javascript - 无法在'DOMWindow'上执行'postMessage'：https：//www.youtube.com！== http：// localhost：9000(Failed to execute 'postMessage' on 'DOMWindow': https://www.youtube.com !== http://localhost:9000)

Question

This is the error message that I get:

(这是我得到的错误消息：)

Failed to execute 'postMessage' on 'DOMWindow': The target origin provided
('https://www.youtube.com') does not match the recipient window's origin 
('http://localhost:9000').

I've seen other similar problems where the target origin is http://www.youtube.com and the recipient origin is https://www.youtube.com , but none like mine where the target is https://www.youtube.com and the origin is http://localhost:9000 .

(我已经看到其他类似的问题，目标来源是http://www.youtube.com ，收件人来源是https://www.youtube.com ，但没有一个像我的目标是https://www.youtube.com和原点是http://localhost:9000 。)

1. I don't get the problem.

   (我没有遇到问题。)

   What is the problem?

   (问题是什么？)

2. How can I fix it?

   (我该如何解决？)
