学习使用API

学习使用获取天气信息API和获取地理编码API制作一个简易天气信息获取器（高德API）

首先建立一个用来获取返回相关信息的类OpenWeatherMapProxy。

由于我选择返回数据类型为Json，所以我先把返回的Json利用Json2Csharp.com自动生成相关信息的属性。然后两个方法

GetAdcode和GetWeather来回去返回信息中adcode和weatherinfo。
public class OpenWeatherProxy
    {
        public static async Task<RootObject> GetAdcode(string s)
        {
            var http = new HttpClient();
            var response = await http.GetAsync("http://restapi.amap.com/v3/geocode/geo?address="+s+"&key=自己的开发ID&output=json");
            var result = await response.Content.ReadAsStringAsync();
            var serializer = new DataContractJsonSerializer(typeof(RootObject));

            var ms = new MemoryStream(Encoding.UTF8.GetBytes(result));
            var data =http://www.mamicode.com/ (RootObject)serializer.ReadObject(ms);

            return data;
        }
        public static async Task<RootObject> GetWeather(string s)
        {
            var http = new HttpClient();
            var response = await http.GetAsync("http://restapi.amap.com/v3/weather/weatherInfo?key=自己的开发ID&city=" + s + "&extension=base&output=json");
            var result = await response.Content.ReadAsStringAsync();
            var serializer = new DataContractJsonSerializer(typeof(RootObject));

            var ms = new MemoryStream(Encoding.UTF8.GetBytes(result));
            var data =http://www.mamicode.com/ (RootObject)serializer.ReadObject(ms);

            return data;
        }
