I came across this issue when running a wordpress web site. I tried all sorts of things to fix it and wasn't sure how, ultimately the issue was because I was using DNS forwarding with masking, and the links to external sites were not being addressed properly. i.e. my site was hosted at http://123.456.789/index.html but was masked to run at http://somewebSite.com/index.html. When i entered http://123.456.789/index.html in the browser clicking on those same links resulted in no X-frame-origins issues in the JS console, but running http://somewebSite.com/index.html did. In order to properly mask you must add your host's DNS name servers to your domain service, i.e. godaddy.com should have name servers of example, ns1.digitalocean.com, ns2.digitalocean.com, ns3.digitalocean.com, if you were using digitalocean.com as your hosting service.

更新2019:您可以使用客户端JavaScript和我的X-Frame-Bypass Web组件绕过<iframe>中的X-Frame-Options。下面是一个演示:x帧旁路中的黑客新闻。(在Chrome和Firefox中测试。)

如果你在YouTube视频中遇到这个错误，不要使用完整的url，而是使用共享选项中的嵌入url。它看起来像http://www.youtube.com/embed/eCfDxZxTBW4

您还可以更换手表吗?v= with embed/ so http://www.youtube.com/watch?v=eCfDxZxTBW4变成http://www.youtube.com/embed/eCfDxZxTBW4

使用下面给出的这一行，而不是header()函数。

echo "<script>window.top.location = 'https://apps.facebook.com/yourappnamespace/';</script>";

虽然没有提及，但在某些情况下可以有所帮助:

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
    if (xhr.readyState !== 4) return;
    if (xhr.status === 200) {
        var doc = iframe.contentWindow.document;
        doc.open();
        doc.write(xhr.responseText);
        doc.close();
    }
}
xhr.open('GET', url, true);
xhr.send(null);
