用了morgan打印出来的东西和老师的不一样为啥？

Question

结果：    Mongoose: users.ensureIndex({ name: 1 }) { unique: true, background: true, safe: undefined }

var logger = require('morgan')

if ('development' === app.get('env')) {

app.set('showStackError',true)

app.use(logger(':method :url :status'))

app.locals.pretty = true

mongoose.set('debug',true)

};
