NodeJS加密的HTTPS响应主体

Question

I'm creating a small icloud client using node, so that I can pull down some of my data and analyze it. I'm currently scripting the login sequence. When I receive a response the headers are fine, and the session cookies i expect are there, but the response body which should be JSON looks encrypted, it's not even plain text. It's over SSL, but if the headers are readable, shouldn't the body be as well? Is there a setting I'm missing or a bug in node, i'm using the latest, 0.8.1

According to the response header content-encoding: gzip , the response isn't encrypted, it's just compressed. You can use Node's zlib module to decompress it on the fly. Here's an example using my blog's homepage as the endpoint (since my server responds with gzipped data when asked):

http = require('http');
zlib = require('zlib');
url = require('url');

var uri = url.parse("http://brandontilley.com/");
uri.headers = {'accept-encoding': 'gzip'};

var request = http.get(uri, function(res) {
  var buffers = [];
  res.pipe(zlib.createGunzip()).on('data', function(chunk) {
    buffers.push(chunk);
  }).on('end', function() {
    console.log(Buffer.concat(buffers).toString());
  });
});
request.end();

There are some more examples on the Node.js documentation for the zlib module .
