将 Json 字符串发布到 Web Api Windows Store 8.1

Question

由于 webClient 已弃用且 SharpRest 不适用于 Windows 8.1，我需要将我的 json 字符串传递给 web api。

字符串 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();}

现在这里的 baseaddress 是一个带有 url 地址的字符串。但即使我将 IsSuccessStatusCode 设为 true，也没有输入 json。
我应该在这个 link
中看到输入的结果 Android 团队正在发布他们的参数值在哪里

usersJSON=[{"userName":"jerin","userId":"3"}]

根据@Jon 的回答，我编辑了我的代码，而不是 os System.Net.Http 我现在使用的是 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();
