iframe与外部页面不起作用 [英] iframe with external page not working

问题描述

我正努力在iframe中嵌入一个网页，但它根本不起作用。具有相对路径的内部页面正常显示。但这个简单的代码不起作用：

 < iframe src =http://www.google.com/ >< / iframe中> 
  

应该显示iframe的地方只是空的。

这怎么可能？

解决方案

Google使用X-FRAME-OPTIONS HTTP标头禁止将页面放入iframe：
https://developer.mozilla.org/zh/The_X-FRAME-OPTIONS_response_header

几乎所有的现代浏览器都会拒绝将这个HTTP头的页面放在iframe中。没有什么可以做的。

I'm tring to embed a webpage in an iframe, but it doesn't work at all. internal pages with relative path are displayed normally. but this simple code doesn't work:

<iframe src="http://www.google.com/"></iframe>

the place that supposed to show the iframe is just empty. i looked in the page source and there is nothing after

How can this be?

解决方案

Google uses an X-FRAME-OPTIONS HTTP header to disallow putting their pages in iframes: https://developer.mozilla.org/en/The_X-FRAME-OPTIONS_response_header

Almost all modern browsers will refuse to put pages with this HTTP header in an iframe. There's nothing you can do about that.
