If you don’t wanna install PHP to do this, why did you tag with php? You need to use a Server Side Script like Proxy PHP file, that reads the content and executes it correctly.
Proxy.php
:
<?php
header("Content-type: application/json");
die(file_get_contents($_GET["url"]));
?>
And call it like this:
url: "proxy.php?url=http://gov.uk/blah/blah"
