Json JQ获取嵌套数组的错误输出

我正在尝试使用JQ将json文件转换为csv文件。我已经设法对文件执行了此操作，但在测试期间，我发现输出并不像预期的那样。我花了好几个小时试图修好它，但似乎到不了那里，请你帮忙

理想情况下，我也想将用户和组合并为一个，但我可以不这样做

这是我的json文件的精简版本

[
  {
    "id": 319,
    "policyItems": [
      {
        "accesses": [
          {
            "type": "consume",
            "isAllowed": true
          },
          {
            "type": "create",
            "isAllowed": true
          }
        ],
        "users": [
          "foo"
        ],
        "groups": []
      },
      {
        "accesses": [
          {
            "type": "publish",
            "isAllowed": true
          },
          {
            "type": "create",
            "isAllowed": true
          }
        ],
        "users": [],
        "groups": [
          "bar"
        ]
      }
    ]
  },
  {
    "id": 320,
    "policyItems": [
      {
        "accesses": [
          {
            "type": "publish",
            "isAllowed": true
          },
          {
            "type": "create",
            "isAllowed": true
          }
        ],
        "users": [
          "foo"
        ],
        "groups": []
      },
      {
        "accesses": [
          {
            "type": "consume",
            "isAllowed": true
          },
          {
            "type": "create",
            "isAllowed": true
          }
        ],
        "users": [],
        "groups": [
          "bar"
        ]
      }
    ]
    }
]

我尝试了这个JQ代码的各种版本，但是对于id=319，user=foo应该有访问消费和创建的权限，而group=bar应该有访问发布和创建的权限。但我总是以foo和bar都可以访问消费、发布和创建（或其他错误）而告终

我试过：

cat file.json | jq -r '[.[] | select(has("policyItems")) |{"id", "users":(.policyItems[] | .users), "groups":(.policyItems[] | .groups), "access_type":([.policyItems[].accesses[] | .type])} ] '

输出：

      [
      {
        "id": 319,
        "users": [
          "foo"
        ],
        "groups": [],
        "access_type": [
          "consume",
          "create",
          "publish",
          "create"
        ]
      },
      {
        "id": 319,
        "users": [
          "foo"
        ],
        "groups": [
          "bar"
        ],
        "access_type": [
          "consume",
          "create",
          "publish",
          "create"
        ]
      },
      {
        "id": 319,
        "users": [],
        "groups": [],
        "access_type": [
          "consume",
          "create",
          "publish",
          "create"
        ]
      },
      {
        "id": 319,
        "users": [],
        "groups": [
          "bar"
        ],
        "access_type": [
          "consume",
          "create",
          "publish",
          "create"
        ]
      },
      {
        "id": 320,
        "users": [
          "foo"
        ],
        "groups": [],
        "access_type": [
          "publish",
          "create",
          "consume",
          "create"
        ]
      },
      {
        "id": 320,
        "users": [
          "foo"
        ],
        "groups": [
          "bar"
        ],
        "access_type": [
          "publish",
          "create",
          "consume",
          "create"
        ]
      },
      {
        "id": 320,
        "users": [],
        "groups": [],
        "access_type": [
          "publish",
          "create",
          "consume",
          "create"
        ]
      },
      {
        "id": 320,
        "users": [],
        "groups": [
          "bar"
        ],
        "access_type": [
          "publish",
          "create",
          "consume",
          "create"
        ]
      }
      ]

我还尝试：

cat file.json | jq  ' map({id, "access_type":([.policyItems[].accesses[] | .type])[], "users":(.policyItems[] | .users)[], "groups":(.policyItems[] | .groups)}) '

它提供输出：

    [
{
    "id": 319,
    "access_type": "consume",
    "users": "foo",
    "groups": []
  },
  {
    "id": 319,
    "access_type": "consume",
    "users": "foo",
    "groups": [
      "public"
    ]
  },
  {
    "id": 319,
    "access_type": "create",
    "users": "foo",
    "groups": []
  },
  {
    "id": 319,
    "access_type": "create",
    "users": "foo",
    "groups": [
      "public"
    ]
  },
  {
    "id": 319,
    "access_type": "publish",
    "users": "foo",
    "groups": []
  },
  {
    "id": 319,
    "access_type": "publish",
    "users": "foo",
    "groups": [
      "public"
    ]
  },
  {
    "id": 319,
    "access_type": "create",
    "users": "foo",
    "groups": []
  },
  {
    "id": 319,
    "access_type": "create",
    "users": "foo",
    "groups": [
      "public"
    ]
  },
  {

    "access_type": "publish",

    "groups": []
  },
  {
    "id": 320,
    "access_type": "publish",
    "users": "foo",
    "groups": [
      "public"
    ]
  },
  {
    "id": 320,

    "access_type": "create",
    "users": "foo",
    "groups": [
      "public"
    ]
    }
    ]

提前谢谢

编辑： 我期望的输出是这样的，用户和组被组合在一起，并正确地显示正确的访问

  [
  {
    "id": 319,
    "users_groups": [
      "foo",
      "bar"
    ],
    "access_type": [
      "create"
    ]
  },
  {
    "id": 319,
    "users_groups": [
      "foo"
    ],
    "access_type": [
      "consume"
    ]
  },
  {
    "id": 319,
    "users_groups": ["bar"],
    "access_type": [
      "publish"
    ]
  },
  ...

我想你想要这样的东西：

# Print out your top example input
echo '{"id":319,"policyItems":[{"accesses":[{"type":"consume","isAllowed":true},{"type":"create","isAllowed":true}],"users":["foo"],"groups":[]},{"accesses":[{"type":"publish","isAllowed":true},{"type":"create","isAllowed":true}],"users":[],"groups":["bar"]}]}
{"id":320,"policyItems":[{"accesses":[{"type":"publish","isAllowed":true},{"type":"create","isAllowed":true}],"users":["foo"],"groups":[]},{"accesses":[{"type":"consume","isAllowed":true},{"type":"create","isAllowed":true}],"users":[],"groups":["bar"]}]}' \
| jq -n '[inputs | .id as $id | .policyItems[] | {"id": $id, "access_type": (reduce .accesses[].type as $item ([]; . + [$item])), "users_groups": (.users + .groups)}]'

下面是正在发生的事情：

• echo'{“id”：…

  我们正在回显您的输入

• |jq

  将管道连接到

  jq

• jq-n'[inputs |…]

  我们接受

  jq

  中的回显输入作为流式过滤器

  输入（而不是
  ），以便我们一次处理整个输入，以便将结果包装在外括号中。
  
  -n
  在这里很重要，因为它指示
  jq
  不要隐式使用管道输入
  

• .id为$id

  我们将父id保存到

  $id

  变量中以供将来参考

• | policyItems[]

  我们正在迭代policyItems数组，您似乎希望根据该数组对结果进行分组

• {“id”：$id，

  这里我们开始构建结果，并返回到我们保存的

  $id

• “访问类型”：（reduce.accesss[].type为$item（[]；.+[$item]），…

  这里我们使用

  reduce

  过滤器将访问类型组合到单个数组中

• “用户组”：（.users+.groups）}

  我们最终将

  “用户”

  和

  “组”

  数组合并为一个数组

所有这些都允许我们返回如下输出：

[
  {
    "id": 319,
    "access_type": [
      "consume",
      "create"
    ],
    "users_groups": [
      "foo"
    ]
  },
  {
    "id": 319,
    "access_type": [
      "publish",
      "create"
    ],
    "users_groups": [
      "bar"
    ]
  },
  {
    "id": 320,
    "access_type": [
      "publish",
      "create"
    ],
    "users_groups": [
      "foo"
    ]
  },
  {
    "id": 320,
    "access_type": [
      "consume",
      "create"
    ],
    "users_groups": [
      "bar"
    ]
  }
]

您的预期输出是什么？@hek2mgl-我已将预期输出添加到原始问题中。提前感谢。
