db.getCollection('doc_views').aggregate([ { $match: { time: { $gte: "2020-03-29", $lte: "2021-03-29" } } }, { $group: { _id: { "name": '$docName' }, total: { $sum: "$count" } } }, { $lookup: { from: "docs", localField: "_id.name", foreignField: "name", as: "child" } }, { $project: { "child._id": false, "child.gitUrl": false, "child.description": false, "child.orgGroup": false, "child.orgPath": false, "child.newGit": false, "child.toTop": false, "child.docCollection": false, "child.opendFiles": false, "child.createTime": false, "child.logo": false, "child.orgName": false, "child.owner": false, "child.realName": false, "child.__v": false, "child.privateMember": false, "child.developer": false, "child.name": false } },])- $match 聚合匹配条件 这块是以doc_views表time字段匹配前端传入的起始工夫和截止时间段的所有数据
$group 按某些指定的表达式对文档进行分组，而后将每个不同的分组的文档输入到下一阶段。输入文档蕴含一个
_id字段，其中蕴含按关键字辨别的组- 这里以文档名称docName为关键字进行分组统计
- 同时给docName定义了一个name的别名 并包装到_id的对象上面
- 把所有以后时间段的同名文档进行合并并累计count字段输入total总数
$lookup 关联查问
参数 赋值 阐明 from "docs" 须要关联查问的表 此处查问的事主表docs localField "_id.name" 匹配查问数据的表的文档名称字段传参“_id.name”的起因是：aggregate管道模式数组上一个参数是下一个参数的入参 以后表文档名称关键字曾经被定义到_id对象外面了 foreignField "name" 匹配要联表的文档名称关键字 即docs表文档 名称关键字 as "child" 把以后匹配到的数据输入到as定义的别名 child外面 child是一个数组 留神：以摸一个关键字 如：文档名称 来聚合数据是 首先聚合进去的数据每个关键字只能有一条数据 否则联表时无奈匹配出关键字对应的主表数据
- $project 可指定显示或者疏忽联表外面的某些字段 如上所述 false示意不显示 true示意显示
