代理IP分享asp.net如何获得浏览器IP地址

asp.net如何获得浏览器的IP使用地址?想要实现这一操作,其实有两种方式可以完成,代理IP下面分别为大家介绍并且附上详细的操作代码一览。

 

代理IP分享asp.net如何获得浏览器IP地址

 

1、通过后台代码实现

 

#region IP地址限制功能 2017-07-18

/// <summary>

///

/// </summary>

/// <returns></returns>

public bool IsIPValidate()

{

bool flag = false;

string userip = GetLoginIp();

string[] addr = GetAddressByIp(userip);

string addrs = addr[0] + addr[1];

if (“北京”.Equals(addr[0]) || “北京”.Equals(addr[1]))

{

flag = true;

}

return flag;

}

/// <summary>

/// 获取远程访问用户的Ip地址

/// </summary>

/// <returns>返回Ip地址</returns>

protected string GetLoginIp()

{

string loginip = “”;

//Request.ServerVariables[“”]–获取服务变量集合

if (Request.ServerVariables[“REMOTE_ADDR”] != null) //判断发出请求的远程主机的ip地址是否为空

{

//获取发出请求的远程主机的Ip地址

loginip = Request.ServerVariables[“REMOTE_ADDR”].ToString();

}

//判断登记用户是否使用设置代理

else if (Request.ServerVariables[“HTTP_VIA”] != null)

{

if (Request.ServerVariables[“HTTP_X_FORWARDED_FOR”] != null)

{

//获取代理的服务器Ip地址

loginip = Request.ServerVariables[“HTTP_X_FORWARDED_FOR”].ToString();

}

else

{

//获取客户端IP

loginip = Request.UserHostAddress;

}

}

else

{

//获取客户端IP

loginip = Request.UserHostAddress;

}

return loginip;

}

/// <summary>

/// 根据IP获取省市

/// </summary>

public string[] GetAddressByIp(string ip)

{

string PostUrl = “http://int.dpool.sina.com.cn/iplookup/iplookup.php?ip=” + ip;

string res = GetDataByPost(PostUrl);//该条请求返回的数据为:res=1t115.193.210.0t115.194.201.255t中国t浙江t杭州t电信

string[] arr = getAreaInfoList(res);

return arr;

}

/// <summary>

/// Post请求数据

/// </summary>

/// <param name=”url”></param>

/// <returns></returns>

public string GetDataByPost(string url)

{

HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);

string s = “anything”;

byte[] requestBytes = System.Text.Encoding.ASCII.GetBytes(s);

req.Method = “POST”;

req.ContentType = “application/x-www-form-urlencoded”;

req.ContentLength = requestBytes.Length;

Stream requestStream = req.GetRequestStream();

requestStream.Write(requestBytes, 0, requestBytes.Length);

requestStream.Close();

HttpWebResponse res = (HttpWebResponse)req.GetResponse();

StreamReader sr = new StreamReader(res.GetResponseStream(), System.Text.Encoding.Default);

string backstr = sr.ReadToEnd();

sr.Close();

res.Close();

return backstr;

}

/// <summary>

/// 处理所要的数据

/// </summary>

/// <param name=”ip”></param>

/// <returns></returns>

public static string[] getAreaInfoList(string ipData)

{

//1t115.193.210.0t115.194.201.255t中国t浙江t杭州t电信

string[] areaArr = new string[10];

string[] newAreaArr = new string[2];

try

{

//取所要的数据,这里只取省市

areaArr = ipData.Split(‘t’);

newAreaArr[0] = areaArr[4];//省

newAreaArr[1] = areaArr[5];//市

}

catch (Exception e)

{

}

return newAreaArr;

}

#endregion

 

2、js方法

 

<!DOCTYPE html>

<html>

<head>

<meta charset=”UTF-8″ />

<title>Document</title>

<script src=”http://pv.sohu.com/cityjson?ie=utf-8″></script>

<script type=”text/javascript”>

document.write(‘IP地址:’ + returnCitySN[“cip”] + ‘, 城市编码:’ + returnCitySN[“cid”] + ‘, 地区:’ + returnCitySN[“cname”]);

</script>

</head>

<body>

</body>

</html>

 

通过上面2种方式,客户端浏览器的IP地址就可以获取到了。迅联加速拥有多年动态拨号服务器运营经验,自有资源搭建动态IP服务器,轻松上手!
