一、墨迹接口调用

private String host =ConfigurationManager.AppSettings["WeatherHost"];//接口直接写到webconfig中        private const String pathWeather = "/whapi/json/alicityweather/briefforecast3days";        private const String method = "POST";        private String appcode = ConfigurationManager.AppSettings["WeatherAppCode"];//你的appcode,        private const String pathAQI = "/whapi/json/alicityweather/briefaqi";        private string GetWeatherORAQI(string path, int cityId = 2)        {            String querys = "";            String bodys = "cityId=" + cityId;            String url = host + path;            HttpWebRequest httpRequest = null;            HttpWebResponse httpResponse = null;            if (0 < querys.Length)            {                url = url + "?" + querys;            }            if (host.Contains("https://"))            {                ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult);                httpRequest = (HttpWebRequest)WebRequest.CreateDefault(new Uri(url));            }            else            {                httpRequest = (HttpWebRequest)WebRequest.Create(url);            }            httpRequest.Method = method;            httpRequest.Headers.Add("Authorization", "APPCODE " + appcode);            //根据API的要求，定义相对应的Content-Type            httpRequest.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";            if (0 < bodys.Length)            {                byte[] data = Encoding.UTF8.GetBytes(bodys);                using (Stream stream = httpRequest.GetRequestStream())                {                    stream.Write(data, 0, data.Length);                }            }            try            {                httpResponse = (HttpWebResponse)httpRequest.GetResponse();            }            catch (WebException ex)            {                httpResponse = (HttpWebResponse)ex.Response;            }            //Console.WriteLine(httpResponse.StatusCode);            //Console.WriteLine(httpResponse.Method);            //Console.WriteLine(httpResponse.Headers);            Stream st = httpResponse.GetResponseStream();            StreamReader reader = new StreamReader(st, Encoding.GetEncoding("utf-8"));            return reader.ReadToEnd();        }        public static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)        {            return true;        }

二、这里接口调用可以直接在墨迹实例中找到，返回数据格式为JSON格式，下面进行返回天气数据处理。

var json = GetWeatherORAQI(pathWeather); //接口调用，返回JSON数据var WeatherJson = JsonConvert.DeserializeObject
     
      (json);//数据反序列化                List
      
        models = new List
       
        ();                 //循环获取未来三天天气，保存到集合中                foreach (var item in WeatherJson.data.forecast)                {
                        WeatherModel mode = new WeatherModel();                    mode.city = WeatherJson.data.city.pname;                    mode.date = item.predictDate;                    mode.weather = item.conditionDay;                    mode.temperature = string.Format("{0}-{1}", item.tempDay, item.tempNight);                    mode.wind = Enum.GetName(typeof(WindEnum), Convert.ToInt32(item.windLevelDay.Split('-')[0]));                    mode.airQuality = GetAQI(int.Parse(AQIModel.data.aqi.value));                    mode.dress = item.windLevelDay.Split('-')[0];                    mode.curtemperature = item.tempDay;                    models.Add(mode);                }                 //未来三天天气，进行序列化保存到数据库中                var weather = JsonConvert.SerializeObject(models);                WeatherInfo winfo = new WeatherInfo()                {                    Date = DateTime.Now.Date,                    CityCode = 2,                    Weather = weather                };                _context.WeatherInfo.Add(winfo);                _context.SaveChanges();
       
      
     

三、天气需要每天获取最新，这里可用定时任务完成，每天早晨8点进行更新

public MyJobs()        {            Schedule(() =>            {                IServices.IWeatherService _service = new WeatherService();                _service.Save();            }).ToRunEvery(1).Days().At(8, 0);        }
