我一直在尋找一些時(shí)間來解決這個問題。我正在嘗試將 Weather Unlocked 本地天氣 API ( https://developer.weatherunlocked.com/documentation/localweather ) 添加到我的網(wǎng)站。但是我只能返回所有當(dāng)前值。我希望能夠取出特定的項(xiàng)目，例如溫度、濕度或緯度/經(jīng)度，而不會出現(xiàn)其他所有內(nèi)容。代碼 const string WEBSERVICE_URL = "http://api.weatherunlocked.com/api/current/51.50,-0.12?app_id=42fd0793&app_key=cd2365f533caad77dc2d874aabc1625b"; try { var webRequest = WebRequest.Create(WEBSERVICE_URL); if (webRequest != null) { webRequest.Method = "GET"; webRequest.ContentType = "application/json"; webRequest.Headers["X-API-Key"] = "cd2365f533caad77dc2d874aabc1625b"; //Get the response WebResponse wr = webRequest.GetResponseAsync().Result; Stream receiveStream = wr.GetResponseStream(); StreamReader reader = new StreamReader(receiveStream); string content = reader.ReadToEnd(); lblContent.Text = content; } } catch (Exception ex) { lblContent.Text = ex.ToString(); }結(jié)果{ "lat":51.5, "lon":0.05, "alt_m":5.0, "alt_ft":16.4, "wx_desc":"Clear skies", "wx_code":0, "wx_icon":"Clear.gif", "temp_c":7.0, "temp_f":44.6, "feelslike_c":2.6, "feelslike_f":36.68, "humid_pct":70.0, "windspd_mph":19.26, "windspd_kmh":31.0, "windspd_kts":16.74, "windspd_ms":8.61, "winddir_deg":250.0, "winddir_compass":"WSW", "cloudtotal_pct":25.0, "vis_km":10.0, "vis_mi":6.21, "vis_desc":null, "slp_mb":1002.0, "slp_in":29.67, "dewpoint_c":1.93, "dewpoint_f":35.47}顯然，這很混亂，并非一切都是必要的。提前致謝！編輯 我嘗試反序列化，但出現(xiàn)以下錯誤：System.NullReferenceException: Object reference not set to an instance of an object當(dāng)我在反序列化中編寫 foreach 循環(huán)時(shí)，我得到了這個。我的猜測是它正在調(diào)用“天氣”類型的對象（類似于給定示例中對象 facebookFriend 的類型為 Facebook），并且沒有任何內(nèi)容存儲在天氣對象中。也許我在 API 的調(diào)用中做錯了什么，我應(yīng)該將它存儲在我的 Weather 類中？

我在手機(jī)上輸入了這個，但是是這樣的：
using System;
using System.Net;
using Newtonsoft.Json;
public class Program
{
public static void Main()
{
string json = new WebClient().DownloadString("** YOUR URL **");
WeatherData weatherData = JsonConvert.DeserializeObject<WeatherData>(json);
Console.WriteLine("Lat: " + weatherData.Lat);
Console.WriteLine("Lon: " + weatherData.Lon);
Console.WriteLine("Alt_M: " + weatherData.Alt_M);
Console.WriteLine("Alt_FT: " + weatherData.Alt_FT);
Console.WriteLine("WX_Desc: " + weatherData.WX_Desc);
Console.WriteLine("WX_Code: " + weatherData.WX_Code);
Console.WriteLine("WX_Icon: " + weatherData.WX_Icon);
Console.WriteLine("Temp_C: " + weatherData.Temp_C);
Console.WriteLine("Temp_F: " + weatherData.Temp_F);
Console.WriteLine("Feelslike_C: " + weatherData.Feelslike_C);
Console.WriteLine("Feelslike_F: " + weatherData.Feelslike_F);
Console.WriteLine("Humid_PCT: " + weatherData.Humid_PCT);
Console.WriteLine("Windspd_MPH: " + weatherData.Windspd_MPH);
Console.WriteLine("Windspd_KMH: " + weatherData.Windspd_KMH);
Console.WriteLine("Windspd_KTS: " + weatherData.Windspd_KTS);
Console.WriteLine("Windspd_MS: " + weatherData.Windspd_MS);
Console.WriteLine("Winddir_DEG: " + weatherData.Winddir_DEG);
Console.WriteLine("Winddir_Compass: " + weatherData.Winddir_Compass);
Console.WriteLine("Cloudtotal_PCT: " + weatherData.Cloudtotal_PCT);
Console.WriteLine("Vis_KM: " + weatherData.Vis_KM);
Console.WriteLine("Vis_MI: " + weatherData.Vis_MI);
Console.WriteLine("Vis_Desc: " + weatherData.Vis_Desc);
Console.WriteLine("\n");
