Question

我在Windows环境下使用jq 1.5修改给定的大型json文件，以从该大型文件中提取单个数组（“优惠”）：

'.Offers[] | ({Price: .AdultPriceEUR, Currency: .Currency, Link: .Deeplink, Tickettyp: .TicketClassIndex, Flightindex: .FlightIndex })'

之后，我得到了一个“未命名”数组。但是对于以后的处理，数组必须保留其旧的“名称”。我检查了文档并找到了setpath函数，但是提取时无法保持名称“ easy”吗？

缩短json文件的示例：

Answer 1

看起来像您在看这个

DataTable

它只是创建一个包含jq '{Offers:[.Offers[] | {Price: .AdultPriceEUR, Currency: .Currency, Link: .Deeplink, Tickettyp: .TicketClassIndex, Flightindex: .FlightIndex }]}' file表的新对象，并包含要放置它的内容。
