Pocket API JSON解析

Question

我试图从Pocket API解析JSON以跟上我的书签。收到卷曲请求后收到的JSON如下：

我试图通过标签上的uri（尝试转换为csv）使输出看起来像这样：

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

我试过这个，但标签是嵌套的（consumer_key和access_token被编辑）：

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

在整改后使用您的示例输入使其成为有效的JSON：

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

收益率：

"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。如果您不想要所有的双引号，可以在尝试中使用字符串插值。

Answer 2

我加了一个？这适用（即使没有标签的条目）。 access_token和consumer_key在curl命令中被编辑。

注意：consumer_key和access_token都已替换为*

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

从jq手册：

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