问题描述

http协议系统之间交互，出现的编程的报错。我该怎样修改？求大神啊

现在我们系统跟gps之间交互，我采用的httpClient，可是每次跑程序的时候都会报错

 java.net.SocketException: Software caused connection abort: recv failed
    at java.net.SocketInputStream.socketRead0(Native Method)
    at java.net.SocketInputStream.read(Unknown Source)
    at org.apache.http.impl.io.SessionInputBufferImpl.streamRead(SessionInputBufferImpl.java:139)
    at org.apache.http.impl.io.SessionInputBufferImpl.fillBuffer(SessionInputBufferImpl.java:155)
    at org.apache.http.impl.io.SessionInputBufferImpl.readLine(SessionInputBufferImpl.java:284)
    at org.apache.http.impl.conn.DefaultHttpResponseParser.parseHead(DefaultHttpResponseParser.java:140)

我的实现的代码

 public String sendMessage(String xmlMessage)throws Exception{

         // 创建默认的httpClient实例.
               CloseableHttpClient httpclient = HttpClients.createDefault();
               // 创建httppost
                HttpPost httppost = new HttpPost("http://192.168.46.35:8080/BGpsWeb/gpsForeignInterface/shipLocation.do");  

         String responseMessage=null;
        List<NameValuePair> formparams = new ArrayList<NameValuePair>();
        //formparams.add(new BasicNameValuePair("cqdd", xmlMessage));
        formparams.add(new BasicNameValuePair("cqdd", xmlMessage));
        UrlEncodedFormEntity entity;

        try {
            entity = new UrlEncodedFormEntity(formparams, "GBK");
            httppost.setEntity(entity);
            System.out.println("executing request " + httppost.getURI());
            CloseableHttpResponse response = httpclient.execute(httppost);
            try {
                HttpEntity reEntity = response.getEntity();
               if (entity != null) {
                    System.out.println("--------------------------------------");
                    responseMessage=EntityUtils.toString(reEntity);
                   //System.out.println("Response content: " + EntityUtils.toString(reEntity, "UTF-8"));
                    System.out.println("--------------------------------------");
                }
            } finally {
                response.close();
                }
            } catch (ClientProtocolException e) {
                e.printStackTrace();
            } catch (UnsupportedEncodingException e1) {
                e1.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            } finally {
                // 关闭连接,释放资源
                try {
                  httpclient.close();
               } catch (IOException e) {
                    e.printStackTrace();
                }
            }  

        return responseMessage;

    }

解决方案

1.用本机电脑ping一下你要连接的地址是可用的嘛？

2.需要长连接嘛？你那个错误，貌似是连接问题，有可能是网络不稳定造成的。

解决方案二：

是不是你读取数据的时候异常了。服务器返回的数据你处理正确吗
