其實就是使用了百度的IP庫的功能接口,然后處理下就行了,效果圖如下:
准備工作:
1.注冊成為開度開發者,創建應用獲得百度API調用的AK秘鑰,百度開發中心地址:http://developer.baidu.com/
2.API 地址: http://developer.baidu.com/map/index.php?title=webapi/ip-api#.E4.BD.BF.E7.94.A8.E6.96.B9.E6.B3.95
3.准備開發咯,步驟如下:
(1)獲取客戶端IP
/// <summary>獲取客戶端IP地址(無視代理)</summary> /// <returns>若失敗則返回回送地址</returns> public static string GetHostAddress() { string userHostAddress = HttpContext.Current.Request.UserHostAddress; if (string.IsNullOrEmpty(userHostAddress)) { userHostAddress = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]; } //最后判斷獲取是否成功,並檢查IP地址的格式(檢查其格式非常重要) if (!string.IsNullOrEmpty(userHostAddress) && IsIP(userHostAddress)) { return userHostAddress; } return "127.0.0.1"; } /// <summary> /// 檢查IP地址格式 /// </summary> /// <param name="ip"></param> /// <returns></returns> public static bool IsIP(string ip) { return System.Text.RegularExpressions.Regex.IsMatch(ip, @"^((2[0-4]\d|25[0-5]|[01]?\d\d?)\.){3}(2[0-4]\d|25[0-5]|[01]?\d\d?)$");
(2)獲取編碼服務地址
private const string THE_KEY = "***************"; //你的AK密鑰 /// <summary>返回UTF-8編碼服務地址</summary> /// <returns>服務地址</returns> public string GetPostUrl(string theIP) { string postUrl = "http://api.map.baidu.com/location/ip?ak=" + THE_KEY + "&ip=" + theIP + "&coor=bd09ll"; return postUrl; }
(3)通過服務地址,得到地址解析結果
/// <summary> 返回結果(地址解析的結果) </summary> public static string GetInfoByUrl(string url) { //調用時只需要把拼成的URL傳給該函數即可。判斷返回值即可 string strRet = null; if (url == null || url.Trim().ToString() == "") { return strRet; } string targeturl = url.Trim().ToString(); try { HttpWebRequest hr = (HttpWebRequest)WebRequest.Create(targeturl); hr.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"; hr.Method = "GET"; hr.Timeout = 30 * 60 * 1000; WebResponse hs = hr.GetResponse(); Stream sr = hs.GetResponseStream(); StreamReader ser = new StreamReader(sr, Encoding.Default); strRet = ser.ReadToEnd(); } catch (Exception ex) { strRet = null; } return strRet; }
(4)最后簡單的調用上面的方法,然后轉換下字符串中的轉義字符
string theIP = YMethod.GetHostAddress(); string msg = YMethod.GetInfoByUrl(GetPostUrl(theIP)); msg = System.Text.RegularExpressions.Regex.Unescape(msg); Response.Write(msg);
