猫鼬查询的JSON响应显示不正常

Question

我有以下猫鼬模式

const analyticsSchema = new mongoose.Schema({
  All_Rehires_Processed: Number,
  All_Unique_Rehires_Processed: Number,
  Files_Generated: Number,
  Files_Generated_By_Position: {
    Core: {
      Server: {
        Server0: Number,
        Server1: Number,
        Server2: Number,
        Server3: Number
      }
    },
    Nop: {
      Server: {
        Server0: Number,
        Server1: Number,
        Server2: Number,
        Server3: Number
      }
    }
  },
  Rehires_By_Position: {
    Core: {
      Server: {
        Server0: Number,
        Server1: Number,
        Server2: Number,
        Server3: Number
      }
    },
    Nop: {
      Server: {
        Server0: Number,
        Server1: Number,
        Server2: Number,
        Server3: Number
      }
    }
  }
});

当我检查数据库中的数据时，它将以正确的顺序返回结果。 我跑

db.getCollection('analytics').find({}).pretty()

它返回正确的顺序。

{
  "_id": "5bdeafda975df6b565bfed2a",
  "All_Rehires_Processed": 137,
  "All_Unique_Rehires_Processed": 108,
  "Files_Generated": 41,
  "Files_Generated_By_Position": {
    "Core": {
      "Server": {
        "Server0": 1,
        "Server1": 1,
        "Server2": 1,
        "Server3": 1
      }
    },
    "Nop": {
      "Server": {
        "Server0": 0,
        "Server1": 1,
        "Server2": 1,
        "Server3": 1
      }
    }
  },
  "Rehires_By_Position": {
    "Core": {
      "Server": {
        "Server0": 30,
        "Server1": 30,
        "Server2": 14,
        "Server3": 11

      }
    },
    "Nop": {
      "Server": {
        "Server0": 0,
        "Server1": 1,
        "Server2": 1,
        "Server3": 1
      }
    }
  },
  "__v": 0
}

我当前正在将数据返回到明示端点

app.get('/analytics', (req, res) => {
  Analytics.find({}, (err, analytics) => {
    if (err) throw err;
    // check if analytics
    if (!analytics || analytics.length === 0) {
      return res.status(404).json({
        error: 'No files exist'
      });
    }
    //analytics exist
    return res.json(analytics);
  });
});

这有效并以错误的顺序返回了我期望的数据。它按以下顺序返回数据

{
  "Files_Generated_By_Position": {
    "Core": {
      "Server": {
        "Server0": 1,
        "Server1": 1,
        "Server2": 1,
        "Server3": 1
      }
    },
    "Nop": {
      "Server": {
        "Server0": 0,
        "Server1": 1,
        "Server2": 1,
        "Server3": 1
      }
    }
  },
  "Rehires_By_Position": {
    "Core": {
      "Server": {
        "Server0": 30,
        "Server1": 30,
        "Server2": 14,
        "Server3": 11

      }
    },
    "Nop": {
      "Server": {
        "Server0": 0,
        "Server1": 1,
        "Server2": 1,
        "Server3": 1
      }
    }
  },
  "_id": "5bdeafda975df6b565bfed2a",
  "All_Rehires_Processed": 137,
  "All_Unique_Rehires_Processed": 108,
  "Files_Generated": 41,
  "__v": 0
}

返回Express端点时，是否有任何方法可以强制json对象维持顺序？我需要对它进行排序还是我做错了什么？
