Java基础知识强化之网络编程笔记11：TCP之TCP协议上传文本文件

1. TCP协议上传文本文件（客户端上传数据到服务器端）

（1）客户端（上传数据到服务端）

 package cn.itcast_11;

 import java.io.BufferedReader;
 import java.io.BufferedWriter;
 import java.io.FileReader;
 import java.io.IOException;
 import java.io.OutputStreamWriter;
 import java.net.Socket;

 public class UploadClient {
     public static void main(String[] args) throws IOException {
         // 创建客户端Socket对象
         Socket s = new Socket("192.168.12.92", 11111);

         // 封装文本文件
         BufferedReader br = new BufferedReader(new FileReader(
                 "InetAddressDemo.java"));
         // 封装通道内流
         BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(
                 s.getOutputStream()));

         String line = null;
         while ((line = br.readLine()) != null) {
             bw.write(line);
             bw.newLine();
             bw.flush();
         }

         // 释放资源
         br.close();
         s.close();
     }
 }

（2）服务端（接收来自客户端的数据）

 package cn.itcast_11;

 import java.io.BufferedReader;
 import java.io.BufferedWriter;
 import java.io.FileWriter;
 import java.io.IOException;
 import java.io.InputStreamReader;
 import java.net.ServerSocket;
 import java.net.Socket;

 public class UploadServer {
     public static void main(String[] args) throws IOException {
         // 创建服务器端的Socket对象
         ServerSocket ss = new ServerSocket(11111);

         // 监听客户端连接
         Socket s = ss.accept();

         // 封装通道内的流
         BufferedReader br = new BufferedReader(new InputStreamReader(
                 s.getInputStream()));
         // 封装文本文件
         BufferedWriter bw = new BufferedWriter(new FileWriter("Copy.java"));

         String line = null;
         while ((line = br.readLine()) != null) {
             bw.write(line);
             bw.newLine();
             bw.flush();
         }

         bw.close();
         s.close();
     }
 }
