mini-session 介绍
mini-
session是用于node.js的极简版session模块，非持久化。它的数据存储在内存里，因此，如果Web服务器进程重新启动，session将会丢失。所以，这个模块主要针对小网站，并没有太多的数据存储在session中。
安装
在使用 mini-session 之前， 你需要先安装 Cookies 包。
npm install cookies
然后
npm install mini-session
Demo
var http = require("http");
var Cookies = require("Cookies");
var Session = require("mini-session");
http.createServer(function(req, res){
var cookies = new Cookies(req, res);
var session = new Session(cookies);//init session with cookies
console.log("sessionId = " + session.sessionId);
session.set("userId", 123);
session.set("userName", "Jhon");
console.log("after set, session data is :");
session.dump();
console.log("session.get(\"userId\") = " + session.get("userId"));
session.abandon();
console.log("after abandon, session data is :");
session.dump();
res.writeHead(200, {"Content-Type":"text/html"});
res.end("<h1>session test done!</h1>");
}).listen(8500);
console.log("Server started : http://localhost:8500");
****控制台输出：
Server started : http://localhost:8500
sessionId = f4e4f42b130bfb4fb663ee67122c02b8
after set, session data is :
{ count: 1,
f4e4f42b130bfb4fb663ee67122c02b8: { count: 2, userId: 123, userName: 'Jhon' } }
session.get("userId") = 123
after abandon, session data is :
{ count: 0 }
