我尝试了一些方法，但我的目标只是获得对 last 的访问权限，例如，在对 2021-02-12:5 和 610.0 部分使用通配符时。
{ symbol:symbol,test:putExpDateMap.*.[*].last} 是我最接近成功的地方，但没有雪茄，感谢有关如何编写最有效的查询以仅访问这些属性中的几个而不是所有属性的任何帮助。

答案 0 :(得分：0)
您的查询确实有两个问题：
putExpDateMap.* 不会为您提供任何级别的未知属性，而只会提供一个级别。由于第一项将通过 putExpDateMap."2021-02-12:5"."610.0" 静态访问，这意味着您必须使用两个通配符来访问嵌套在那里的数组，因此 putExpDateMap.*.*[*] 但它不是一个属性，所以应该是 putExpDateMap."2021-02-12:5"."610.0"[*] 而不是 putExpDateMap."2021-02-12:5"."610.0".[*]，或者 putExpDateMap.*.*[*]而不是putExpDateMap.*.[*]喜欢你的尝试。最后但并非最不重要的是，使用更正的查询：
{ symbol:symbol,test:putExpDateMap.*.*[*].last }
你仍然以混乱的输出结束：
{
"symbol": "TSLA",
"test": [
[
[
2.36
]
],
[
[
3.4
]
],
[
[
4.2
]
],
[
[
5.35
]
],
[
[
9.56
]
],
[
[
15.64
]
],
[
[
40.25
]
],
[
[
49.45
]
]
]
}
因为通配符正在创建一些新级别的数组 — 因为您可以拥有保存数组的 * 属性。
您可能需要阅读 JMESPath flatten operator [] 以解决这个问题。
所以，我们以：
{ symbol:symbol, test:putExpDateMap.*.*[*].last[][] }
这给出：
{
"symbol": "TSLA",
"test": [
2.36,
3.4,
4.2,
5.35,
9.56,
15.64,
40.25,
49.45
]
}
