Json 路径 - 如何仅从带有 "requests" 并给定 "title":"subject_2" 参数的部分获取 "id"？

Question

我有回复：

{"myRequests":[],

“请求”：[

{"id":"4919fe948-f4bb-4863","profileId":1,"comments":"","title":"subject_1" ...(bla-bla- bla)...,"名称":"Perf_1"},

{"id":"7295814a1-d1e7-440d","profileId":1,"comments":"","title":"subject_2" ...(bla-bla-bla)...,"name":"Perf_1"},

{"id":"0b548e6c2-ec40-4875","profileId":1,"comments":"","title":"subject_1" ...(bla-bla- bla)...,"名称":"Perf_1"},

{"id":"39c603faf-e3f7-4666","profileId":1,"comments":"","title":"subject_2" ...(bla-bla-bla)...,"name":"Perf_1"},

“批准的请求”：[

{"id":"83b8f6a65-da90-4b98","评论":"accept_1", ...(bla-bla-bla)...,"name":" =55=]"},

{"id":"4db544fd1-60fe-4b72","评论":"accept_1", ...(bla-bla-bla)...,"name":" =55=]"},

{"id":"24705ef9f-7c5c-4d43","评论":"accept_1", ...(bla-bla-bla)...,"name":" =55=]"},

{"id":"9d5238283-3da9-4d7d","评论":"accept_1", ...(bla-bla-bla)...,"name":" =55=]"}, ]}

我尝试使用

$.requests[?(@.comments=="")].id[0]

$.requests[?(@.comments=="" && @.title=="subject_2")].id[0]

但看不到效果 - 我缺少什么？

在这种情况下，正确的 json 路径应该是什么，只有来自带有“requests”和给定“title”的部分的“id”：“subject_2”参数？

我认为 JSON JMESPath Extractor and slightly amend your query to use pipe operator 这样会更容易：

requests[? comments==''].id | [0]
