我已经发布了一个房间，房间被张贴在数据库中完美地改变预订状态为真。但其余的添加字段，如客户名称，日期，开始时间和结束时间字段被添加，但这些字段在数据库中为空。（注：使用mongodb）。

router.post('/booking',async(req,res)=>{
  await client.connect()
  try{
    data={
      customerName:"",
      date:"", 
      startTime:"",
      endTime:"",
      room_ID:""
    }
    const db =await client.db(dbName)
    let requests = await db.collection('RoomCreation').find({room_ID:req.body.room_ID}).toArray();//Getting the data
    console.log(requests)
    
    if(requests[0].Booked_Status===true){
      res.send({
        statusCode:400,
        message:"Room is full"
      })
    }
    else{
      let postroom=await db.collection('roombook').insertOne(req.body);//In another collection making entries
      let room=await db.collection("RoomCreation").findOneAndUpdate({room_ID:req.body.room_ID},{$set:{Booked_Status:true,customerName:req.body.customerName,date:req.body.date,startTime:req.body.startTime,endTime:req.body.endTime}}) //Updating the fields in main collection
      console.log(room)
      res.send({
        statusCode:200,
        data:room,
        data:postroom,
        message:"Room is created for you succesfully"
      })
    } 
   
  }
  catch(error){
    console.log(error)
    res.send({
      statusCode:500,
      message:"Internal Server Error",
      booked:false,
      error
    })
  }
  finally{
    client.close()
  }        
})

输入/输出：

{
"Customer_Name":"kranthi",
"Date":"03-01-2022",
"Start_Time":"19:00",
"End_Time":"23:00",
"room_ID":"201"
}
