简版的文件传输

利用TCP协议下一个简版的文件传输

发送文件客户端

package Package1;

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;

public class 发送文件客户端 {

    public static void main(String[] args) throws IOException, IOException {
        try(
                Socket s=new Socket(InetAddress.getByName("localhost"),9002);
                BufferedInputStream  bis=new BufferedInputStream(new FileInputStream(new File("C:\Users\Administrator\Desktop\4.19.txt")));
                BufferedOutputStream bos=new BufferedOutputStream(s.getOutputStream());
                
                ){
                    byte[] bt=new byte[1024];
                    int count=0;
                    while((count=bis.read(bt))!=-1) {
                        bos.write(bt,0,count);
                    }
                    bos.flush();
        }catch(Exception e) {
            e.printStackTrace();
        }

    }

服务器端：

package Package1;

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;

public class 发送文件服务器端 {

    public static void main(String[] args) throws Exception {
        try(
                ServerSocket ss=new ServerSocket(9002);
                
                ){
                    try(
                            Socket s=ss.accept();
                        BufferedInputStream bis=new BufferedInputStream(s.getInputStream());                        
                        BufferedOutputStream bos=new BufferedOutputStream(new FileOutputStream(new File("upload\2.txt")));
                            
                            ){
                            byte[] bt=new byte[1024];
                            int count=0;
                            while((count=bis.read())!=-1) {
                                bos.write(bt,0,count);
                            }
                    }
        }

    }
