如何输出aggregate的结果？
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
