Question

我正在尝试从Pocket API解析JSON，以跟上我的书签。在curl请求后收到的JSON如下所示：

  "list": {
    "1548784635": {
      "item_id": "1548784635",

          "tag": "fields"
        },
        "jq": {

      },
      "authors": {
        "45850780": {
          "item_id": "1548784635",
          "author_id": "45850780",
          "name": "abraham",
          "url": "https://stackoverflow.com/users/26406/abraham"
        },
        "82251593": {

      },
      "images": {

      },

greyscale=true"
      },
      "listen_duration_estimate": 121
    },
...

我试图通过标签上的uri使输出看起来像这样（试图转换为csv）：

https://stackoverflow.com/questions/28164849/using-jq-to-parse-and-display-multiple-fields-in-a-json-serially
fields, jq, multiple

我尝试过此操作，但是标签是嵌套的（consumer_key和access_token已编辑）：

curl https://getpocket.com/v3/get --insecure -X POST -H "Content-Type: application/json" -H "X-Accept: application/json" -d "{\"consumer_key\":\"*\", \"access_token\":\"*\", \"detailType\":\"complete\"}" | jq '.list[] | "\(.given_url) \(.tags)"'

Answer 1

在更正后使用示例输入使其成为有效的JSON：

jq -r '.list[] | [.given_url] + (.tags|keys_unsorted) | @csv' input.json

产量：

"https://stackoverflow.com/questions/28164849/using-jq-to-parse-and-display-multiple-fields-in-a-json-serially","fields","jq","multiple"

这是有效的CSV。如果您不希望所有的双引号都可以，请尝试使用字符串插值。

Answer 2

我加了一个？。这有效（即使没有标签的条目也是如此）。在curl命令中修改了access_token和consumer_key。

注意：consumer_key和access_token均已替换为*

curl https://getpocket.com/v3/get --insecure -X POST -H "Content-Type: application/json" -H "X-Accept: application/json" -d "{\"consumer_key\":\"80793-861ab2c92e846c8324b417e8\", \"access_token\":\"b6b55049-fe0a-df88-8f78-eb9ccc\", \"detailType\":\"complete\"}" | jq -r '.list[] | [.given_url] + (.tags|keys_unsorted?) | @csv' | less

摘自jq手册：

.[]?
       Like .[], but no errors will be output if . is not an array or object.
