我有两个集合，如清单和任务。两个模式如下所示

清单架构将如下所示

{
        "_id": "5b7d0f77e231b6b530b0ee5a",
        "audit_checklist_type": "Weekly"

    },
    {
        "_id": "5b7d3f33e7a57f38084efb09",
        "audit_checklist_type": "Daily"
    }

任务架构如下所示

    { 
        "_id": "5b7d65daf74be318e8378cf9",
        "checklist_id": "5b7d3f33e7a57f38084efb09"
    },
    {
        "_id": "5b7d662df74be318e8378cfb",
        "checklist_id": "5b7d3f33e7a57f38084efb09"
    }

我的查询是

AuditChecklist.aggregate([
{ $match: {
  $and: [
        audit_checklist_type : "Daily"
  ]
  } },
  {
     $lookup: {
        from: 'AuditTask',
        localField: '_id',
        foreignField: 'checklist_id',
        as: 'TaskData'
     }
  },


  ]).exec();

我正在尝试获得类似的输出

    {
        "_id": "5b7d3f33e7a57f38084efb09",
        TaskData": [
                    { 
                      "_id": "5b7d65daf74be318e8378cf9",
                      "checklist_id": "5b7d3f33e7a57f38084efb09"
                    },
                    {
                      "_id": "5b7d662df74be318e8378cfb",
                      "checklist_id": "5b7d3f33e7a57f38084efb09"
                    }
                   ]
    }

但对我来说，由此产​​生的 TaskData 输出是空的。任何帮助是极大的赞赏。提前致谢！

我在访问另一个容器中的一个容器路线时遇到问题。例如，我有两个微服务，分别称为user-service和api-gateway。我正在尝试访问api-gateway中的用户服务路由。

  const userServiceProxy = httpProxy(http://localhost:8093);
  this.app.post('/admin/register', async(req, res) => {

      userServiceProxy(req, res);

  });

 app.post('/admin/register', function (req, res) {
  res.send('POST request')
 })

 version: '3'
 services:
   api-gateway:
     container_name: api-gateway
     build: './api-gateway'
     ports:
       - "8080:8080"
     links:
       - user-service
   user-service:
     build: ./user-service
     container_name: user-service
     ports:
     - "8093:8093"
