无法在“DOMWindow"上执行“postMessage":提供的目标源与收件人窗口的源不匹配(“null") [英] Failed to execute 'postMessage' on 'DOMWindow': The target origin provided does not match the recipient window's origin ('null')

问题描述

我在 heroku 中有一个游戏，现在我试图让它在 Facebook 画布中运行，但是，虽然它可以在 Firefox 中运行，但在 Chrome 和 IE 中却不能.

I have a game in heroku, now I'm trying to make it work in Facebook canvas, but, while it works in Firefox, in Chrome and IE doesn't.

IE 显示带有按钮的警告，单击按钮时显示内容.

IE shows a warning with a button, when clicking the button, it shows the content.

在 chrome 中，我收到此错误:

In chrome, I get this error:

Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://game.herokuapp.com') does not match the recipient window's origin ('null').

怎么了?

推荐答案

确保您(或 Facebook)向其发布消息的目标窗口已完成加载.大多数情况下，我收到此错误的原因是我向其发送消息的 iframe 未能加载.

Make sure the target window that you (or Facebook) is posting a message to, has completed loading. Most of the times I've gotten this error were when an iframe I was sending messages to had failed to load.
