带有自定义JsonConverter的.net HttpClient

json

我正在使用.NET的HttpClient向WebAPI发出请求,该WebAPI返回一些JSON数据,该数据需要在客户端进行一些自定义反序列化。为此,我已经完成了自己的工作JsonConverter,但是我不知道如何让该ReadAsAsync<T>方法处理转换器的存在。

通过使用ReadAsStringAsync读取响应,然后将该字符串传递给JsonConvert.DeserializeObject,我已经解决了我的问题,但是似乎应该有一个更优雅的解决方案。

这是我的代码:

public PrefsResponse GetAllPrefs(string sid) {
    HttpClient client = CreateHttpClient(null, sid);
    var response = client.GetAsync("api/sites/" + sid).Result;

    // TODO : find a way to hook custom converters to this...
    // return response.Content.ReadAsAsync<PrefsResponse>().Result;

    var stringResult = response.Content.ReadAsStringAsync().Result;

    return JsonConvert.DeserializeObject<PrefsResponse>(stringResult, new PrefClassJsonConverter());
}

这是我所能做到的最好的,还是有一些更优雅的方法?

如果需要连接,我也在这里创建HttpClient:

        private HttpClient CreateHttpClient(CommandContext ctx, string sid) {
        var cookies = new CookieContainer();

        var handler = new HttpClientHandler {
            CookieContainer = cookies,
            UseCookies = true,
            UseDefaultCredentials = false
        };

        // Add identity cookies:
        if (ctx != null && !ctx.UserExecuting.IsAnonymous) {
            string userName = String.Format("{0} ({1})", ctx.RequestingUser.UserName, ctx.UserExecuting.Key);
            cookies.Add(new Cookie(__userIdCookieName, userName));
            cookies.Add(new Cookie(__sidCookieName, sid));
            cookies.Add(new Cookie(__hashCookieName,
                                   GenerateHash(userName, Prefs.Instance.UrlPrefs.SharedSecret)));
        }

        var client = new HttpClient(handler) {
            BaseAddress = _prefServerBaseUrl
        };

        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));



        return client;
    }

您可以将JsonSerializerSettings转换器列表与一起传递给,供JsonMediaTypeFormatter以下人员使用ReadAsAsync<T>

var obj = await result.Content.ReadAsAsync<refsResponse>(
    new[] {new JsonMediaTypeFormatter {
          SerializerSettings = new JsonSerializerSettings { 
              Converters = new List<JsonConverter> {
                //list of your converters
               }
             } 
          }
    });
