如何从JSON响应中获取数据

Question

例如，我试图从这种类型的JSON中获得_id：

[
    {
        "_id": 7,
        "baalut": "פרטי",
        "degem_cd": 558,
        "degem_manoa": "CVK",
        "degem_nm": "B8-8W2CDG",
        "horaat_rishum": 160046,
        "kinuy_mishari": "A4",
        "kvutzat_zihum": 7,
        "misgeret": "WAUZZZF46GA038023",
        "mispar_rechev": 2623638,
        "mivchan_acharon_dt": "2021-04-14T00:00:00",
        "moed_aliya_lakvish": "2016-3",
        "ramat_eivzur_betihuty": 1,
        "ramat_gimur": "LUXURY DSN",
        "rank": 0.0573088,
        "shnat_yitzur": 2016,
        "sug_degem": "P",
        "sug_delek_nm": "בנזין",
        "tokef_dt": "2022-03-08T00:00:00",
        "tozeret_cd": 19,
        "tozeret_nm": "אאודי",
        "tzeva_cd": 80,
        "tzeva_rechev": "שנהב לבן",
        "zmig_ahori": "245/35 R19",
        "zmig_kidmi": "245/35 R19"
    }
]

总的来说，这个JSON响应很长，所以我将删除不必要的响应。这是我的密码：

const json = await response.json();
console.log(json.result.records);

我得到了前面显示的结果，但是现在我想在JSON中获取数据，所以我尝试执行json.result.records._id，但它显示了undefined

我是json.result

Answer 1

您应该能够执行json.result.records._id，记录是一个数组。
