The solution of sticky package problem of TCP for Node.Js !

'use strict';

const net = require('net');
const stick_package = require('../../index').stick;

const tcp_server = net.createServer(function (socket) {
    socket.stick = new stick_package(1024).setReadIntBE('32');
    socket.on('data', function (data) {
        socket.stick.putData(data);
    });

    socket.stick.onData(function (data) {
        // 解析包头长度
        const head = new Buffer(4);
        data.copy(head, 0, 0, 4);

        // 解析数据包内容
        const body = new Buffer(head.readInt32BE());
        data.copy(body, 0, 4, head.readInt32BE());

        console.log('data length: ' + head.readInt32BE());
        console.log('body content: ' + body.toString());
    });

    socket.on('close', () => {
        console.log('client disconnected');
    });

    socket.on('error', error => {
        console.log(`error:客户端异常断开: ${error}`);
    });
});

tcp_server.on('error', function (err) {
    throw err;
});
tcp_server.listen(8080, function () {
    console.log('tcp_server listening on 8080');
});
