Cách lấy value trong JSON

#1

Mình có file JSON theo cấu trúc sau. Các bạn cho Mình hỏi là mình chỉ muốn lấy các giá trị Id, Image, Title thì sao sao ah…??

[{
  "categories" : {
    "2be21d23-ae6d-4a57-b4aa-2cee130c7fab" : {
      "Id" : "2be21d23-ae6d-4a57-b4aa-2cee130c7fab",
      "Image" : "woman_01-s5-large-578.jpg",
      "Title" : "ACCESORIES"
    },
    "5669d0b2-8d90-4101-a60e-e8ff4998d9df" : {
      "Id" : "5669d0b2-8d90-4101-a60e-e8ff4998d9df",

      "Image" : "child-childrens-baby-children-s_shcevh.jpg",

Cậu có thể tách bằng jq:

echo '[{
  "categories" : {
    "2be21d23-ae6d-4a57-b4aa-2cee130c7fab" : {
      "Id" : "2be21d23-ae6d-4a57-b4aa-2cee130c7fab",
      "Image" : "woman_01-s5-large-578.jpg",
      "Title" : "ACCESORIES"
    },
    "5669d0b2-8d90-4101-a60e-e8ff4998d9df" : {
      "Id" : "5669d0b2-8d90-4101-a60e-e8ff4998d9df",
      "Image" : "story-winterwalk-imgsunglassesmoduler-large_1.jpg",
      "Title" : "WOMEN"
    },
    "c2a9fb38-12ee-4b60-bb6f-3faa1cb1e62b" : {
      "Id" : "c2a9fb38-12ee-4b60-bb6f-3faa1cb1e62b",
      "Image" : "james_bond_quote_1600x1200_1.jpg",
      "Title" : "MEN"
    },
    "e929051f-dfb6-4558-9ff9-26564a05b164" : {
      "Id" : "e929051f-dfb6-4558-9ff9-26564a05b164",
      "Image" : "child-childrens-baby-children-s_shcevh.jpg",
      "Title" : "KIDS"
    }
  }
}]' | jq '.[] | .categories | map(values) | .[] | .Id,.Image,.Title'

Output:

"2be21d23-ae6d-4a57-b4aa-2cee130c7fab"
"woman_01-s5-large-578.jpg"
"ACCESORIES"
"5669d0b2-8d90-4101-a60e-e8ff4998d9df"
"story-winterwalk-imgsunglassesmoduler-large_1.jpg"
"WOMEN"
"c2a9fb38-12ee-4b60-bb6f-3faa1cb1e62b"
"james_bond_quote_1600x1200_1.jpg"
"MEN"
"e929051f-dfb6-4558-9ff9-26564a05b164"
"child-childrens-baby-children-s_shcevh.jpg"
"KIDS"
