如何使用PowerShell从ExchangeOnline命令执行中获得JSON输出

我想执行ExchangeOnline命令，并通过 Select 某些属性将其转换为JSON，所有这些都在单个命令中完成！

例如，我的命令要 for each SharedMailbox获取RecipientPermissions，其输出为:

// command

Get-EXOMailbox -RecipientTypeDetails "SharedMailbox" -ResultSize unlimited | foreach { Get-EXORecipientPermission -Identity $_.Identity } 

上述命令样例输出为

 Identity          : testexosv
 Trustee           : NT AUTHORITY\SELF
 AccessControlType : Allow
 AccessRights      : {SendAs}
 IsInherited       : False
 InheritanceType   : All

 Identity          : SMBP
 Trustee           : 2b33e774737b4da26c2e551c00f
 AccessControlType : Allow
 AccessRights      : {SendAs}
 IsInherited       : False
 InheritanceType   : None

首先，我想将上述输出转换为JSON.因此，如果我简单地将其传递到ConvertTo-Json，则AccessRights的值将丢失如下:

 [
     {
       "Identity": "SMBP",
       "Trustee": "2b33e774737b4da26c2e551c00f",
       "AccessControlType": "Allow",
       "AccessRights": [
              1
        ],
       "IsInherited": false,
       "InheritanceType": "None"
     },
     {
       "Identity": "testexosv",
       "Trustee": "NT AUTHORITY\\SELF",
       "AccessControlType": "Allow",
       "AccessRights": [
          1
        ],
       "IsInherited": false,
       "InheritanceType": "All"
     }
  ]

其次，我只想在结果中 Select 特定的属性，例如:Identity, Trustee, AccessRights，将它们重命名为任意键，并且仍然保持Json struct .所以我实际上想要的O/P是:

 [
     {
       "ShareMailbox": "SMBP",
       "UPN": "2b33e774737b4da26c2e551c00f",  
       "Roles": [
              "SendAs"
        ]
     },
     {
       "SharedMailbox": "testexosv",
       "UPN": "NT AUTHORITY\\SELF",
       "Roles": [
          "SendAs"
        ]
     }
  ]

我试过以下命令:

 Get-EXOMailbox -RecipientTypeDetails "SharedMailbox" -ResultSize unlimited 
 | foreach { Get-EXORecipientPermission -Identity $_.Identity 
 | foreach {$_.Identity, $_.Trustee, [String]$_.AccessRights } | ConvertTo-Json} 

但它只提供JSON数组，而不是JSON对象.上述命令的输出为

 [
   "SMBP",
   "2b33e774737b4da26c2e551c00f",
   "SendAs"
 ]
 [
   "testexosv",
   "NT AUTHORITY\\SELF",
   "SendAs"
  ]
