从客户端到服务器端调用功​​能

Question

我已经完成了Node.js代码，它运行正常。但是，由于某些更改，我需要将代码放在server.js

下

client.js下的代码将数据附加到mongodb

＆＃13;

＆＃13;

var monitoredItem  = the_subscription.monitor({
           nodeId: opcua.resolveNodeId("ns=2000;s=TEST"),
           attributeId: opcua.AttributeIds.Value
       },
       {
           samplingInterval: 100,
           discardOldest: true,
          queueSize: 10
       },
       opcua.read_service.TimestampsToReturn.Both
       );
      console.log("-------------------------------------");
       
     monitoredItem.on("changed",function(dataValue){
		 console.log(" New Data Receive = ",dataValue.value.value);
		 
		 if(dataValue.value.value!='No New Data'){
			 var row = JSON.parse(dataValue.value.value);
			 if(row[0]!='Machine Unit'){
				 var machineUnit = row[0];
				 var airTemperature = row[1];
				 var waterTemperature = row[2];
				 var heatTemperature = row[3];
				 var roomTemperature = row[4];
				 var date = row[5];
				 var time = row[6];

				 MongoClient.connect('mongodb://127.0.0.1:27017/meiban', function(err, db) {
					   
					if (err) throw err;
						console.log("Connected to Database");
					   

					var document = {
					 
					  "machineUnit" : machineUnit,
					  "airTemperature" : airTemperature,		
					  "waterTemperature" : waterTemperature,
					  "heatTemperature" : heatTemperature,
					  "roomTemperature" : roomTemperature,
					  "date" : date,
					  "time" : time
					};
					  
						//insert record
					db.collection('meibandb').insert(document, function(err, records) {
						if (err) throw err;
						console.log("A new record added ! ");
					});
					
					
					
					db.close();
				
				});
			
			}
			
		 }
		 
          
     });
	  
    }
	,

现在，我需要将代码放到服务器端。我想要的代码附在下面。

＆＃13;

＆＃13;

if(dataValue.value.value!='No New Data'){
			 var row = JSON.parse(dataValue.value.value);
			 if(row[0]!='Machine Unit'){
				 var machineUnit = row[0];
				 var airTemperature = row[1];
				 var waterTemperature = row[2];
				 var heatTemperature = row[3];
				 var roomTemperature = row[4];
				 var date = row[5];
				 var time = row[6];

				 MongoClient.connect('mongodb://127.0.0.1:27017/meiban', function(err, db) {
					   
					if (err) throw err;
						console.log("Connected to Database");
					   

					var document = {
					 
					  "machineUnit" : machineUnit,
					  "airTemperature" : airTemperature,		
					  "waterTemperature" : waterTemperature,
					  "heatTemperature" : heatTemperature,
					  "roomTemperature" : roomTemperature,
					  "date" : date,
					  "time" : time
					};
					  
						//insert record
					db.collection('meibandb').insert(document, function(err, records) {
						if (err) throw err;
						console.log("A new record added ! ");
					});
					
					
					
					db.close();
				
				});
