我正在 Java 中實(shí)現(xiàn)套接字編程，其中我使用 BufferedReader 從客戶端獲取輸入。但是，BufferedReader 對(duì)象采用在控制臺(tái)上輸入的換行符。這是我的服務(wù)器端代碼：import java.net.*;import java.io.*;class FTPserver {private ServerSocket serverSocket = null;private DataInputStream dis = null;private DataOutputStream dos = null;FTPserver() {    try {        String input;        serverSocket = new ServerSocket(3000);        Socket socket = null;        socket = serverSocket.accept();        dis = new DataInputStream(socket.getInputStream());        dos = new DataOutputStream(socket.getOutputStream());        input = dis.readUTF();        if(input.equals("ftp")) {            dos.writeUTF("ftp> ");            input = dis.readUTF();            System.out.print("opened connection to 10.10.10.212");            dos.writeUTF("Connected to 10.10.10.212\n220 (vsFTPd 3.0.2)\nName (10.10.10.212:root): ");            input = dis.readUTF();            dos.writeUTF("331 Please specify the password.\nPassword: ");            input = dis.readUTF();            dos.writeUTF("230 Login successful.\nRemote system type is UNIX\nUse binary mode to transfer files\nftp> ");            input = dis.readUTF();       //receive mget            dos.writeUTF("ftp> ");            input = dis.readUTF();       //receive mput            dos.writeUTF("ftp> ");            //input = dis.readUTF();            input = dis.readUTF();       //receive exit            dos.writeUTF("Goodbye");            input = dis.readUTF();       //receive exit            dos.writeUTF("Goodbye");        }        dis.close();        dos.close();        socket.close();    }    catch(Exception e) {        e.printStackTrace();    }}public static void main(String[] args) {    FTPserver ftp = new FTPserver();}}這是我的客戶端代碼：import java.net.*;import java.io.*;import java.util.Scanner;class FTPclient {private DataInputStream dis = null;private DataOutputStream dos = null;private Socket socket = null;
