jq 从路径中选择动态数据答案

【问题标题】：jq select with dynamic data from pathjq 从路径中选择动态数据

【问题描述】：

._source.offers_data[]|select(.shop_id == 2004).shop_name 有效，但我想用动态值 ._source.search_result_data.shop.id 替换 2004

所以我写了这个 ._source.offers_data[]|select(.shop_id == ._source.search_result_data.shop.id).shop_name 因为 ._source.search_result_data.shop.id 是一个数字，它似乎不是类型问题

    ], 
    "max_score": null, 
    "total": 3657
}, 
"timed_out": false, 
"took": 68
}

那么我必须在该语句中使用：

cat my.json | jq -c '.hits.hits[]|{products_ids: ._source.search_result_data.identifiers.id,best_shop_name: ._source.offers_data[]|select(.shop_id ==  ._source.search_result_data.shop.id)}

所以最终结果应该是：

{"products_ids":30671,"status":1,"note":"0.0000","is_exclusivity":null,"is_favorite":false,"is_new":false,"is_topsales":false,"price ":249.99,"promo_price":249.99,"grey_dot":true,"best_shop_name":"Stuff"}

【问题讨论】：

发布你的输入 json 结构

标签： jq

【解决方案1】：

jq解决方案：

jq '.hits.hits[]._source | .search_result_data.shop.id as $shop_id 
    | .offers_data[] | select(.shop_id == $shop_id).shop_name' jsonfile

输出：

"Stuff"

【讨论】：

@glitchtracker，将最终预期结果添加到您的问题中
但是如何把它放进去：cat my.json | jq -c '.hits.hits[]|{products_ids: ._source.search_result_data.identifiers.id,best_shop_name: ._source.offers_data[]|select(._source.search_result_data.shop.id==.shop_id).shop_name}
要使其在 {key_name: } 结构中工作，您需要加上括号。所以最终结果是： cat my.json | jq -c '.hits.hits[]|{products_ids: ._source.search_result_data.identifiers.id,best_shop_name: (._source.search_result_data.shop.id as $shop_id|._source.offers_data[]|select(.shop_id= =$shop_id).shop_name)}'
