将Json字符串发布到Web Api Windows应用商店8.1

Question

由于不推荐使用webClient而且SharpRest不适用于Windows 8.1,我需要将我的json字符串传递给web api.

string js = @"[{""userName"":""jerin"",""userId"":""a""}]";

var baseAddress ="http://epub3.in/sample/android%20webservice/webservice/insertuser.php/";

        HttpClient httpClient = new HttpClient();
         HttpClient httpClient = new HttpClient();
        httpClient.BaseAddress = new Uri(baseAddress);
        httpClient.DefaultRequestHeaders.Accept.Clear();
        httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        try
        {
            HttpResponseMessage response =  httpClient.PostAsync("",
                new StringContent(
                    js,
                    Encoding.UTF8,
                    "application/json")).Result;
              string sd = response.IsSuccessStatusCode.ToString();}

现在这里baseaddress是一个包含url地址的字符串.但即使我将IsSuccessStatusCode设为true,也没有输入json.
我应该看到 Android团队在这个链接中输入的结果
是他们的参数值

usersJSON = [{ "的userName": "jerin", "用户id": "3"}]

根据@ Jon的回答,我编辑了我的代码而不是os System.Net.Http我现在正在使用Windows.Web.http,但它仍然没有上传

        Windows.Web.Http.HttpClient httpClient = new Windows.Web.Http.HttpClient();
        Windows.Web.Http.HttpRequestMessage msg = new Windows.Web.Http.HttpRequestMessage(new Windows.Web.Http.HttpMethod("POST"), new Uri(baseAddress));
        msg.Content = new HttpStringContent((js));
        msg.Content.Headers.ContentType = new HttpMediaTypeHeaderValue("application/json");
        Windows.Web.Http.HttpResponseMessage response = await httpClient.SendRequestAsync(msg).AsTask();

Answer 1

尝试使用Windows.Web.Http命名空间中的HttpClient:

            HttpClient httpClient = new HttpClient();
            HttpRequestMessage msg = new HttpRequestMessage(new HttpMethod("POST"), new Uri(baseAddress));
            msg.Content = new HttpStringContent(js);
            msg.Content.Headers.ContentType = new HttpMediaTypeHeaderValue("application/json");
            HttpResponseMessage response = await _httpClient.SendRequestAsync(msg).AsTask();
