我实际上正在寻找一个软件来转换我从web api获得的json文件（我是一个完整的json noobie），以便更好地加载到我的SQL数据库。几个小时谷歌研究后来我发现了jq，这几乎达到了我的需求100％。 我虽然为了我的需要在jq上找到了必要的过滤器操作，但现在运行的是“小”问题。我的源json是大量嵌套的，我需要从jsons路径中的不同层提取多个数据（来自对象/数组）。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}

结果如下：

从json源码（100 kB）我预计会有30个这样的对象。但是我收到了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我如何解决它。有什么想法吗？

答案 0 :(得分：0)
{nid, nights, zone: .zones[0].title} +
(.sails[0]
| { sails_nid: .nid, arrival, departure } +
(.cabins[0]
| { cabintype: .cabinType.kindName, catalogPrice, discountPrice, currency } ))
如果您想要区域，风帆和小屋的“所有组合”，只需将[0]替换为上面的[]：
{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个JSON对象。
