我是网络新手,在尝试运行MyClient.java时遇到 EOFException 。

MyServer.java

public class MyServer {
    public static void main(String[] args) {
        ServerSocket serverSocket = null;
        try {
            serverSocket = new ServerSocket(4321);
        } catch (IOException e) {
            e.printStackTrace();
        }
        while(true) {
            try {
                Socket socket = serverSocket.accept();
                OutputStream os =socket.getOutputStream();
                OutputStreamWriter osw = new OutputStreamWriter(os);
                BufferedWriter bw = new BufferedWriter(osw);
                bw.write("Hello networking");

                bw.close();
                socket.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

我的客户端.java

public class MyClient {
    public static void main(String[] args) {
        Socket socket = null;
        try {
            socket = new Socket("127.0.0.1", 4321);
            InputStream is = socket.getInputStream();
            DataInputStream dis = new DataInputStream(is);
            System.out.println(dis.readUTF());

            dis.close();
            socket.close();
        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (ConnectException e) {
            System.err.println("Could not connect");
        } catch (UTFDataFormatException e) {
            System.err.println("if the bytes do not represent a valid modified UTF-8 encoding of a string");
        } catch (EOFException e) {
            System.err.println("if this input stream reaches the end before reading all the bytes");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

如果这个输入流在读取错误的所有字节之前到达末尾,并且错误似乎是由dis.readUTF()调用引起的,我会得到。

有人可以帮我理解我错过了什么吗?我正在尝试读取服务器在连接时写入客户端的内容,即Hello network

谢谢。

问题出在你的服务器代码中,如果你想用 DataInputStream 读取它,你应该使用 DataOutputStream.writeUTF(String str) 来写入套接字。
