Question

我想通过传递变量来查找。我有这样的数据，

using Newtonsoft.Json;

RootObject obj = JsonConvert.DeserializeObject<RootObject>(jsonString);
Console.WriteLine(obj.actList.Count);

在请求中，我正在获取这样的数据，

{
  "projectId": "12345-service-request",
  "projectVersion": [{
    "version":"1",
    "localConfig": [{
      "port": "3003",
      "mongoURI": "mongodb://localhost:27017/serviceRequest",
      "MQ": "RMQ",
      "logLevel": "2",
      "version": "1.1",
      "created": "03-06-2018 03:11:00 PM",
      "active": "N"
    },
    {
      "port": "3004",
      "mongoURI": "mongodb://localhost:27017/serviceRequest",
      "MQ": "IMQ",
      "logLevel": "1",
      "version": "1.2",
      "created": "07-06-2018 03:11:00 PM",
      "active": "Y"
    }]    
  }]
}

因此，我正在请求中更改{ "projectId" : "32804-service-request-service", "env" : "local" "cloudParam" : { "MQ" : "RMQ", "logLevel" : "2", "active": "N" } }的密钥。

cloudParam

现在，我想在“查找”查询中传递dbQry和projectId。我像下面这样传递，但是什么也没返回，

let dbQry = renameKeys(cloudParam, function(key, val) {
        return "projectVersion.localConfig."+ key;
    });

    console.log(dbQry);

    // Output : { 'projectVersion.localConfig.MQ' : 'RMQ', 'projectVersion.localConfig.logLevel': '2' , 'projectVersion.localConfig.active': 'N' }

那么，如何在Mongoose的Find方法中传递变量？

编辑- 预期输出：

ProjectConfig.find({'projectId' : projectId,dbQry}).exec(function(err,pc){         
    console.log("## DB Result : "+pc);
});

注意：如果我获得完整的文档作为输出，也可以，但是如何在find查询中传递参数。

尝试如下

ProjectConfig.findOne({ 'projectId': projectId }).exec(function (err, pc) {
let version = "1.1"; //your version
let MQ = "RMQ";//your mq
let versionData = {};
mydate.projectVersion.forEach(item => {
  let match = item.localConfig.find(ele=> (ele.version == version && ele.MQ == MQ ));
  versionData = (match != null) ? match : {}
});
    console.log(versionData);
});

控制台日志结果

{
      "port": "3003",
      "mongoURI": "mongodb://localhost:27017/serviceRequest",
      "MQ": "RMQ",
      "logLevel": "2",
      "version": "1.1",
      "created": "03-06-2018 03:11:00 PM",
      "active": "N"
    }
