How to use request or http module to read gzip page into a string

Question

I found the request module in js cannot handle gzip or inflate format http response correctly.

for example:

request({url:\'some url\'}, function (err         


        

Answer 1

Pipe the response to the gzip stream and use it as you would use the original response object.

var req = http.request(options, function(res) {
    var body = "";

    res.on('error', function(err) {
       next(err);
    });

    var output;
    if( res.headers['content-encoding'] == 'gzip' ) {
      var gzip = zlib.createGunzip();
      res.pipe(gzip);
      output = gzip;
    } else {
      output = res;
    }

    output.on('data', function (data) {
       data = data.toString('utf-8');
       body += data;
    });

    output.on('end', function() {
        return next(false, body);
    });
 });

req.on('error', function(err) {
   next(err);
})
