全栈开发 - yog2 - 03 启用中间件cookie-session
方式一
1. project项目下安装npm包
1
npm install cookie-session --save
session模块可以给其它模块共享，所以安装在project下。
2. 创建插件文件
plugins/cookieSession/index.js

var session = require('express-session');
// 插件逻辑
module.exports.cookieSession = function(app, conf){
console.log('module.exports.cookieSession.conf.secret : ' + conf.secret);
return function(){
app.use(session(conf));
};
};
// 设置插件默认配置
module.exports.cookieSession.defaultConf = {
}
console.log 是我们设置的调试信息，一会运行起来 可以看到效果
3. 配置插件
修改文件 conf/plugins/http.js

*
* 配置中也可以通过function(req, res, next){}的形式加载中间件而无需使用插件管理

middleware: [
'favicon',
'compression',
'static',
'responseTime',
'cookieParser',
'bodyParser',
'log',
'ral',
'views',
'methodOverride',
'cookieSession',
'dispatcher',

'error'
]
};
...
// 这里是配置
module.exports.cookieSession = {
name: 'session',
keys: ['regtergrdg3425345wffbnyir768323453'],
secret : "afdds0098d7as879fdsuio3oih32jkljdsknzyi32",
maxAge: 24 * 60 * 60 * 1000 // 24 hours 单位毫秒，从设置cookie开始多少毫秒失效
}
加入 ‘cookieSession’ 注意执行的先后顺序 配置文件官方推荐放在
这个位置
4. app 端加入执行
文件 server/action/index.js

...
var cookieSession = require('cookie-session')
module.exports = function(req, res){
req.session.views = (req.session.views || 0) + 1;
console.log('session.views:'+req.session.views);
...
};
设置了
这个session key 可以执行看看了

这种方式有点很直接代码简单，缺点是代码层次结构不优雅，复杂的情况不好维护（如:组件依赖、异步回调）。
