HttpRequest API

The HttpRequest API implements a subset of the W3C XmlHttpRequest specification, and makes it available in both workers and the main HTML page.

Contents

Overview

Since the browser's XmlHttpRequest object is not available in the context of a worker, Gears provides its own HttpRequest object to fill that need. Gears HttpRequest provides most of the features of XmlHttpRequest except for the ability to access the response as an XML DOM object and the ability to send a request synchronously.

Permission

Does not require user permission.

Example

<script type="text/javascript" src="gears_init.js"></script>
<script type="text/javascript">
var request = google.gears.factory.create('beta.httprequest');
request.open('GET', '/index.html');
request.onreadystatechange = function() {
  if (request.readyState == 4) {
    console.write(request.responseText);
  }
};
request.send();
</script>
