我有一个从API中提取的JSON对象，我需要从中提取IP地址。
数据存储在一个变量中，如下所示：
echo $IPMIAddr
count next previous results
----- ---- -------- -------
1 {@{id=17247; family=4; address=10.2.63.142/24; vrf=; tenant=; status=; role=; interface=; description=; ...
我可以使用点来解析数据以达到所需的效果
echo $IPMIAddr.results
id : 17247
family : 4
address : 10.2.63.142/24
vrf :
tenant :
status : @{value=1; label=Active}
role :
interface : @{id=50554;
url=http://netbox/api/dcim/interfaces/50554/; device=;
virtual_machine=; name=IPMI}
description :
nat_inside :
nat_outside :
custom_fields :
created : 2018-05-03
last_updated : 2018-05-03T08:08:36.856098Z
因此下一个逻辑步骤将是：
echo $IPMIAddr.results.address
但是当我这样做时，我得到了错误：
OverloadDefinitions
-------------------
System.Object&, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 Address(int )
因为.address是PowerShell中的预定义函数。
我该如何克服？
编辑：
结果：
Get-Member -InputObject $IPMIAddr
是
TypeName: System.Management.Automation.PSCustomObject
Name MemberType Definition
---- ---------- ----------
Equals Method bool Equals(System.Object obj)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
ToString Method string ToString()
count NoteProperty int count=1
next NoteProperty object next=null
previous NoteProperty object previous=null
results NoteProperty Object[] results=System.Object[]
和
Get-Member -InputObject $IPMIAddr.results
TypeName: System.Object[]
Name MemberType Definition

答案 0 :(得分：1)
看起来您的.results成员实际上是一个数组，其中包含一个名为Address的成员。您需要索引到数组中以访问适当的成员：
$IPMIaddr.results[0].address
ForEach-Object起作用的原因是由于枚举：
$IPMIaddr.results | Foreach-Object -MemberName address
这会将address成员拉离所有results对象。
