Android端和后台.NET通讯json连接异常，希望大家指点

Question

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;

}
配置文件：

.NET后台代码：
路径详情，红色圈出
[img=http://img.bbs.csdn.net/upload/201504/30/1430393337_919353.png][/img]

    [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");
        }
    }

debug时在Android红色出出现异常：failed to connect to /192.168.31.146 (port 23062): connect failed: ETIMEDOUT

急需大家指点呀，谢啦

Answer 1

 HttpURLConnection conn = (HttpURLConnection) url.openConnection();
 conn.connect();//加上这句,如果地址没问题的话，
