Javascript 聚合多个匹配项

Question

我正在尝试创建一个包含多个匹配项的聚合管道，但不确定该怎么做？！？

这是我正在尝试的：

const pipeline = [
  { match: { oomId: oomId, holes: 0, collectPutts: true } },
  { group: { 
    objectId: '$userId',
    puttsPlayed: { $sum: 1 },
    puts: {$sum: '$puts'},
    gir: {$sum: '$gir'},
    girHcp: {$sum: '$girHcp'}
  } },
  { match: { oomId: oomId, holes: 0, collectHits: true } },
  { group: { 
    objectId: '$userId',
    hits: {$sum: '$hit'},
    holesHit: {$sum: '$holesToHit'}
  } },
  { match: { oomId: oomId, holes: 0 },
  { group: { 
    objectId: '$userId',
    totalPlayed: { $sum: 1 },
    points: {$sum: '$points'},
    strokes: {$sum: '$strokes'}
  } },
  { project:{ 
      played: '$totalPlayed',
      puttsPlayed: '$puttsPlayed',
      puts: {$divide: ['$puts', '$puttsPlayed']},
      gir: {$divide: ['$gir', '$puttsPlayed']},
      girHcp: {$divide: ['$girHcp', '$puttsPlayed']},
      hits: '$hits',
      holesHit: '$holesHit',
      hitsPercentage: {
        $multiply: [
          { $divide: [ "$hits", "$holesHit" ] },
          100
        ]
      },
      points: {$divide: ['$points', '$totalPlayed']},
      strokes: {$divide: ['$strokes', '$totalPlayed']}
  }}
];

我收到此错误：意外标记“{”

不确定错误在哪里，甚至可以做我想做的事吗？还是我应该使用 3 个不同的管道？

感谢任何帮助...新聚合：-/

Answer 1

您在第 3 $match 阶段后没有关闭括号。所以，而不是这个：

{ match: { oomId: oomId, holes: 0 },

这样做：

{ match: { oomId: oomId, holes: 0 } },
