工具类:
using System; namespace CommonUtils { public static class ClientIpUtil { public static string GetClientIpMvc() { string userIP = "127.0.0.1"; try { if (System.Web.HttpContext.Current == null || System.Web.HttpContext.Current.Request == null || System.Web.HttpContext.Current.Request.ServerVariables == null) { return ""; } string CustomerIP = ""; //CDN加速后取到的IP simone 090805 CustomerIP = System.Web.HttpContext.Current.Request.Headers["Cdn-Src-Ip"]; if (!string.IsNullOrEmpty(CustomerIP)) { return CustomerIP; } CustomerIP = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; if (!String.IsNullOrEmpty(CustomerIP)) { return CustomerIP; } if (System.Web.HttpContext.Current.Request.ServerVariables["HTTP_VIA"] != null) { CustomerIP = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; if (CustomerIP == null) { CustomerIP = System.Web.HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]; } } else { CustomerIP = System.Web.HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]; } if (string.Compare(CustomerIP, "unknown", true) == 0 || String.IsNullOrEmpty(CustomerIP)) { return System.Web.HttpContext.Current.Request.UserHostAddress; } if (!CustomerIP.Contains(".")) CustomerIP = "127.0.0.1"; return CustomerIP; } catch { } return userIP; } } }
使用:
string ip = ClientIpUtil.GetClientIpMvc();
