Jigsaw-TCP 文档
1.1 简介
这是使用Jigsaw重新封装的TCP套接字,提供服务端和客户端两种实例工厂
1.2 动机
普通的,由操作系统接口提供的TCP套接字,虽然提供了keepAlive机制,但是间隔接近十分钟。
不适用于对资源的分配要求苛刻的环境。使用jigsaw.js封装后,所有TCP连接自带心跳包机制,
自动管理连接的存在,而通信仍然使用的是Node.js原生的TCP套接字。
其次,封装后的TCP套接字,使用jigsaw.js网络获取网络地址,轻松的发现网络内的服务端,并建立连接。
再者,由于jigsaw.js是基于JSON序列化与反序列化的,不适用于大量字节流的传送,
故本模块提供了"透明传送"的基于TCP的可靠高效字节流传送通道,jigsaw仅管理连接的存在,所以
不会影响到透传的性能。
1.2 安装
在npm项目下执行命令npm install ZhyMc/jigsaw-tcp --save
1.3 用例
1.3.1 简单用例
server.js
const {TCPClient,TCPServer} = require("jigsaw-tcp");
const {jigsaw,domainserver} = require("jigsaw.js")("127.0.0.1","127.0.0.1");
domainserver();
let jg=new jigsaw("jgtcpserver");
let server=new TCPServer(jg);
server.on("enter",(conn,id)=>{
console.log(id,"客户端加入了连接");
conn.on("data",(data)=>{
console.log("收到来自客户端的数据",data);
server.broadcast("欢迎你们");
});
});
server.on("leave",(conn,id)=>{
console.log(id,"客户端离开了连接");
});
client.js
const {TCPClient,TCPServer} = require("jigsaw-tcp");
const {jigsaw} = require("jigsaw.js")("127.0.0.1","127.0.0.1");
let jg=new jigsaw();
let client=new TCPClient(jg,"jgtcpserver");
client.on("ready",()=>{
console.log("连接TCP服务器成功");
let sock=client.getSocket();
sock.write("hello");
});
client.on("close",()=>{
console.log("连接已断开");
})
1.3.2 流的分发
streamServer.js
const {TCPClient,TCPServer} = require("jigsaw-tcp");
const {jigsaw,domainserver} = require("jigsaw.js")("127.0.0.1","127.0.0.1");
domainserver();
let jg=new jigsaw("streamserver");
let server=new TCPServer(jg);
server.on("enter",(conn,id)=>{
conn.on("data",(data)=>{
server.broadcast(data);
});
});
streamPublisher.js
const {TCPClient,TCPServer} = require("jigsaw-tcp");
const {jigsaw} = require("jigsaw.js")("127.0.0.1","127.0.0.1");
let jg=new jigsaw("streampublisher");
let publisher=new TCPClient(jg,"streamserver");
let chunkid=0;
publisher.on("ready",()=>{
let sock=publisher.getSocket();
setInterval(()=>{
sock.write("hello,i am chunk "+(chunkid++));
},100);
});
streamPlayer.js
const {TCPClient,TCPServer} = require("jigsaw-tcp");
const {jigsaw} = require("jigsaw.js")("127.0.0.1","127.0.0.1");
let jg=new jigsaw();
let player=new TCPClient(jg,"streamserver");
player.on("ready",()=>{
let sock=player.getSocket();
sock.on("data",(data)=>{
console.log(data.toString());
})
});
