koa-generic-session set error: Cannot read property 'maxAge' of undefined

[sumaolin]

koa-generic-session 和 koa-generic-session-mongo 中相关的配置： app.js

app.use(session({
  store: new MongoStore(config.mongodb)
}));

config/default.js

  mongodb: {
    url: 'mongodb://127.0.0.1:27017/club'
  },

每次post /signin 时候执行到 routes/signin.js

  this.session = {
    user: userInfo.name,
    email: userInfo.email
  };

就报错：

koa-generic-session set error: Cannot read property 'maxAge' of undefined

检查浏览器是否把Cookie禁用了

[sumaolin]

不是浏览器Cookie 的问题，用了给别的方法解决了 app.js session 设置

app.use(session({
  store: new MongoStore(config.mongodb),
  beforeSave: function(ctx, sess){
    ctx.session.cookie = sess.cookie = {
      httpOnly: true,
      path: '/',
      overwrite: true,
      signed: true,
      maxAge: 24 * 60 * 60 * 1000 //one day in ms
    };
  }
}));

效果实现了，不知道有啥影响不！
