Android端和后台.NET通讯json连接异常，希望大家指点

Android端代码：

public class HttpUtil {
 public static final String BASE_URL = "http://192.168.31.146:23062/";
 }
public ProductDetail queryproductsproductsId(int productsId)
 {
 String path = HttpUtil.BASE_URL+"ToysRent/Product/ProductDetail?Id="+productsId+"";
 URL url;
 try {
 url = new URL(path);
 HttpURLConnection conn = (HttpURLConnection) url.openConnection();
 conn.setReadTimeout(5000);
 conn.setRequestMethod("POST");
 [color=#FF0000] if (200 == conn.getResponseCode())[/color]
 {
 //获取输入流
InputStream is = conn.getInputStream(); 
 ToolsHandler toolsHandler=new ToolsHandler(); 
 byte[] data=toolsHandler.InputStreamToByte(is);
 json=new String(data);
 System.out.println(json);
 product =getGson().fromJson(json, new TypeToken() {}.getType());
 }
 } catch (Exception e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 }
  return product;
 }

.NET后台代码：

    [HttpPost]
    public ActionResult ProductDetail(int id)
    {
        Products product=_productService.GetModel(id);
        // 向客户端输出返回信息json数据
        if (product != null) {

            JsonResult jsr = Json(product);
            return jsr;
        } else {
            return Json("error");
        }
    }
