[学习交流] TCP上传文本文件加服务器端返回

开始写的那个没加结束符
重新写一个
服务端

package com.cn.test2;
import java.io.*;
import java.net.*;
public class TCPFileServer {
public static void main(String[] args) throws Exception {
System.out.println("服务端开启……");
ServerSocket ss=new ServerSocket(5246);
Socket s=ss.accept();
BufferedReader br=new BufferedReader(new InputStreamReader(s.getInputStream()));//接收的
PrintWriter pw=new PrintWriter(new FileWriter("TCPRcv.txt"),true);
String line=null;
while((line=br.readLine())!=null){
pw.println(line);
}
//上传成功后给客户端一个提示
PrintWriter pwAfter=new PrintWriter(s.getOutputStream(),true);
pwAfter.println("上传完成");
pw.close();
s.close();
ss.close();
}
}

客户端

package com.cn.test2;
import java.io.*;
import java.net.*;
public class TCPUpFileClient {
public static void main(String[] args) throws Exception {
System.out.println("客户端开启……");
Socket s=new Socket(InetAddress.getByName("192.168.1.4"),5246);
BufferedReader br=new BufferedReader(new FileReader("ForTCP.txt"));
PrintWriter pw=new PrintWriter(s.getOutputStream(),true);
String line=null;
while((line=br.readLine())!=null){
pw.println(line);
}
s.shutdownOutput();//表示关闭输出流
BufferedReader brAfter=new BufferedReader(new InputStreamReader(s.getInputStream()));
String str=brAfter.readLine();
System.out.println(str);
br.close();
s.close();
}
}
