1. HTML
<iframe src="https://cn.bing.com/" width="100%" height="500px"> </iframe>2. 请求URL显示错误： Refused to display 'http://127.0.0.1:8000/show/' in a frame because it set 'X-Frame-Options' to 'sameorigin'.
X-Frame-Options：https://developer.mozilla.org/zh-CN/docs/Web/HTTP/X-Frame-Options
Django中的X-Frame-Options设置：https://developer.mozilla.org/zh-CN/docs/Web/HTTP/X-Frame-Options
3. 设置iframe的高度根据网页的高度变化
<script type="application/javascript"> function resizeIFrameToFitContent( iFrame ) { // iFrame.width = document.body.scrollWidth; iFrame.height = window.screen.height - 300; } window.addEventListener('DOMContentLoaded', function(e) { // var iFrame = document.getElementsByTagName( 'iframe' ); // resizeIFrameToFitContent( iFrame ); // or, to resize all iframes: var iframes = document.querySelectorAll("iframe"); for( var i = 0; i < iframes.length; i++) { resizeIFrameToFitContent( iframes[i] ); } } ); </script>
