java - 设置socket opt failed bad file number异常

Question

我在 Android 中获取设置套接字选项失败异常。我做错了什么？

    setsockopt failed: EBADF (Bad file number)

对于下面的代码:

int timeout = 500;



Socket socket = new Socket(InetAddress.getByAddress(new byte[]{10, 0, 2, 2}),
                            Integer.parseInt(m.destPort));
                    ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream());
                    oos.writeObject(m);
                    oos.close();
                    socket.setSoTimeout(timeOut);
                    ObjectInputStream iis = new ObjectInputStream(socket.getInputStream());
                    iis.readObject();
                    iis.close();
                    socket.close();

Answer 1

关闭套接字的输入或输出流会关闭其他流和套接字。

改变

oos.close();

到

oos.flush();

(Android 中的编码很糟糕。它应该抛出一个 SocketException: socket closed.)
