JQ：嵌套 JSON 转换

Question

我实际上正在寻找一种软件来转换我从网络 api 获得的 json 文件（我是一个完整的 json 新手），以便更好地加载到我的 SQL数据库。几个小时 Google 后来我发现了 jq，它几乎 100% 满足了我的需求。虽然我在 jq 上找到了满足我需要的必要过滤器操作，但现在在 "little" 问题中运行。我的源 json 嵌套很重，我需要从 json 路径中的不同层提取多个数据（来自 objects/Arrays）。我在 jqplay 上构建了以下过滤器：

. | {cruise_nid: .nid} + {nights: .nights} + {zone: .zones[].title} +  {sails_nid: .sails[].nid} + {arrival: .sails[].arrival} + {departure: .sails[].departure} + {cabintype: .sails[].cabins[].cabinType.kindName} + {catalogprice: .sails[].cabins[].catalogPrice} + {discountprice: .sails[].cabins[].discountPrice} + {currency: .sails[].cabins[].currency}

来源json（简称）：

}

从 json 来源 (100 kB) 我预计大约有 30 个这样的对象。但我收到 194481 个对象（大约 50 MB 文件）。我实际上不知道为什么会发生这种情况以及如何解决它。有什么想法吗？

谢谢

Answer 1

给定的输入样本不太有效JSON。以下假设已修复。
以下假设输出键名称的印刷情况可能更接近地反映输入键名称。
以下会产生所需的结果，但可能并不完全是您想要的，因为如果 .zones、.sails and/or .cabins 数组包含多个项目，则不清楚您的期望。

{nid, nights, zone: .zones[0].title} +
(.sails[0]
 | { sails_nid: .nid, arrival, departure } +
   (.cabins[0] 
    | { cabintype: .cabinType.kindName, catalogPrice, discountPrice, currency } ))

所有组合

如果您想要 "all combinations" 个区域、风帆和客舱，只需将上面的 [0] 替换为 [] 即可：

{nid, nights, zone: .zones[].title} +
(.sails[]
 | ({ sails_nid: .nid, arrival, departure } ) +
    (.cabins[] 
     | { cabintype: .cabinType.kindName, catalogPrice, discountPrice, currency } ) )

使用示例输入，这会发出 21 JSON objects。
