Koa项目搭建过程详细记录

cnpm install -g koa-generator// 这里一定要用koa2koa2 /foo

app.use(require('koa-less')(__dirname + '/public'))

@import 'foo.less';@import 'bar.less';

// 设置app keys，session会根据这个进行加密app.keys = ['some secret hurr'];// 配置session configconst CONFIG = {  key: 'bougie:session',  /** (string) cookie key (default is koa:sess) */  maxAge: 1000 * 60 * 60 * 24 * 7,  overwrite: true,  /** (boolean) can overwrite or not (default true) */  httpOnly: true,  /** (boolean) httpOnly or not (default true) */  signed: true,  /** (boolean) signed or not (default true) */  rolling: true,  /** (boolean) Force a session identifier cookie to be set on every response. The expiration is reset to the original maxAge, resetting the expiration countdown. (default is false) */  renew: false,  /** (boolean) renew session when session is nearly expired, so we can always keep user logged in. (default is false)*/};// 应用中间件app.use(session(CONFIG, app));

// 赋值ctx.session.statu = value// 取值ctx.session.statu// 删除ctx.session.statu = null
