如何比较不同数组中不同对象之间的对象属性

Question

我从 2 API 获取数据，一个 returns 来自 18 个不同机场的数据，一个 returns 从一个机场到另一个机场的航班（这个 API 需要输入出发机场和到达机场的id)

API returns 航班是这样的：

{
    "data": [
        {
            "id": 64,
            "airlineId": 8,
            "departureAirportId": 5,
            "arrivalAirportId": 2,
            "price": 205.75
        },
        {
            "id": 42,
            "airlineId": 7,
            "departureAirportId": 2,
            "arrivalAirportId": 17,
            "price": 1324.42
        }
    ]
}

而 returns 机场的 API 是这个：

{
    "data": [
        {
            "id": 1,
            "codeIata": "PSA",
            "latitude": 43.6931,
            "longitude": 10.3789
        },
        {
            "id": 2,
            "codeIata": "BLQ",
            "latitude": 44.5357,
            "longitude": 11.2736
        },
        {
            "id": 3,
            "codeIata": "BGY",
            "latitude": 45.6702,
            "longitude": 9.6715
        },
        {
            "id": 4,
            "codeIata": "MXP",
            "latitude": 45.6289,
            "longitude": 8.7183
        },
        {
            "id": 5,
            "codeIata": "TRN",
            "latitude": 45.1934,
            "longitude": 7.6158
        },
        {
            "id": 6,
            "codeIata": "VCE",
            "latitude": 45.5046,
            "longitude": 12.3444
        },
        {
            "id": 7,
            "codeIata": "FCO",
            "latitude": 41.8025,
            "longitude": 12.213
        },
        {
            "id": 8,
            "codeIata": "PSR",
            "latitude": 42.4261,
            "longitude": 14.1793
        },
        {
            "id": 9,
            "codeIata": "NAP",
            "latitude": 40.8819,
            "longitude": 14.2731
        },
        {
            "id": 10,
            "codeIata": "BRI",
            "latitude": 41.1375,
            "longitude": 16.763
        },
        {
            "id": 11,
            "codeIata": "BDS",
            "latitude": 40.6551,
            "longitude": 17.936
        },
        {
            "id": 12,
            "codeIata": "SUF",
            "latitude": 38.9057,
            "longitude": 16.2402
        },
        {
            "id": 13,
            "codeIata": "CTA",
            "latitude": 37.4667,
            "longitude": 15.0639
        },
        {
            "id": 14,
            "codeIata": "PMO",
            "latitude": 38.1813,
            "longitude": 13.0994
        },
        {
            "id": 15,
            "codeIata": "NRT",
            "latitude": 35.7653,
            "longitude": 140.386
        },
        {
            "id": 16,
            "codeIata": "KLX",
            "latitude": 37.0683,
            "longitude": 22.0256
        },
        {
            "id": 17,
            "codeIata": "ALA",
            "latitude": 43.3553,
            "longitude": 77.0447
        },
        {
            "id": 18,
            "codeIata": "PEK",
            "latitude": 40.0725,
            "longitude": 116.5975
        }
    ]
}

我需要从航班 API 中获取“departureAirportId”和“arrivalAirportId”，对照机场 API 检查它们并根据提供的 ID 获取机场名称。我尝试了很多方法，但每次我都挖了一个巨大的兔子洞，然后决定重新开始，因为我现在不知道有多少次了。

有什么建议吗？

这应该可以解决您的问题：

let flights = {
  "data": [{
      "id": 64,
      "airlineId": 8,
      "departureAirportId": 5,
      "arrivalAirportId": 2,
      "price": 205.75
    },
    {
      "id": 42,
      "airlineId": 7,
      "departureAirportId": 2,
      "arrivalAirportId": 17,
      "price": 1324.42
    }
  ]
};


let airports = {
  "data": [{
      "id": 1,
      "codeIata": "PSA",
      "latitude": 43.6931,
      "longitude": 10.3789
    },
    {
      "id": 2,
      "codeIata": "BLQ",
      "latitude": 44.5357,
      "longitude": 11.2736
    },
    {
      "id": 3,
      "codeIata": "BGY",
      "latitude": 45.6702,
      "longitude": 9.6715
    },
    {
      "id": 4,
      "codeIata": "MXP",
      "latitude": 45.6289,
      "longitude": 8.7183
    },
    {

      "codeIata": "TRN",
      "latitude": 45.1934,
      "longitude": 7.6158
    },
    {
      "id": 6,
      "codeIata": "VCE",
      "latitude": 45.5046,
      "longitude": 12.3444
    },
    {
      "id": 7,
      "codeIata": "FCO",
      "latitude": 41.8025,
      "longitude": 12.213
    },
    {
      "id": 8,
      "codeIata": "PSR",
      "latitude": 42.4261,
      "longitude": 14.1793
    },
    {
      "id": 9,
      "codeIata": "NAP",
      "latitude": 40.8819,
      "longitude": 14.2731
    },
    {
      "id": 10,
      "codeIata": "BRI",
      "latitude": 41.1375,
      "longitude": 16.763
    },
    {
      "id": 11,
      "codeIata": "BDS",
      "latitude": 40.6551,
      "longitude": 17.936
    },
    {
      "id": 12,
      "codeIata": "SUF",
      "latitude": 38.9057,
      "longitude": 16.2402
    },
    {
      "id": 13,
      "codeIata": "CTA",
      "latitude": 37.4667,
      "longitude": 15.0639
    },
    {
      "id": 14,
      "codeIata": "PMO",
      "latitude": 38.1813,
      "longitude": 13.0994
    },
    {
      "id": 15,
      "codeIata": "NRT",
      "latitude": 35.7653,
      "longitude": 140.386
    },
    {
      "id": 16,
      "codeIata": "KLX",
      "latitude": 37.0683,
      "longitude": 22.0256
    },
    {
      "id": 17,
      "codeIata": "ALA",
      "latitude": 43.3553,
      "longitude": 77.0447
    },
    {
      "id": 18,
      "codeIata": "PEK",
      "latitude": 40.0725,
      "longitude": 116.5975
    }
  ]
};

const findAirportByID = (airportID) => {
  return airports.data.filter(item => item.id == airportID);
}

flights.data.forEach(flight => {
    let departureAirport = findAirportByID(flight.departureAirportId);
  if(departureAirport[0])
    flight.deparureAirportCode = departureAirport[0].codeIata;
  let arrivalAirport = findAirportByID(flight.arrivalAirportId);
  if(arrivalAirport[0])
    flight.arrivalAirportCode = arrivalAirport[0].codeIata;
});

console.log(flights);
