两个站点:
- a.sample.com
- b.sample.com
a.sample.com 站点中的一段示例 JS 代码:
var iframe = document.createElement("iframe");
iframe.id = "frame";
iframe.src="http://b.sample.com/index.html";
iframe.onload = function() {
var domdoc = iframe.contentDocument || iframe.contentWindow.document;
domdoc.write("Test");
alert("..or..")
domdoc.body.innerHTML = "<em>Cake</em>";
}
document.body.appendChild(iframe);
如果 b.sample.com 站点禁止被 a.sample.com 站点 iframe 框架引用,需要在 a.sample.com 站点中配置请求头 X-Frame-Options:
- DENY(禁止被任何站点引用): The page cannot be displayed in a frame, regardless of the site attempting to do so.
- SAMEORIGIN(只能被本站点引用): The page can only be displayed in a frame on the same origin as the page itself.
ASP.NET MVC 站点设置方法:
1. Html.BeginForm
@Html.AntiForgeryToken()//默认设置为 SAMEORIGIN。
2. Application_Start
protected void Application_Start()
{
AntiForgeryConfig.SuppressXFrameOptionsHeader = true;
}
3. web.config
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="X-Frame-Options" value="DENY" />
</customHeaders>
</httpProtocol>
</system.webServer>
</configuration>
4. IIS 站点设置
