Question

我从asyntask中的json检索一些数据，然后转到另一个页面而不在json中完成检索数据。发生套接字异常（警告）。这是日志猫。

如何解决此警告？

编辑：

       protected String doInBackground(String... arg0) {
     if (isCancelled()){
         cancel(true);
         return "";
      }else{
    try {
        postParameters.add(new BasicNameValuePair("keyCode",Encode.getKeyCode()));
        postParameters.add(new BasicNameValuePair("version",Encode.getVersion()));
        string response = vv.executeHttpPost(vv.common_URL()+"abc.php",postParameters);


    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
      }
}

Answer 1

在重新连接另一个请求之前，您需要使用响应正文。您不仅应该读取响应状态，而且应该完全读取响应InputStream到最后一个字节，从而忽略读取的字节。
