//分类module
    console.log('a')
    db.once('open',function(){
        console.log('b')
        var cat = mongoose.Schema({
            name:String,
            fid:Number,
            parentid:Number,
            type:String
        })

可以打印出’a’但是就是死活打印不了’b’。没有进入db.once(‘open’,funciton(){})回调函数里面,求解啊?

这个是post请求
