我想通过 imagePushedAt 和 imageTags 过滤数据集，其中应包含字符串 master。
我已经测试了以下内容

imageDetails[?imagePushedAt<`2024-04-27` && imageDetails.contains(@, `master`)]

但不幸的是这不起作用。 我在某种程度上通过使用这个查询得到了我想要的东西

imageDetails[?imagePushedAt < `2024-04-27`] | [].imageTags[?contains(@,`master`)]

但是当 imageTags 不匹配时，此解决方案返回空数组，而不是过滤掉结果

Answer 1

由于

imageTags

是一个数组，

imageTags.contains(@, `master`)

意味着您希望在

master

数组中严格等于

imageTags

的元素，而您的意思是 ”对于数组的每个元素，我都会执行字符串包含

master

”。

后者可以通过

表示

imageTags[?contains(@, `master`)]

因为，虽然

@

应用于数组时代表数组的一个元素，但这里它被 作为过滤器应用于数组的每个元素，因此

@

现在代表

imageTags 的每个字符串

数组。

所以，你的整个查询最终是：

imageDetails[?
  imagePushedAt<`2024-04-27` 
  && imageTags[?contains(@, `master`)]
]

在您的示例 JSON 中，这将产生单个元素：

[
  {
    "registryId": "259611133533",
    "repositoryName": "core",
    "imageDigest": "sha256:39239ba86a543aa6787da0a02479d6f59eb00742e4810a9d4b52f1423a5e0392",
    "imageTags": [
      "master-202404260911"
    ],
    "imageSizeInBytes": 470843809,
    "imagePushedAt": "2024-04-26T11:12:51+02:00",
    "imageManifestMediaType": "application/vnd.docker.distribution.manifest.v2+json",
    "artifactMediaType": "application/vnd.docker.container.image.v1+json",
    "lastRecordedPullTime": "2024-04-26T11:14:06.695000+02:00"
  }
