.Net后台获取客户端信息
1.获取浏览器版本号
1 /// <summary> 2 /// 获取浏览器版本号 3 /// </summary> 4 /// <returns></returns> 5 public static string GetBrowser() 6 { 7 HttpBrowserCapabilities bc = HttpContext.Current.Request.Browser; 8 return bc.Browser + bc.Version; 9 }
2.获取操作系统版本号
1 /// <summary> 2 /// 获取操作系统版本号 3 /// </summary> 4 /// <returns></returns> 5 public static string GetOSVersion() 6 { 7 //UserAgent 8 var userAgent = HttpContext.Current.Request.ServerVariables["HTTP_USER_AGENT"]; 9 10 var osVersion = "未知"; 11 12 if (userAgent.Contains("NT 6.1")) 13 { 14 osVersion = "Windows 7"; 15 } 16 else if (userAgent.Contains("NT 6.0")) 17 { 18 osVersion = "Windows Vista/Server 2008"; 19 } 20 else if (userAgent.Contains("NT 5.2")) 21 { 22 osVersion = "Windows Server 2003"; 23 } 24 else if (userAgent.Contains("NT 5.1")) 25 { 26 osVersion = "Windows XP"; 27 } 28 else if (userAgent.Contains("NT 5")) 29 { 30 osVersion = "Windows 2000"; 31 } 32 else if (userAgent.Contains("NT 4")) 33 { 34 osVersion = "Windows NT4"; 35 } 36 else if (userAgent.Contains("Me")) 37 { 38 osVersion = "Windows Me"; 39 } 40 else if (userAgent.Contains("98")) 41 { 42 osVersion = "Windows 98"; 43 } 44 else if (userAgent.Contains("95")) 45 { 46 osVersion = "Windows 95"; 47 } 48 else if (userAgent.Contains("Mac")) 49 { 50 osVersion = "Mac"; 51 } 52 else if (userAgent.Contains("Unix")) 53 { 54 osVersion = "UNIX"; 55 } 56 else if (userAgent.Contains("Linux")) 57 { 58 osVersion = "Linux"; 59 } 60 else if (userAgent.Contains("SunOS")) 61 { 62 osVersion = "SunOS"; 63 } 64 return osVersion; 65 }
3.获取客户端IP地址
1 /// <summary> 2 /// 获取客户端IP地址 3 /// </summary> 4 /// <returns></returns> 5 public static string GetIP() 6 { 7 string result = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; 8 if (string.IsNullOrEmpty(result)) 9 { 10 result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]; 11 } 12 if (string.IsNullOrEmpty(result)) 13 { 14 result = HttpContext.Current.Request.UserHostAddress; 15 } 16 if (string.IsNullOrEmpty(result)) 17 { 18 return "0.0.0.0"; 19 } 20 return result; 21 }
4.取客户端真实IP
1 /// <summary> 2 /// 取得客户端真实IP。如果有代理则取第一个非内网地址 3 /// </summary> 4 public static string GetIPAddress 5 { 6 get 7 { 8 var result = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; 9 if (!string.IsNullOrEmpty(result)) 10 { 11 //可能有代理 12 if (result.IndexOf(".") == -1) //没有“.”肯定是非IPv4格式 13 result = null; 14 else 15 { 16 if (result.IndexOf(",") != -1) 17 { 18 //有“,”，估计多个代理。取第一个不是内网的IP。 19 result = result.Replace(" ", "").Replace("'", ""); 20 string[] temparyip = result.Split(",;".ToCharArray()); 21 for (int i = 0; i < temparyip.Length; i++) 22 { 23 if (IsIPAddress(temparyip[i]) 24 && temparyip[i].Substring(0, 3) != "10." 25 && temparyip[i].Substring(0, 7) != "192.168" 26 && temparyip[i].Substring(0, 7) != "172.16.") 27 { 28 return temparyip[i]; //找到不是内网的地址 29 } 30 } 31 } 32 else if (IsIPAddress(result)) //代理即是IP格式 33 return result; 34 else 35 result = null; //代理中的内容 非IP，取IP 36 } 37 38 } 39 40 string IpAddress = (HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null && HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != String.Empty) ? HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] : HttpContext.Current.Request.ServerVariables["HTTP_X_REAL_IP"]; 41 42 if (string.IsNullOrEmpty(result)) 43 result = HttpContext.Current.Request.ServerVariables["HTTP_X_REAL_IP"]; 44 45 if (string.IsNullOrEmpty(result)) 46 result = HttpContext.Current.Request.UserHostAddress; 47 48 return result; 49 } 50 }
5.判断是否是IP格式
1 /// <summary> 2 /// 判断是否是IP地址格式 0.0.0.0 3 /// </summary> 4 /// <param name="str1">待判断的IP地址</param> 5 /// <returns>true or false</returns> 6 public static bool IsIPAddress(string str1) 7 { 8 if (string.IsNullOrEmpty(str1) || str1.Length < 7 || str1.Length > 15) return false; 9 10 const string regFormat = @"^d{1,3}[.]d{1,3}[.]d{1,3}[.]d{1,3}$"; 11 12 var regex = new Regex(regFormat, RegexOptions.IgnoreCase); 13 return regex.IsMatch(str1); 14 }
6.获取公网IP
1 /// <summary> 2 /// 获取公网IP 3 /// </summary> 4 /// <returns></returns> 5 public static string GetNetIP() 6 { 7 string tempIP = ""; 8 try 9 { 10 System.Net.WebRequest wr = System.Net.WebRequest.Create("http://city.ip138.com/ip2city.asp"); 11 System.IO.Stream s = wr.GetResponse().GetResponseStream(); 12 System.IO.StreamReader sr = new System.IO.StreamReader(s, System.Text.Encoding.GetEncoding("gb2312")); 13 string all = sr.ReadToEnd(); //读取网站的数据 14 15 int start = all.IndexOf("[") + 1; 16 int end = all.IndexOf("]", start); 17 tempIP = all.Substring(start, end - start); 18 sr.Close(); 19 s.Close(); 20 } 21 catch 22 { 23 if (System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName()).AddressList.Length > 1) 24 tempIP = System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName()).AddressList[1].ToString(); 25 if (string.IsNullOrEmpty(tempIP)) 26 return GetIP(); 27 } 28 return tempIP; 29 }
