Node.js与Java通过Socket进行通信的实现方案

const net = require('net');
const fs = require('fs')
const server = net.createServer(function (connection) {
    console.log('客户端连接成功');
    connection.on('end', function () {
        console.log('客户端关闭连接');
    });
    connection.on('data', function (data) {
        console.log(data.toString());
    });
    const content = fs.readFileSync('./111.txt') // 读取到文件，进行返回
    connection.write('服务器：'+content.toString());
    // connection.pipe(connection); // 用来返回收到的消息，也就是服务端在这里收到的消息原文，再返回给客户端
});
server.listen(3000, function () {
    console.log('服务器监听');
});

const net = require('net');
const client = net.connect({ port: 3000 }, function () {
    console.log('连接到服务器！');
});
client.on('data', function (data) {
    console.log(data.toString());
    client.write("我已收到数据")
    client.end();
});
client.on('end', function () {
    console.log('断开与服务器的连接');
});

@Test
public void socket(){
    Socket socket = null;
    String Code_Adress = "127.0.0.1";
    try {
        socket = new Socket(Code_Adress,3000);
        OutputStream outputStream = socket.getOutputStream();
        InputStream inputStream = socket.getInputStream();
        byte[] bytes = new byte[1024];
        outputStream.write("我是JAVA客户端".getBytes());
        int len = inputStream.read(bytes);
        String str = new String(bytes,0,len);
        System.out.println(str);
        socket.close();
    } catch (IOException e) {
        e.printStackTrace();
    } 
}
