如何获得用户';用C#表示的国家名称?
我目前正在使用地理定位来获取用户的国家名称。这是我的密码:如何获得用户';用C#表示的国家名称?,c#,javascript,jquery,html,geolocation,C#,Javascript,Jquery,Html,Geolocation,我目前正在使用地理定位来获取用户的国家名称。这是我的密码: navigator.geolocation.getCurrentPosition(function (pos) { var latlng = pos.coords.latitude + "," + pos.coords.longitude; var apiurl = 'http://maps.google.com/maps/geo?output=json&sensor=false&q=' + latlng
navigator.geolocation.getCurrentPosition(function (pos) {
var latlng = pos.coords.latitude + "," + pos.coords.longitude;
var apiurl = 'http://maps.google.com/maps/geo?output=json&sensor=false&q=' + latlng;
var yqlqry = encodeURIComponent('select * from json where url="' + apiurl + '"');
var yqlurl = 'http://query.yahooapis.com/v1/public/yql?q=' + yqlqry + '&format=json&callback=?';
$.getJSON(yqlurl, function (data) {
var countryName = data.query.results.json.Placemark.AddressDetails.Country.CountryName;
var newCountryName = countryName.toLowerCase();
if (newCountryName == "united states")
newCountryName = "us";
else if (newCountryName == "england" || newCountryName == "ireland" || newCountryName == "scotland" || newCountryName == "wales" || newCountryName == "northern ireland")
newCountryName = "uk";
else if (newCountryName == "australia")
newCountryName = "au";
else if (newCountryName == "canada")
newCountryName = "ca";
else
newCountryName = "world";
$('a[title = "' + newCountryName + '"]').trigger('click');
});
});
我宁愿使用服务器端的东西。是否有人知道您是否可以在服务器端以C#?的形式获取用户的国家/地区名称,您唯一可以回复的是IP地址,您可以使用该地址执行位置查找。有免费的数据库没有IP地址到位置的映射,或者您可以使用HostIP.info
查看了解更多信息。不知道这是否有帮助,但在本地

为什么不试试IP2Location的API
你可以这样传递你的IP地址
http://api.ip2location.com/?ip=145.228.219.221&key=demo

在C#中提出相同的请求-从navigator的GeoAPI获取您的位置,并将其转发到服务器上您自己的web服务,该服务器使用
WebClient
Classic发出get请求。我想向您指出,爱尔兰不在英国。北爱尔兰是,但爱尔兰是爱尔兰共和国,本身就是一个国家。
