NodeJS HTTP Post - GZip

node.js

Solution

To send a compressed request, compress the data into a `zlib` buffer, then write that as your output:

var zlib = require('zlib');
var options = {
  hostname: 'www.example.com',
  port: 80,
  path: '/upload',
  method: 'POST',
  headers: {'Content-Encoding': 'gzip'} // signal server that the data is compressed
};
zlib.gzip('my data\ndata\n', function (err, buffer) {
    var req = http.request(options, function(res) {
        res.setEncoding('utf8');// note: not requesting or handling compressed response
        res.on('data', function (chunk) {
            // ... do stuff with returned data
        });
    });
    req.on('error', function(e) {
        console.log('problem with request: ' + e.message);
    });

    req.write(buffer); // send compressed data
    req.end();
});

That should send a gzipped request to the server and get a non-compressed response back. See the other answers to this question for handling a compressed response.

Problem

I have a NodeJS client that is similar to ``` var options = { hostname: 'www.google.com', port: 80, path: '/upload', method: 'POST' }; var req = http.request(options, function(res) { console.log('STATUS: ' + res.statusCode); console.log('HEADERS: ' + JSON.stringify(res.headers)); res.setEncoding('utf8'); res.on('data', function (chunk) { console.log('BODY: ' + chunk); }); }); req.on('error', function(e) { console.log('problem with request: ' + e.message); }); // write data to request body req.write('data\n'); req.write('data\n'); req.end(); ``` Is there any way to make the data element in the req.write gzipped at all?
