客户端通过套接字从服务器接收邮件时有些问题 [英] some problem when client receive messages from server though socket

问题描述

在我的服务器代码中：

pw = new PrintWriter(stream);
br = new BufferedReader(new InputStreamReader(
    socket.getInputStream(), "UTF-8"));

在我的客户端代码中

BufferedReader br = new BufferedReader(new InputStreamReader(
                    clientSocket.getInputStream(), "UTF-8"));
OutputStreamWriter stream = new OutputStreamWriter(clientSocket.getOutputStream(), "UTF-8");
PrintWriter pw = new PrintWriter(stream);

然后
，服务器使用：
pw.println（OK ）;
pw.flush（）;

then at first, server use: pw.println("OK"); pw.flush();

客户端接收OK

之后，服务器使用： / p>

After that, server use:

pw.println("TRUE")
pw.flush();

这次，客户端收到一个字符串，含有unknow char

this time, client receive a string that has unknow char

\ufffd\ufffdTRUE

然后我继续发送msg给客户端，它将在每个句子之前收到一些\\\�。

then i keep send msg to client and it will receive some \ufffd before every sentence.

有人可以帮我解决问题吗？

Could anybody help me solve the problem?

推荐答案

我可以想象服务器重新发送字节顺序标记（0xFFFE 0xFFFF），由客户端的替换字符（0xFFFD）替换。

在服务器端发送之前，您是否重新创建打印作者？

I could imagine that the server resends byte order markers (0xFFFE 0xFFFF), which are replaced by the replacement character (0xFFFD) at the client side.
Do you re-create the print writer before each send on the server side?
