其实就是使用了百度的ip库的功能接口,然后处理下就行了,效果图如下:
[flash=500,400]http://s1.knowsky.com/20160211/wyxfazu4vve12.png[/flash]
准备工作:
1.注册成为开度开发者,创建应用获得百度API调用的AK秘钥,百度开发中心地址: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.准备开发咯,步骤如下:
(1)获取客户端IP
///<summary>获取客户端IP地址(无视代理)</summary>///<returns>若失败则返回回送地址</returns>publicstaticstringGetHostAddress()
{stringuserHostAddress =HttpContext.Current.Request.UserHostAddress;if(string.IsNullOrEmpty(userHostAddress))
{
userHostAddress= HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
}//最后判断获取是否成功,并检查IP地址的格式(检查其格式非常重要)if(!string.IsNullOrEmpty(userHostAddress) &&IsIP(userHostAddress))
{returnuserHostAddress;
}return"127.0.0.1";
}///<summary>///检查IP地址格式///</summary>///<param name="ip"></param>///<returns></returns>publicstaticboolIsIP(stringip)
{returnSystem.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)获取编码服务地址
privateconststringTHE_KEY ="***************";//你的AK密钥///<summary>返回UTF-8编码服务地址</summary>///<returns>服务地址</returns>publicstringGetPostUrl(stringtheIP)
{stringpostUrl ="http://api.map.baidu.com/location/ip?ak="+ THE_KEY +"&ip="+ theIP +"&coor=bd09ll";returnpostUrl;
}
(3)通过服务地址,得到地址解析结果
///<summary>返回结果(地址解析的结果)</summary>publicstaticstringGetInfoByUrl(stringurl)
{//调用时只需要把拼成的URL传给该函数即可。判断返回值即可stringstrRet =null;if(url ==null|| url.Trim().ToString() =="")
{returnstrRet;
}stringtargeturl =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=newStreamReader(sr, Encoding.Default);
strRet=ser.ReadToEnd();
}catch(Exception ex)
{
strRet=null;
}returnstrRet;
}
(4)最后简单的调用上面的方法,然后转换下字符串中的转义字符
stringtheIP =YMethod.GetHostAddress();stringmsg =YMethod.GetInfoByUrl(GetPostUrl(theIP));
msg=System.Text.RegularExpressions.Regex.Unescape(msg);
Response.Write(msg);
