在 shell 脚本中使用 jq 过滤器从 stringify 对象获取 json 对象

Question

我正在编写 shell 脚本，因为我是新手。我的查询是我有 json 个对象

{
   "logo": {"name":"logo.png","type":"image\/jpeg","tmp_name":"C:\xampp\tmp\php8B97.tmp","error":0,"size":110290},
   "template":"template1",
   "firstname":"a",
   "lastname":"a",
   "username":"a",
   "password":"aa",
   "email":"a",
   "categoriesListArr":"{\"Women\":[\"All footwear\",\"All footwear\",\"All Clothing\",\"All Clothing\",\"All Watches\",\"All Watches\",\"All Sunglasses\",\"All Sunglasses\"],\"Men\":[\"All Mens Accessories\",\"All Bags,Belts And wallets\",\"All Fragrances\",\"All Grooming and wellness\"]}",
   "aboutUs":"aa",
   "contactUs":"78787878878787",
   "deliveryInfo":"aa",
   "privacyPolicy":"aa",
   "t&d":"aa"
}

我使用 jq 过滤器提取了 categoriesListArr 如下：

categories=`cat detail.json| jq '.categoriesListArr'`

detail.json 是文件名。现在类别是 stringify 对象...我需要解析它并将其转换为 json 对象。

"{\"Women\":[\"All footwear\",\"All footwear\",\"All Clothing\",\"All Clothing\",\"All Watches\",\"All Watches\",\"All Sunglasses\",\"All Sunglasses\"],\"Men\":[\"All Mens Accessories\",\"All Bags,Belts And wallets\",\"All Fragrances\",\"All Grooming and wellness\"]}"

我如何使用 jq 过滤器转换它

Answer 1

fromjson 是你的朋友:

$ jq '.categoriesListArr | fromjson' detail.json

或者，如果你想保留原来的结构：

$ jq '.categoriesListArr |= fromjson' detail.json

在 shell 脚本中使用 jq 过滤器从 stringify 对象获取 json 对象
