//--------------koa2设置---------------------------

1.安装：

npm install koa-generic-session --save-dev

2.修改app.js

var session = require('koa-generic-session');

app.keys = ['my secret key'];

app.use(session());

 

3.代码

let user = {};

user.id=1;

user.nicheng = '张三';

ctx.session.user = user;

console.log(ctx.session.user);

console.log(ctx.session);

console.log(ctx.session.user);

-------------------设置session.loginbean代替传入的数据user-----------

ctx.session.loginbean = user;

ctx.body='登陆成功'
