问题
here is my embed code:
<iframe src="https://www.youtube-nocookie.com/embed/x9pRNcoP1EU" frameborder="0" allowfullscreen></iframe>
here is the error in console
Access to XMLHttpRequest at 'https://googleads.g.doubleclick.net/pagead/id' from origin 'https://www.youtube-nocookie.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
I tried to add the following at the top of php page - without success
header("Access-Control-Allow-Origin: *");
how to solve this?
回答1:
As @david-vielhuber said in the comments, this isn't related to your domain but to the CORS policy on "googleads.g.doubleclick.net". There is nothing you can do beyond changing the way you embed YouTube videos.
CORS Policy Reference

add this to your .htaccess: Header set Access-Control-Allow-Origin "*"
