Getting HTTP headers with Node.js

Question

Is there a built in way to get the headers of a specific address via node.js?

something like,

var headers = getUrlHeaders("http://stackoverflow.com"); 

would return

HTTP/1.1 200 OK. Cache-Control: public, max-age=60. Content-Type: text/html; charset=utf-8. Content-Encoding: gzip. Expires: Sat, 07 May 2011 17:32:38 GMT. Last-Modified: Sat, 07 May 2011 17:31:38 GMT. Vary: *. Date: Sat, 07 May 2011 17:31:37 GMT. Content-Length: 32516. 

Answer 1

This sample code should work:

var http = require('http'); var options = {method: 'HEAD', host: 'stackoverflow.com', port: 80, path: '/'}; var req = http.request(options, function(res) {     console.log(JSON.stringify(res.headers));   } ); req.end(); 

Answer 2

Try to look at http.get and response headers.

var http = require("http");  var options = {   host: 'stackoverflow.com',   port: 80,   path: '/' };  http.get(options, function(res) {   console.log("Got response: " + res.statusCode);    for(var item in res.headers) {     console.log(item + ": " + res.headers[item]);   } }).on('error', function(e) {   console.log("Got error: " + e.message); });
