Question

已在xamarin应用程序上构建此服务：

public class OpenWeatherMap<T>
{
    private const string OpenWeatherApi = "http://api.openweathermap.org/data/2.5/weather?q=";
    private const string Key = "653b1f0bf8a08686ac505ef6f05b94c2";

    HttpClient _httpClient = new HttpClient();

    // aqui podemos enviar directo a una ciudad hardcoded
    public async Task<T> GetAllWeathers(string city)
    {
        var json = await _httpClient.GetStringAsync(OpenWeatherApi + city + "&APPID=" + Key);
        var getWeatherModels = JsonConvert.DeserializeObject<T>(json);
        return getWeatherModels;
    }
}

当我检查模型对象始终为空时。 JSON很好，我的课程与我的JSON模型完全匹配。我正在使用Newtonsoft.Json。

这是我的模特

我使用的是拉丁美洲（智利）的Visual Studio社区集，因此我尝试将JSON上的每个小数字段更改为模型上的字符串，以避免逗号分隔问题，但是无论如何，我的对象都为空我将JSON注入反序列化器。预先感谢。

在Xamarin服务上反序列化时，对象始终为空
