Using Firefox
I am trying to download some data from Google Drive
using XMLHttpRequest
. In the debug console it gives me [302 Moved Temporarily]
and the data i receive is empty. How can i get XMLHttpRequest
to follow a redirect response? Also I am using https if it changes things.
Basiclly you get the Location using xhr.getResponseHeader("Location")
. In this case you could just send another XMLHttpRequest
to this location using the same parameter:
function ajax(url /* ,params */, callback) {
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
// return if not ready state 4
if (this.readyState !== 4) {
return;
}
// check for redirect
if (this.status === 302 /* or may any other redirect? */) {
var location = this.getResponseHeader("Location");
return ajax.call(this, location /*params*/, callback);
}
// return data
var data = JSON.parse(this.responseText);
callback(data);
};
xmlhttp.open("GET", url, true);
xmlhttp.send();
}
