxy.web(req, res, {target: 'http://other/host'}); 
  }
    });     
});

console.log("listening on port 80")
server.listen(80);

Is it possible to add a parameter (tag) to the buffer before to be sent?

Dear Jarrett,

I really appreciate your great support!

Look, I would like to modify the data before to be sent to the target. Let's suppose that I need to add a new field in the data: <extra_field>100</extra_field>

Should I do it using the buffer?

Here goes my code:

var http = require('http'),
httpProxy = require('http-proxy'),
proxy = httpProxy.createProxyServer({});
var miTarget='web:CountryName';
var inicio = '<'+miTarget+'>';
var fin = '</'+miTarget+'>';
var buffr = require('buffr');

var server = http.createServer(function(req, res) {
var miTag = '';
var buf = req.pipe(buffr()); // Here, using buffr library I should copy the req as I understand....
buf.extra_field='100' // should I add the new parameter here?

req.on('data', function (data) {
// here I recover the parameter I need...
miTag=data.toString().split(inicio)[1].split(fin)[0];

});

req.on('end', function () {
console.log('miTag:'+miTag);
// After I got the parameter I want to proxy to a server depending on the parameter's value....
if(miTag=='Portugal') {
proxy.web(req, res, {target: 'http://www.webservicex.net',buffer:buf});
}
else {
proxy.web(req, res, {target: 'http://other/host',buffer:buf});
}
});
});

console.log("listening on port 80")
server.listen(80);
