用文件中的字符串值修改json数组

Question

我有一个像这样的json文件：

{
"header": "headername",
"arrays": [
    "a_string",
    {
      "name": "foo",
      "properties": [
        {
          "type": "some_type1",
          "url": "https://example.com",
          "checksum": "d6fd580fe890b826250aa5d5a88bcdb28839cff4d447ba51536cda4ceae89c4e"
        }
      ]
    },
    "another_string",
    {
      "name": "bar",
      "properties": [
        {
          "type": "some_type2",
          "url": "https://example.org",
          "checksum": "d6fd580fe890b826250aa5d5a88bcdb28839cff4d447ba51536cda4ceae89c4e"
        }
      ]
    }
  ]
}

我想更改

properties

为

name

的数组中的

foo

块。预期输出是：

{
"header": "headername",
"arrays": [
    "a_string",
    {
      "name": "foo",
      "properties": [
        {
          "type": "foo",
          "url": "bar"
        }
      ]
    },
    "another_string",
    {
      "name": "bar",
      "properties": [
        {
          "type": "some_type2",
          "url": "https://example.org"
        }
      ]
    }
  ]
}

类似

.arrays[]| select(.name == "foo").sources |= [{"type" : "foo", "url" : "bar"}]

的结果是

jq: error (at <stdin>:26): Cannot index string with string "name"

并且

.| select(.name == "foo").sources |= [{"type" : "foo", "url" : "bar"}]

可以解析它，但不会改变任何内容。

你很接近。试试这个：

.arrays |= map(objects | select(.name == "foo") .properties = [{type : "foo", url : "bar"}])
