c# - 仅在Safari浏览器中，ASP.net MVC中IFrame中的 session 为空

页面包含IFrame，并且仅在Safari中， session 为null。我的Safari版本是5.1.7

我正在使用MVC 4.5一切都可以在其他浏览器中完美运行。我正在使用以下代码。

protected override void OnResultExecuting(ResultExecutingContext filterContext)
{
     base.OnResultExecuting(filterContext);
     filterContext.HttpContext.Response.AddHeader("p3p", "CP=\"CAO PSA OUR\"");
     GetFirstError();
}

最佳答案

我们有和完全相同的问题-FB应用程序在ASP.Net MVC项目中的Safari中不起作用。这是我们为修复它所做的事情:

将P3P header 添加到所有 repo 中。您可以在IIS服务器级别上对其进行配置:http://support.microsoft.com/kb/324013-或直接在global.asax中进行配置:

protected void Application_BeginRequest(Object sender, EventArgs e)
{
      HttpContext.Current.Response.AddHeader("P3P", "CP=\"NOI CURa ADMa DEVa TAIa OUR BUS IND UNI COM NAV INT\"");
}

根据此Microsoft指南在网站的根目录(所谓的知名位置)中创建w3c文件夹，并将p3p.xml和policy.p3p文件上载到该文件夹​​:

这是我的p3p.xml文件:

<META>
  <POLICY-REFERENCES>
    <POLICY-REF about="/w3c/policy.p3p">
      <INCLUDE>/</INCLUDE>
      <COOKIE-INCLUDE/>
    </POLICY-REF>
  </POLICY-REFERENCES>
</META>

和policy.p3p(抱歉，它很长，但是我不确定如何将其隐藏为破坏者):
