使用 jq 工具将文本从 txt 文件转换为 json

我有一个txt文件，其中的值是通过递归调用以下命令获得的:gsutil ls -r gs://bucket-test/** | while IFS= read -r key; do gsutil stat $key; done，如下所示:

gs://bucket-test/4e123978-8eed-43ae-f521-8fba54c704ea.zip:

我需要将输出转换为json格式，按前导空格拆分，并将每个组第一行上的值分配给"key"字段，然后可能会有子字段，例如在"METADATA"值下:

{
  "Key": "gs://bucket-test/4e123978-8eed-43ae-f521-8fba54c704ea.zip",
  "Creation time": "Wed, 21 Dec 2022 10:39:27 GMT",

  "Storage class": "STANDARD",
  "Content-Length": "0",
  "Content-Type": "application/zip",
  "Hash (crc32c)": "AAAAAA==",
  "Hash (md5)": "1B2M2Y8AsgTpgAmY7PhCfg==",
  "ETag": "CM30q9XCivwCEAE=",
  "Generation": "1671619167320653",
  "Metageneration": "1"
},
{
  "Key": "gs://bucket-test/GKiSQMZ5rAqrSWwur/uploads/GENERAL/SNrQD97nzQN9eDLeA/AAZYefiL5CT8pxe4L",
  "Creation time": "Mon, 10 Apr 2023 19:09:41 GMT",

  "Storage class": "STANDARD",
  "Content-Disposition": "inline; filename=James_INGREDIENTS_A3.pdf",
  "Content-Length": "4381797",
  "Content-Type": "application/pdf",
  "Hash (crc32c)": "GOzitA==",
  "Hash (md5)": "eUSLC/z70gjDB2WQKIPOuQ==",
  "ETag": "CLGPvu+BoP4CEAE=",
  "Generation": "1681153781106609",
  "Metageneration": "1"
},
{
  "Key": "gs://bucket-test/prova.pdf",
  "Creation time": "Mon, 08 May 2023 15:37:26 GMT",
  "Update time": "Mon, 08 May 2023 15:40:12 GMT",
  "Storage class": "STANDARD",
  "Content-Disposition": "inline; filename=James_KEY_VISUAL_A3.pdf",
  "Content-Language": "ace",
  "Content-Length": "15407",
  "Content-Type": "application/pdf",
  "Metadata": {
    "meta-1": "prova 1",
    "meta-2": "prova 2"
  },
  "Hash (crc32c)": "ZIrHPA==",

  "Metageneration": "3"
}

我try 对唯一的组使用此命令，但没有成功: gsutil stat gs://bucket-test/prova.pdf | printf %s "$(cat)" | jq -R -s 'split("\n") | map({key: split(": ")[0], value: split(": ")[1]})'个

将json转换为数组:

[
  {
    "key": "gs://spin8-test/prova.pdf:",
    "value": null
  },
  {
    "key": "    Creation time",
    "value": "         Mon, 08 May 2023 15:37:26 GMT"
  },
  {
    "key": "    Update time",
    "value": "           Mon, 08 May 2023 15:40:12 GMT"
  },
  {
    "key": "    Storage class",
    "value": "         STANDARD"
  },
  {
    "key": "    Content-Disposition",
    "value": "   inline; filename=James_KEY_VISUAL_A3.pdf"
  },
  {
    "key": "    Content-Language",
    "value": "      ace"
  },
  {
    "key": "    Content-Length",
    "value": "        15407"
  },
  {
    "key": "    Content-Type",
    "value": "          application/pdf"
  },
  {
    "key": "    Metadata",
    "value": "              "
  },
  {
    "key": "        meta-1",
    "value": "            prova 1"
  },
  {
    "key": "        meta-2",
    "value": "            prova 2"
  },
  {
    "key": "    Hash (crc32c)",
    "value": "         ZIrHPA=="
  },
  {
    "key": "    Hash (md5)",
    "value": "            oZbD+S8y35spkNozW3hUDA=="
  },
  {
    "key": "    ETag",
    "value": "                  CNDj09OG5v4CEAM="
  },
  {
    "key": "    Generation",
    "value": "            1683560246604240"
  },
  {
    "key": "    Metageneration",
    "value": "        3"
  }
]

有什么建议吗？谢谢
