Question

我正在使用DefaultHttpClient对apache服务器执行post请求。我想得到回应。当响应像100符号工作正常时，当我有300个符号的biger响应时，我有套接字执行：套接字关闭。

例外：

我的代码：

DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);
        HttpResponse getResponse= null;



        if(json_post!=null){
            StringEntity se=null;
            try {
                se = new StringEntity(json_post.toString());
            } catch (UnsupportedEncodingException e3) {
                // TODO Auto-generated catch block
                e3.printStackTrace();
            }
            //sets the post request as the resulting string
            httpPost.setEntity(se);
        }
        HttpProtocolParams.setUserAgent(httpClient.getParams(), "Mozilla/5.0");try {
            getResponse = httpClient.execute(httpPost);

        } catch (ClientProtocolException e2) {
            statusCode = "ClientProtocolException";
            e2.printStackTrace();
        } catch (IOException e2) {
            statusCode = "IOException";
            e2.printStackTrace();
        } finally {
            httpClient.getConnectionManager().shutdown(); // Close the instance here
        }



        if (getResponse == null) return null;
        statusCode = ""+getResponse.getStatusLine().getStatusCode();
        if (!statusCode.equals( ""+HttpStatus.SC_OK) ) { 
           Log.w(getClass().getSimpleName(), 
              "Error " + statusCode + " for URL " + url); 

           return null;
        }


        HttpEntity getResponseEntity = getResponse.getEntity();

        InputStream inputStream = null;
        try {
            inputStream = getResponseEntity.getContent();
        } catch (IllegalStateException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }

        ByteArrayOutputStream content = new ByteArrayOutputStream();

        // Read response into a buffered stream
        int readBytes = 0;
        byte[] sBuffer = new byte[512];
        try {
            while ((readBytes = inputStream.read(sBuffer)) != -1) {
                content.write(sBuffer, 0, readBytes);
            }
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }

        // Return result from buffered stream
        String dataAsString = new String(content.toByteArray());

请帮助：）

问题：我终于“关机”连接，没有这条线工作完美！

finally {
   httpClient.getConnectionManager().shutdown(); // Close the instance 
}

android SocketException：Socket关闭
