在统一 3D 上获取 JSON 响应 c# 的选定值

Question

我是 JSON 新手，我需要从 JSON 响应中获取选定的值。这是我下面的代码，请帮助我使用 narrativa covid19 api

https://api.covid19tracking.narrativa.com/api/2020-03-22/country/:countryname "

var client = new RestClient("https://api.covid19tracking.narrativa.com/api/2020-03-22/country/" + "us");
            client.Timeout = -1;
            var request = new RestRequest(Method.GET);
            IRestResponse response = client.Execute(request);
            Debug.Log(response.Content);
            string jsonStringDet = responseCountries.Content;
             Rootobject myDeserializedClass = JsonConvert.DeserializeObject<Rootobject>(jsonStringDet);

Answer 1

1. 您应该正确创建代表您的响应的类，为此，我会推荐这个站点来帮助解决这个问题：（ https://json2csharp.com/ ）
2. 您没有正确使用 RestSharp，您可以使用接受模型的通用版本Execute来解析发送的 json

var client = new RestClient("https://api.covid19tracking.narrativa.com/api/2020-03-22/country/" + "us");
client.Timeout = -1;
var request = new RestRequest(Method.GET);
var response = client.Execute<Rootobject>(request)?.Data;
            

要访问您的 Dates 对象，您只需要这样做，

var dates  = response?.dates
