Question

Trying to download a page in a popup code but it returns status of zero.

console.log("Req");
var req = new XMLHttpRequest();
req.open(
    "GET",
    "http://www.google.com",
    true);
req.onload = function() {
  console.log("DONE!!!");
  console.log(req.responseText);
}
req.send(null);

I did set this in my manifest:

"permissions": [
   "http://www.google.com"
]

Whats wrong? Why the response is zero?

Answer 1

Google.com is not the best page for testing. I bet when you open it in a browser it redirects you to your localized google page (it redirects me to http://www.google.ca for example). So you would need to add that redirected url to the permissions as well.

Another problem is that your permission domain does not end with /:

"permissions": [
   "http://www.google.com/",  "http://www.google.ca/"
]
