大虾们这个问题怎么解决:java.net.SocketException: Connection reset(急!!!在线等)

Question

_socket = new Socket (host, port);
            System.out.println(new BufferedReader(new InputStreamReader(_socket.getInputStream())).readLine());
就最后一句出错了

Answer 1

是对方关闭了连接，看看socket server的代码如何实现的

Answer 3

上面是我的代码,帮我看看.不知道为什么readLine老是出错

Answer 4

你是Server是怎么接的?
这个看不出有什么问题.
听听楼下的看法

Answer 5

不好意思，写错。
按字节来取。不要取行，因为如果readline的话，必定要求对方发送的数据中带有\r或者\n
