如何输出aggregate的结果？ - WXOPEN Club

请问一下如何输出aggregate后的结果？

const $ = db.command.aggregate

let temp=db.collection(‘recordmovement’).aggregate()

.match({

_openid: ‘5aO_tBixeUe2ULs6Z4fQ6yI’

})

.bucket({

groupBy: ‘$movement’,

boundaries: [‘1’, ‘50’],

default: ‘other’,

output: {

count: $.sum(‘$_id’),

ids: $.push(‘$_id’)

}

})

.end();

如果直接console.log(temp)，则直接输出Promise {[[PromiseStatus]]: “pending”, [[PromiseValue]]: undefined

const $ = db.command.aggregate

const p2 = db.collection(‘pay’).aggregate()

.match({

card: app.globalData.card

})

.group({

_id: ‘$period’

})

.end()

p2.then(result => {

if (result.list.length > 0) {

const mydata = [];

for (var i = 0; i < result.list.length; i++) {

mydata.push(result.list[i]._id)

}

mydata.sort().reverse();

this.setData({

dateArray: mydata, //获取数据数组

index: 0,

});

this.getData();

} else {

this.setData({

hidden: true

});

}

})
