在一定条件下提取json thoweh poweshell的每个值

Question

我需要检查是否全部都在内核，certmgr，zipzoom等中。[[change_flag为TRUE，并且unpack也为真，而不是每个获取第一个对象的name，即zipzoom，获取extension，即.jar，获取文件信息，即每个文件名，其本地路径和文件路径。

对于具有前面提到的前提条件的内核，cermgr，activemq依此类推，即

change_flag

为TRUE，并且如果unpack也为TRUE

[
  {
    "name": "kernel",
    "change_flag": "FALSE",
    "unpack": "FALSE",
    "extension": "jar",
    "fileinfo": [
      {
        "localPath": "Local path",
        "fileName": "kernel.jar",
        "filePath": "setupfiles\\controlroom"
      }
    ]
  },
  {
    "name": "activemq",
    "change_flag": "FALSE",
    "unpack": "FALSE",
    "extension": "jar",
    "fileinfo": [
      {
        "localPath": "Local path",
        "fileName": "activemq.jar",
        "filePath": "setupfiles\\controlroom"
      }
    ]
  },
  {
    "name": "certmgr",
    "change_flag": "FALSE",
    "unpack": "FALSE",
    "extension": "jar",
    "fileinfo": [
      {
        "localPath": "Local path",
        "fileName": "certmgr.jar",
        "filePath": "setupfiles\\controlroom"
      }
    ]
  },
  {
    "name": "zipzoom",
    "extension": "jar",
    "change_flag": "TRUE",
    "unpack": "TRUE",
    "fileinfo": [
      {
        "localPath": "Local path",
        "fileName": "zipzoom.jar",
        "filePath": "destpath1"
      },
      {
        "localPath": "Local path",
        "fileName": "localpath2\\file2",
        "filePath": "destpath2\\"
      }
    ]
  }
]

由于这是JSON，因此可以使用ConvertFrom-Json cmdlet将其转换为PSObjects数组，并使用Where-Object子句来过滤所需的对象：
