我用 Node.js 建了一个 tcpserver，然后用 Java 的 socket 去连接，结果 Java 这边可以把信息完整无误的发给 Node.js 这边，但是 Node.js 返回的数据始终读不到

private void initConnection() {

    if (!isRun)
        return;

    try {
        Log.i(TAG, "连接中……");
        socketClient = new Socket(_ip, _port);
        int timeout = 10000;
        socketClient.setSoTimeout(timeout);// 设置阻塞时间
        Log.i(TAG, "连接成功");
        bufferedReader = new BufferedReader(new InputStreamReader(
                socketClient.getInputStream()));

        printWriter = new PrintWriter(new BufferedWriter(new OutputStreamWriter(
                socketClient.getOutputStream())), true);



        Log.i(TAG, "输入输出流获取成功");
    } catch (UnknownHostException e) {
        Log.i(TAG, "连接错误UnknownHostException 重新获取");
        e.printStackTrace();
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e1) {
            e1.printStackTrace();
        }
        initConnection();

    } catch (IOException e) {
        Log.i(TAG, "连接服务器io错误");
        e.printStackTrace();
    } catch (Exception e) {
        Log.i(TAG, "连接服务器错误Exception" + e.getMessage());
        e.printStackTrace();
    }
}

读取部分

while (isRun) { try { if (socketClient != null) { if (bufferedReader == null) { return; } while ((line = bufferedReader.readLine()) != null) { System.out.println(line); }

            } else {
                initConnection();
            }
        } catch (Exception e) {
            Log.i(TAG, "数据接收错误" + e.getMessage());
            if (!(e instanceof SocketTimeoutException)) {
                initConnection();
            }
        }
    }
