从我的 android 应用程序中，我需要调用 Web 服务来检索一些数据。为了调用该 Web 服务，我使用了一个HttpPost实体。

问题是我收到此错误：

错误在此行的以下方法中：

response = client.execute(post);


public boolean sendJsonauthRegisterSession(JSONObject json, String url) {

    HttpParams httpParameters = new BasicHttpParams();
    int timeoutConnection = 150000;
    HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection); 
    int timeoutSocket = 150000;
    HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
    DefaultHttpClient client = new DefaultHttpClient(httpParameters);

    HttpResponse response;
    try {
        HttpPost post = new HttpPost(url);
        JSONObject js = new JSONObject();
        js.put("request_object", json);

        StringEntity se = new StringEntity(js.toString());
        se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE,
                "application/json"));
        post.setEntity(se);
        response = client.execute(post);

        /* Checking response */
        if (response != null) {
                    ...
        }
     } 
      catch(UnknownHostException e5){
          e5.printStackTrace();           
          this.callRegister="register_failed";
     } 
      catch(SocketException ex) {
          ex.printStackTrace();
          this.callRegister="register_failed";
     } 
      catch (Exception e) {
          e.printStackTrace();
          this.callRegister="register_failed";
     }

    client.getConnectionManager().shutdown();
    return registersession;
}

从 调用该方法AsyncTask。

有人知道我做错了什么吗？谢谢！！！

重要与服务器的连接是在 3G、EDGE 上完成的......所以它非常慢。

只是切断连接的服务器。

从这个问题中提取

这是相当致命的。远程服务器向您发送了一个 RST 数据包，这表明连接立即断开，而不是通常的握手。这绕过了正常的半关闭状态转换。我喜欢这样的描述：

“由对等方重置连接”是 TCP/IP 等价物，相当于将电话重新挂上。这比仅仅不回复，留下一个悬而未决更有礼貌。但这并不是真正礼貌的 TCP/IP 话务员所期望的 FIN-ACK。
