nodejs博客遇到的问题

1、express-session deprecated undefined resave option; provide resave option app.js:49:9

express-session deprecated undefined saveUninitialized option; provide saveUninitialized option app.js:49:9

解答：其实我们可以看到红色的部分就是导致错误的原因；解决办法：

app.use(session({ secret: ‘keyboard cat‘, cookie: { maxAge: 60000 }, resave: true, saveUninitialized: true }))具体参看https://github.com/expressjs/session#options2、failed to load c++ bson extension using pure js version在package.json修改  “connect-mongo”:“0.8.2” 运行npm install安装模块,打开app.js，添加以下代码：

app.use(session({
  secret: settings.cookieSecret,
  key: settings.db,//cookie name
  cookie: {maxAge: 1000 * 60 * 60 * 24 * 30},//30 days
  store: new MongoStore({
    db: settings.db,
    host: settings.host,
    port: settings.port,
    url: ‘mongodb://localhost/myblog‘
  }),
  proxy: true,
  resave: true,
  saveUninitialized: true
