iFrame blocked due to portocols, domains & ports must match

问题:

I am getting the error below:

Blocked a frame with origin https://<my host ip> from accessing a frame with origin https://<target host ip>. Protocols, domains, and ports must match.

If you notice both are 'https'. But still the error occurs. Please help - how do I avoid this.

回答1:

As the title says:

 domains & ports must match 

Two different ips, that means you have two different domains.

Read about the same origin policy

If you control both domains, you need to look into window.postMessage

回答2:

Protocols, domains, and ports must match

<my host ip> is not the same as <target host ip> These are both parts of the domain in the url.

http:// is the Protocol
ip or website name is the domain
:xxxx is the port

so end result: http://ip:xxxx
