在BaasBox中使用HttpClient创建文档？

Question

在这个BaasBox系列之后，我之前发布了BaasBox和C#来自WP8，以了解如何从WP8应用程序登录到BaasBox服务器。我已经做到了。

现在，在尝试创建一个新记录(在BaasBox中称为Document )时，我遇到了一个问题。请参阅这里)到特定集合中。

这是我使用的代码：

string sFirstName = this.txtFirstName.Text;
string sLastName = this.txtLasttName.Text;
string sAge = this.txtAge.Text;
string sGender = ((bool)this.rbtnMale.IsChecked) ? "Male" : "Female";

try
{
    using(var client = new HttpClient())
    {
        //Step 1: Set up the HttpClient settings
        client.BaseAddress = new Uri("http://MyServerDirecction:9000/document/MyCollectionName");
        //client.DefaultRequestHeaders.Accept.Clear();
        //client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

        //Step 2: Create the request to send
        HttpRequestMessage requestMessage = new HttpRequestMessage(HttpMethod.Post, "http://MyServerDirecction:9000/document/MyCollectionName");
        //Add custom header
        requestMessage.Headers.Add("X-BB-SESSION", tokenId);

        //Step 3: Create the content body to send
        string sContent = string.Format("fname={0}&lname={1}&age={2}&gender={3}", sFirstName, sLastName, sAge, sGender);
        HttpContent body = new StringContent(sContent);
        body.Headers.ContentType = new MediaTypeHeaderValue("application/json");
        requestMessage.Content = body;

        //Step 4: Get the response of the request we sent
        HttpResponseMessage response = await client.SendAsync(requestMessage, HttpCompletionOption.ResponseHeadersRead);

        if (response.IsSuccessStatusCode)
        {
             //Code here for success response
        }
        else
             MessageBox.Show(response.ReasonPhrase + ". " + response.RequestMessage);
   }
}
catch (Exception ex)
{
   MessageBox.Show(ex.Message);
}

在测试上面的代码时，我得到了以下异常

{Method: POST, RequestUri: 'http://MyServerDirecction:9000/document/MyCollectionName', Version: 1.1, Content: System.Net.Http.StringContent, Headers:
{
  X-BB-SESSION: e713d1ba-fcaf-4249-9460-169d1f124cbf
  Content-Type: application/json
  Content-Length: 50
}}

有人知道如何使用HttpClient向BaasBox服务器发送json数据吗？或者上面的代码有什么问题？

提前感谢！

您必须以JSON格式发送身体。根据BaasBox文档，主体有效负载必须是有效的JSON (http://www.baasbox.com/documentation/?shell#create-a-document)

尝试将sContent字符串格式化为：

//Step 3: Create the content body to send
string sContent = string.Format("{\"fname\":\"{0}\",\"lname\":\"{1}\",\"age\":\"{2}\",\"gender\":\"{3}\"}", sFirstName, sLastName, sAge, sGender);

或者可以使用JSON.NET (http://james.newtonking.com/json)或任何类似的库以简单的方式操作JSON。
