使用 RestSharp 反序列化 JSON

Question

我正在使用RetSharp向http://api.weatherapi.com/v1/current.json发出请求，如下所示：

        var request = new RestSharp.Serializers.Newtonsoft.Json.RestRequest();
        request.AddHeader("content-type", "application/json");
        var client = new RestClient(URL + urlParameters);
        client.Proxy = WebRequest.DefaultWebProxy; // I was led to believe this will fix my problem of my requests taking minutes on end to execute, but it didn't that much.
        var queryResult = client.Execute(request).Content;
        var response = JsonConvert.DeserializeObject<CurrentJsonResponse>(queryResult);

这很好用，但我不喜欢我必须单独调用JsonConvert ，而且，据说 RestSharp 应该支持内置的那种东西。

我尝试了以下方法：

        var response = client.Execute<CurrentJsonResponse>(request).Data; // returns a CurrentJsonResponse object with null properties.

        request.JsonSerializer = new NewtonsoftJsonSerializer(); // I put it at the very start, but doesn't help.

        var jsonDeserializer = new JsonDeserializer();
        client.AddHandler("application/json", jsonDeserializer); // Second verse, same as the first.

        var response = client.Execute<object>(request).Data; // Correctly creates an annonymous object that has the right properties/information but it's not exactly what I'm going for. As I wanted it strongly-typed.

没有任何效果。 如何反序列化我通过 RestSharp 获得的 json 响应，而无需单独调用 Newtonsoft。 我已经下载了RestSharp.Serializers.Newtonsoft.Json nuget。

Answer 1

在你的第二次尝试中尝试改变

 var jsonDeserializer = new JsonDeserializer();
 client.AddHandler("application/json", jsonDeserializer);

至

client.AddHandler("application/json", () => new RestSharp.Serializers.Newtonsoft.Json.NewtonsoftJsonSerializer());

并调用：

var response = client.Execute<CurrentJsonResponse>(request).Data;

默认反序列化应该可以正常工作，我只需要在发布请求期间更改一些序列化设置。

   var request = new RestRequest();    
   var restClient = new RestClient(endPoint);

   request.Method = Method.GET;

   request.AddHeader("Content-Type", "application/json");

   var response = restClient.Execute<T>(request);

       if (response.ErrorException != null)
       {
            //log the exception
            //throw exception;
       }
   return response.Data;

根据我的经验，如果映射 class 不正确，我已经看到默认反序列化不会产生预期的结果。 确保您已将 JSON 响应正确转换为相应的 c# class。
