我有一个嵌入另一个 JSON 文档的 JSON 文档。我需要从嵌入文档中提取数据，但我不太熟悉 JSON 或jq.

以下是我的输入（guard.json）：

{
  "_index": "test-2021.06.02",
  "_type": "servrd",
  "_id": "ZWUxMDU5MjItOGY2MC00MGI5LWJhZTEtODRhYWQ1YTZhOGIy",
  "_version": 1,
  "_score": null,
  "_source": {
    "stream": "stdout",
    "time": "2021-10-02T03:13:52.496705721Z",
    "docker": {
      "container_id": "392923402349320329432h3432k4kj32kfks9s9sdfksdfjkdsjfsh3939322342"
    },
    "kubernetes": {
      "container_name": "test",
      "namespace_name": "dev",
      "pod_name": "test-dev-v004-9s885",
      "container_image": "localhost:80/pg/test:1.19.0",

      "labels": {

        "cluster": "test-dev",
        "load-balancer-test-dev": "true",
        "stack": "dev",
        "app_kubernetes_io/managed-by": "spinnaker",
        "app_kubernetes_io/name": "test",
        "moniker_spinnaker_io/sequence": "4"
      },
      "min_url": "https://100.400.0.22:443/api",
      "namespace_id": "jajdjsdf-dfse-dsf-koksls-sksjf030292",

      }

我试图用 jq 填充下面的 json 数据并期望输出如下

{
  "data": [
    {
      "topic_name": "BookShow",
      "topic_id": "ABCDFG",
      "urgency": "high"
    },
    {
      "topic_name": "AmzonMarket",
      "topic_id": "ESDCGHY",
      "urgency": "high"
    },
    {
      "topic_name": "AmzonMarket",
      "topic_id": "ESDCGHY",
      "urgency": "high"
    },
    {
      "topic_name": "BookShow",
      "topic_id": "ABCDFG",
      "urgency": "high"
    },
    {
      "topic_name": "bookTick",
      "topic_id": "KOLPUYDD",
      "urgency": "high"
    },
    {
      "topic_name": "bookTick",
      "topic_id": "KOLPUYDD",
      "urgency": "high"
    }
  ],
  "more": false,
  "limitations": 100,
  "range": 0
}

期望输出如下，这里“出现”将是新字段，用于计算出现次数。

"id","name","occurrences"
"KOLPUYDD","bookTick",2
"ABCDFG","BookShow",2
"ESDCGHY","AmzonMarket",2

请支持。
