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

Question

页面包含 IFrame 且 session 仅在 Safari 的情况下为空。我的 Safari 版本是 5.1.7

我正在使用 MVC 4.5 一切都在其他浏览器中完美运行。我正在使用下面的代码..

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

Answer 1

我们有完全相同的问题 - FB 应用程序在 ASP.Net MVC 项目的 Safari 中无法运行。以下是我们为修复它所做的工作:

1. 将 P3P header 添加到所有 reposons。您可以在 IIS 服务器级别配置它:http://support.microsoft.com/kb/324013 - 或者直接在 global.asax 中执行:

   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\"");
   }
   

2. 在您网站的根目录(所谓的知名位置)创建w3c 文件夹并上传p3p.xml 和policy.p3p 按照 Microsoft 指南将文件放入其中:How to Deploy P3P Privacy Policies on Your Web Site

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，但我不确定如何隐藏它作为剧透):
