node msgpack5 数据传输 简单实现

msgpack5

• nodeserver 部分

安装：
npm install msgpack5

• server代码 基于express 4.x

var msgpack = require(“msgpack5”)();
//设置类型
res.set(“Content-Type”, “application/msgpack”);
//数据格式化
var _data = msgpack.encode({
a:1,
b:2,
c:3
});
res.send(_data);

server全部相关代码

res.set("Content-Type", "application/msgpack");
res.header("Access-Control-Allow-Origin", "*");   
res.header("Access-Control-Allow-Headers", "X-Requested-With");
res.header("Access-Control-Allow-Methods", "PUT,POST,GET,DELETE,OPTIONS");
 var m = msg.encode({
    a: 1,
    c: 2,
    d: 5
 });
var lth = req.get("Content-Length");
console.log(lth);
req.on("data",function(e){
    console.log(msg.decode(e)) ;
})
res.send(m);

• client端

首先引用 msgpack.js

客户端全部相关代码

var oReq = new XMLHttpRequest();    
     oReq.open("POST", "http://localhost:9090", true);    
     oReq.responseType = "arraybuffer";    
var msg = msgpack5();    
     oReq.onload = function (oEvent) {    
var arrayBuffer = oReq.response;     
    if (arrayBuffer) {    
            var byteArray = new Uint8Array(arrayBuffer);    
            var s  = msg.decode(byteArray);    
            console.log(s);    
         }    
    };   
var data =  a.encode(["a","b","c","e"]);   
     oReq.send(data);
