Servlet接收的OutputStream为空

Question

这个简单的post方法没有向服务器（servlet）发送任何内容。我可以，但我不能发帖！

@Override
        protected String doInBackground(String... params) {
            try {
                URL url = new URL("http://ipaddr:8080/work/wh");
                HttpURLConnection client = (HttpURLConnection) url.openConnection();
                client.setRequestMethod("POST");
                client.setDoOutput(true);
                client.setChunkedStreamingMode(0);
                client.connect();

                OutputStream outputStream = client.getOutputStream();
                PrintWriter pw = new PrintWriter(outputStream);
                pw.println(System.currentTimeMillis());
                pw.println(System.currentTimeMillis());
                pw.println(new Float(5.6));
                pw.println(new Integer(3));
                pw.println(new Integer(2));
                pw.println(new Integer(32));
                pw.println(new Integer(2));
                pw.close();
                outputStream.close();

            }catch(Exception e){
                Log.e("text", "ux " + e.getMessage());
            }
            return null;
        }

在服务器端如果我试图读取任何行new Scanner(request.getInputStream()).nextLine();我得到

  

NoSuchElementException：找不到行

您认为可能是什么问题？

在关闭之前尝试刷新PrintWritter / Outputstream。
