Whois with JavaScript | 易学教程

问题

I want to be able to get whois data (and idn domains too) by client-side javascript. Is it possible? Maybe some free REST-like WhoIs service exists?

回答1:

Try using http://whoisxmlapi.com service.

The service URL: http://www.whoisxmlapi.com/whoisserver/WhoisService

You need to specify outputFormat=json and domainName=insert_domain_here parameters..

Example URL: http://www.whoisxmlapi.com/whoisserver/WhoisService?outputFormat=json&domainName=stackoverflow.com.

Example code (using jQuery to simplify AJAX communication):

$.ajax({
  url: 'http://www.whoisxmlapi.com/whoisserver/WhoisService',
  dataType: 'jsonp',
  data: {
    domainName: 'stackoverflow.com',
    outputFormat: 'json'
  },
  success: function(data) {
    console.log(data.WhoisRecord);
  }
});

HERE is the working code.

Update:

The service mentioned above is not free, but there are several free whois services that are providing HTML output and by using YQL you can retrieve the HTML as a JS. See THIS answer for more details.

Example (using jQuery & jquery.xdomainajax):

var domain = 'stackoverflow.com';
$.ajax({
  url: 'http://whois.webhosting.info/' + domain,
  type: 'GET',
  success: function(res) {
    // using jQuery to find table with class "body_text" and appending it to a page
    $(res.responseText).find('table.body_text').appendTo('body');
  }
});

HERE is the working code.

You need to have a look at the structure of the HTML document and select, process and display the data you are interested in. The example is just printing whole table without any processing.

What you can do if you have exec() enabled in php is create a php file with the following:

exec('whois domain.com');

and then create aa .ajax() request to the php script where you pass the domain name and output it.

i'm also trying to find out a free whois provider with JSON output, couldn't find one. But, there are WHOIS windows client provided by Microsoft and like someone mentioned above, we can use PHP/cgi to get the details.

I'm not sure whether there's any WHOIS lookup/query provider gives JSON output at free cost.

BTW, i just found this phpWhois from sourceforge.net, would be a good starting point to use whois from the server. This is the library used by RoboWhois / RubyWhois provider as well.

An npm package called node-whois did the job for me. It's server side JS, not client side, but perhaps this will help someone.
