使用 PowerShell 解析 json

Question

我尝试从 check_mk with http-api "action=get_all_hosts" 获取我所有的主机响应是 json 格式，看起来像这样：

"{"result": {"some host name": {"attributes": {"tag_Chassis": "Vm", "tag_ServerFamily": "WindowsServer", "tag_criticality": "prod", "tag_Application": "AllApp", "alias": "some alias", "ipaddress": "172.21.x.x", "tag_networking": "lan"}, "hostname": "some host name", "path": "windows"}}"

现在我尝试格式化响应但没有成功。如何将结果格式化为具有所有属性的 table？

Answer 1

您粘贴的 JSON 不正确。它不应该在开头或结尾有引号。最后还漏了一个 }。您可以使用任何在线工具验证它 like this.

一旦你有了正确的 JSON 应该是：

{"result": {"some host name": {"attributes": {"tag_Chassis": "Vm", "tag_ServerFamily": "WindowsServer", "tag_criticality": "prod", "tag_Application": "AllApp", "alias": "some alias", "ipaddress": "172.21.x.x", "tag_networking": "lan"}, "hostname": "some host name", "path": "windows"}}}

您可以在从 JSON:

转换属性后访问它们

# Convert and save to variable
$convertedJSON = @"
{"result": {"some host name": {"attributes": {"tag_Chassis": "Vm", "tag_ServerFamily": "WindowsServer", "tag_criticality": "prod", "tag_Application": "AllApp", "alias": "some alias", "ipaddress": "172.21.x.x", "tag_networking": "lan"}, "hostname": "some host name", "path": "windows"}}}
"@ | ConvertFrom-Json

# Access attributes
$convertedJSON.result.'some host name'.attributes

# If you don't know the hostname you can find it like this
($convertedJSON.result |Get-Member | ? MemberType -eq "NoteProperty").Name

# List all attributes from your JSON
$convertedJSON.result.$(($convertedJSON.result |Get-Member | ? MemberType -eq "NoteProperty").Name).attributes

# Output will be like this
tag_Chassis      : Vm
tag_ServerFamily : WindowsServer
tag_criticality  : prod
tag_Application  : AllApp
alias            : some alias
ipaddress        : 172.21.x.x
tag_networking   : lan
