Question

从我的Android应用程序中，我需要调用一个Web服务来检索一些数据。为了调用该Web服务，我使用HttpPost实体。

问题是我收到了这个错误：

此行的错误在以下方法中：

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;
}

该方法是从AsyncTask调用的。

任何人都知道我做错了什么？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。

Answer 1

只是关闭连接的服务器。

摘自this question

这非常致命。远程服务器向您发送了一个RST数据包，表明连接立即丢失，而不是通常的握手。这绕过了正常的半闭状态转换。我喜欢这个描述：


“通过对等方重置连接”是TCP / IP等同于将电话重新关闭。它更礼貌而不仅仅是不回复，留下一个悬挂。但这并不是真正礼貌的TCP / IP逆转所期望的FIN-ACK。

DefaultHttpClient android的java.net.SocketException
