使用node.js获取HTTP标头 [英] Getting HTTP headers with node.js

问题描述

是否存在通过node.js获取特定地址的标头的内置方法?

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

类似

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

会返回

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.

推荐答案

此示例代码应该有效:

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();
