https和http 调用过程当中请求头 referrer 获取不到的问题

HTTP协议规定：

    
    
    
    
    

     
     
     
     
     

    
    
    
    
    
Clients SHOULD NOT include a Referer header field in a (non-secure) HTTP request if the referring page was transferred with a secure protocol.

解决办法：

一、表单添加一个字段 referrer ，若是头部没有Referer，则获取表单的这个字段，

     添加js：

     
     
     
     
     

      
      
      
      
      

      
      
      
      
      

      
      
      
      
      

      
      
      
      
      

      
      
      
      
      

     
     
     
     
     
<input id="referrer" type="hidden" name="referrer" /> <script type="text/javascript"> document.getElementById("referrer").value = window.location.href </script>

二、后台：

     
     
     
     
     

      
      
      
      
      

      
      
      
      
      

      
      
      
      
      

      
      
      
      
      

      
      
      
      
      
 }
      
      
      
      
      

      
      
      
      
      

      
      
      
      
      

      
      
      
      
      

     
     
     
     
     
 string urlReferrer = ""; if (Request.UrlReferrer == null) { urlReferrer = Request["referrer"]; else { urlReferrer = Request.UrlReferrer.AbsoluteUri; }
