原标题:Trying to detect a call to my web app made by facebook

在我的笔记本中,我想要知道这是否是我的手脚(如果与我的网站连接,是作为联邦银行的一个地位共享的,而联邦银行则试图获得一些元子供开张)。 我曾尝试过LURlReferer, 它是空的,用户HostName显示是IP的添加器。

问题回答

你可以像Tejs所建议的那样做:

IPHostEntry IpEntry = Dns.GetHostByAddress(HttpContext.Current.Request.UserHostAddress); 
//OR
IPHostEntry IpEntry = Dns.GetHostByAddress(HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]);
if(IpEntry.HostName.Contains("facebook.com"))
{
  //Coming from facebook.com
}

象这样的种子:

if ((!string.IsNullOrWhiteSpace(HttpContext.Request.UserAgent) && HttpContext.Request.UserAgent.ToLower().Contains("facebookexternalhit")) ||
    ((HttpContext.Request.UrlReferrer != null) && HttpContext.Request.UrlReferrer.Host.ToLower().Contains("facebook.com")))

这样,我知道Facebook是否gra开了开张的数据,或者有人从面板网页上点击了共用链接。
