Hi there, I have tried your method but chrome responds with Access to XMLHttpRequest at 'xxx' from origin 'xx' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Please let me know how to solve it. Thanks!
BTW The url I am using starts with https, if that is the case.
