javascript - 在 Java 脚本中访问已解析的 JSON 响应中的数组

Question

我有以下来自 API 的已解析 JSON 响应

emp = 
{
  "response": [
    {
      "image_fingerprint": null,
      "image_source_fingerprint": null,
      "last_name": "LastName",
      "location": "G564",
      "notes": "A great worker",
      "online_seating": {
        "seat_urls": []
      },
      "photo": "/images/employee.jpg",
      "seating": {
        "seated": "not seated",
        "seat_urls": [
                "/api/1/seats/33444",
                "/api/1/seats/55323",
                "/api/1/seats/62229"
            ]
      },
      "show_in_vd": true,
      "start_date": "2014-01-02",
    },

    {
      "image_fingerprint": null,
      "image_source_fingerprint": null,
      "last_name": "LastName",
      "location": "G564",
      "notes": "A great worker",
      "online_seating": {
        "seat_urls": []
      },
      "photo": "/images/employee.jpg",
      "seating": {
        "seated": "not seated",
        "seat_urls": [
                "/api/1/seats/56580",
                "/api/1/seats/69856",
                "/api/1/seats/50003"
            ]
      },
      "show_in_vd": true,
      "start_date": "2014-01-02",
    }
  ]
}

我需要将该响应中的数组 seat_urls 与以下数组进行比较

shiftA = ["/api/1/seats/50003","/api/1/seats/62229", "/api/1/seats/556565"]

如果 shiftA 中的任何 URL 与 emp.seat_urls 中的 URL 匹配，则返回来自 emp 的所有数据

我试过了

var shiftAEmp =  emp.seating.seat_urls.filter(value => shiftA.includes(value))

和许多其他人，但我不断收到 TypeError: Cannot read property 'seat_urls' of undefined

我尝试了其他过滤方法，但不幸的是它只是接缝我无法访问 JSON 文件 emp 中的 seat_urls (顺便说一句，有时 seats_urls cab=n 为空)

任何帮助将不胜感激

谢谢

请使用运行代码检查下面更新的 emp 对象:

var emp = {
  "response": [{
      "image_fingerprint": null,
      "image_source_fingerprint": null,
      "last_name": "LastName",
      "location": "G564",
      "notes": "A great worker",
      "online_seating": {
        "seat_urls": []
      },
      "photo": "/images/employee.jpg",
      "seating": {
        "seated": "not seated",
        "seat_urls": [
          "/api/1/seats/33444",
          "/api/1/seats/55323",
          "/api/1/seats/62229"
        ]
      },
      "show_in_vd": true,
      "start_date": "2014-01-02",
    },
    {
      "image_fingerprint": null,
      "image_source_fingerprint": null,
      "last_name": "LastName",
      "location": "G564",
      "notes": "A great worker",
      "online_seating": {
        "seat_urls": []
      },
      "photo": "/images/employee.jpg",
      "seating": {
        "seated": "not seated",
        "seat_urls": [
          "/api/1/seats/56580",
          "/api/1/seats/69856",
          "/api/1/seats/50003"
        ]
      },
      "show_in_vd": true,
      "start_date": "2014-01-02",
    }
  ]
};

var shiftA = ["/api/1/seats/50003","/api/1/seats/62229", "/api/1/seats/556565"];
var rd = emp.response.filter(r => r.seating.seat_urls.some(u => shiftA.includes(u)));

console.log(rd);
