I'm having issues trying to retrieve a JSON list from Flickr using plain JavaScript and XMLHttpRequest. Here is an example of an AJAX call without a callback function that is not functioning properly:
var url = "https://api.flickr.com/services/feeds/photos_public.gne?tags=rat&format=json&nojsoncallback=1";
xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
console.log(xhr.status);
console.log(xhr.readyState);
if (xhr.readyState == 4 && xhr.status == 200) {
var data = JSON.parse(xhr.responseText);
console.log(data);
}else {
console.log("error");
}
}
xhr.open("GET", url)
xhr.send();The error message I'm encountering is -
js:1 Access to XMLHttpRequest at 'https://api.flickr.com/services/feeds/photos_public.gne?tags=rat&format=json&nojsoncallback=1' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.Can anyone help me identify where the issue lies?
