我如何获得用户IP和国家/地区名称 [英] How I get user IP and country name

问题描述

protected void GetIpLocation()
        {

            string ipAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
            if (string.IsNullOrEmpty(ipAddress))
            {
                ipAddress = Request.ServerVariables["REMOTE_ADDR"];
            }

            string APIKey = "e56f667f98265912bc0fa937413351933be9d3e15aeee6448b3d8443e8d47c48";
            string url = string.Format("http://api.ipinfodb.com/v3/ip-city/?key=e56f667f98265912bc0fa937413351933be9d3e15aeee6448b3d8443e8d47c48&format=json", APIKey, ipAddress);
            using (WebClient client = new WebClient())
            {
                string json = client.DownloadString(url);
                Location location = new JavaScriptSerializer().Deserialize<location>(json);
                List<location> locations = new List<location>();
                locations.Add(location);

                gvLocation.DataSource = locations; // bind data in gridview
                gvLocation.DataBind();


            }

        }

我是什么尝试过：



我已经在我的本地计算机上获取了所有数据。但是当我生活我的代码然后返回服务器IP和国家。我想要用户他使用我的网站时的数据。这是我在C＃中的代码

What I have tried:

I have already get all data on my local computer.But when I live my code then return Server IP and Country.I want User data when he use my website.This is my code in C#

推荐答案

引用：

string url = string.Format("http" + "://api.ipinfodb.com/v3/ip-city/?key=e56f667f98265912bc0fa937413351933be9d3e15aeee6448b3d8443e8d47c48&format=json", APIKey, ipAddress);

有问题 - 您的格式字符串不包含参数的任何占位符，因此您需要检索IP地址的信息发出请求的计算机。



更改字符串以包含API密钥和IP地址的占位符：

There's your problem - your format string doesn't contain any placeholders for the parameters, so your retrieving the information for the IP address of the computer making the request.

Change the string to include placeholders for the API key and IP address:

string url = string.Format("http" + "://api.ipinfodb.com/v3/ip-city/?key={0}&ip={1}&format=json", APIKey, ipAddress);

注意：我必须添加+来分解网址，以防止网站在其周围插入< a> 标记。您不需要在代码中包含它。

NB: I've had to add a " + " to break up the URL, to prevent the site from inserting <a> tags around it. You don't need to include that in your code.
