控制台显示Uncaught SecurityError

Question

我不确定如何解决以下错误。有人可以帮助我吗？

Uncaught SecurityError: Failed to read the 'contentDocument' property from 'HTMLIFrameElement': Blocked a frame with origin "http://mysite.net" from accessing a frame with origin "https://www.youtube.com". The frame requesting access has a protocol of "http", the frame being accessed has a protocol of "https". Protocols must match.

Answer 1

您正在尝试从http网站中访问https网址。 HTTPS和HTTP是不同的协议，导致不匹配。

我认为以下链接可能有所帮助： https://productforums.google.com/forum/#!topic/chrome/ODpydGiCgiE

if you want to access frames in a iframe you can change top with 
parent.frames only for accessing frames in the iframe who execute javascript.
try to change top with parent.frames

return top.frames;

return parent.frames;

in google chrome it work for me i can access all my frames in my iframe.

或者，如果您只是尝试使用不同的协议访问自己的域，也可以尝试设置Access-Control-Allow-Origin标头。

How does Access-Control-Allow-Origin header work?

Answer 2

尝试使用//而不是在iFrame URL地址源地址中使用http：//或https：//指定协议。它应该使用网站的协议。
