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();
    }
}
