During the development process, we encountered such a need to display products in different regions according to the user's geographical location.

WeChat is used here: the function of obtaining the user's geographical location (reported every 5 seconds or when entering a reply), we convert it into an actual address based on the longitude and latitude pushed by WeChat, which is used here It is Baidu Map API (if you want to use it, apply for Baidu ak first).

PS: This function of WeChat is very unstable, it is unreliable, and it often does not push. . . (Manual positioning was added later, and the Baidu Map Web positioning component is pretty good, not an advertisement! 0.0)

BaiduGeoCoding is an object encapsulated for the corresponding results of the Api:

public class BaiDuGeoCoding
    {
        public int Status { get; set; }
        public Result Result { get; set; }
    }

    public class Result

        public string Formatted_Address { get; set; }

        public string Business { get; set; }

        public AddressComponent AddressComponent { get; set; }

        public string CityCode { get; set; }
    }

    public class AddressComponent

    }

    public class Location

Call:

            //需配置 WeiXineConst的BaiduAk
            string lat = "31.1430"; //經(jīng)度
            string lng = "121.2943";// 緯度
            var model = WeiXinHelper.GeoCoder(lat, lng);
