Getting header information inside JavaScript

问题

Is there a way to get the HTTP header information of the current page in JavaScript? I am trying to get the header information of a page like referer and other headers. How can I get those values in a JavaScript function so that I can send that information to a Java applet? The problem while I am making an Ajax call and getting header information is the referer will change to current page than the original referer.

回答1:

Use document.referrer for referrer. Use Ajax to get the rest.

function getHeadersAjax(url) {
   var r = GetXmlHttpObject();
   r.open('HEAD', url, false);
   r.send(null);
   return {
      status: r.status, 
      statusText: r.statusText, 
      referrer: document.referrer,
      rawheaders: r.getAllResponseHeaders()
   };
}

回答2:

You can use \

document.location.href

It will return the header response
