本文介绍了是否关闭套接字的输入流也关闭套接字连接?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
在的Java API,
In Java API,
Socket socket = serverSocket.accept();
BufferedReader fromSocket = new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintWriter toSocket = new PrintWriter(socket.getOutputStream());
//do sth with fromSocket ... and close it
fromSocket.close();
//then write to socket again
toSocket.print("is socket connection still available?\r\n");
//close socket
socket.close();
在上面的code,之后我关闭InputStream fromSocket,似乎插座连接不可用了 - 客户不会收到是socket连接仍然可用的消息。
这是否意味着关闭套接字的输入流也关闭套接字本身呢?
In the above code, after I close the InputStream fromSocket, it seems that the socket connection is not available anymore--the client wont receive the "is socket connection still available" message.Does that mean that closing the inputstream of a socket also closes the socket itself?
推荐答案
是,关闭输入流关闭套接字。您需要使用套接字的shutdownInput方法,以close刚输入流:
Yes, closing the input stream closes the socket. You need to use the shutdownInput method on socket, to close just the input stream:
//do sth with fromSocket ... and close it
socket.shutdownInput();
然后,您仍然可以发送到输出插孔
Then, you can still send to the output socket
//then write to socket again
toSocket.print("is socket connection still available?\r\n");
//close socket
socket.close();
