Question

我有一个JSON数据：

{
    "orderTotal_1": {
        "fields": {
            "button": {
                "actionDialog": null,
                "actionUrl": null,
                "clicked": false,
                "enable": true,
                "text": "LANJUTKAN KE PEMBAYARAN",
                "textColor": null
            },
            "payment": {
                "pay": "Rp1.953.800",
                "taxTip": "Termasuk PPN, jika berlaku.",
                "title": "Total"
            },
            "timestamp": 1522355946093
        },
        "id": "1",
        "tag": "orderTotal",
        "type": "biz"
        },
    "rightContainer_10010": {
        "fields": {
            "css": {
                "backgroundColor": null,
                "floatPosition": "right",
                "marginTop": null,
                "width": "388px"
            }
        },
        "id": "10010",
        "tag": "rightContainer",
        "type": "container"
    },
    "toPayBtn_10021": {
        "fields": {
            "clicked": false,
            "enable": true,
            "text": "LANJUTKAN KE PEMBAYARAN"
        },
        "id": "10021",
        "tag": "toPayBtn",
        "type": "biz"
    },
    "voucherInput_1": {
        "fields": {
            "buttonText": "GUNAKAN",
            "placeHolder": "Masukkan Kode Voucher",
            "status": "default"
        },
        "id": "1",
        "tag": "voucherInput",
        "type": "biz"
    }
}

我想获得toPayBtn_10021，但数字10021是动态的。所以它可以是toPayBtn_34 toPayBtn_21等等。

这是我想要实现的输出：

"toPayBtn_10021": {
    "fields": {
        "clicked": false,
        "enable": true,
        "text": "LANJUTKAN KE PEMBAYARAN"
    },
    "id": "10021",
    "tag": "toPayBtn",
    "type": "biz"
}

这就是我的尝试：

jq '.toPayBtn*'

但结果是：

jq: error: syntax error, unexpected $end (Unix shell quoting issues?) at <top-level>, line 1:
.toPayBtn*         
jq: 1 compile error
exit status 3

正则表达式似乎不能与jq一起使用我如何修复它？

Answer 1

with_entries( select(.key | test("^toPayBtn_")) )

生成您想要的输出。您可能想要调整正则表达式。
