display Json nested arrays in powershell - json

Question

I've written one JSON script with nested arrays and trying to display the all the data based on title. but unfortunately i couldn't make that happen. i'm placing my JSON and powershell code below. kindly help me.
JSON code:
{
"Deploy": {
"ENV": "DIT",
"Servers": [
{
"Webservers": [
{
"Server": ["Server1","Server2"],
"site": ["website1","WebSite2"],
"VDIR": ["WebSite1","WebSite2"]
},
{
"Server": ["Server1","Server2"],
"site": ["WebSite1","WebSite2"],
"VDIR": ["WebSite1","WebSite2"]
}
]
},
{
"Winservers": [
{
"Server": ["Server1","Server2"],
"winService": ["service1","service2"]
},
{
"Server": ["Server3","Server4"],
"winService": ["service3","service4"]
}
]
}
]
}
}
Powershell Code:
$Deploy=(Get-Content D:\Deploy.json -Raw) -join "`n"|ConvertFrom-Json
foreach($i in $Deploy.Deploy.Servers) {
$s=($i | Get-Member -MemberType *property).Name
Write-host "$s" -ForegroundColor Yellow
foreach($j in $s) {
$items=($i.$j|Get-Member -MemberType *property).Name
Write-host "$items" -ForegroundColor Yellow
foreach($k in $items) {
$z=($j.$k | Get-Member -MemberType *property).Name
Write-host "$z" -ForegroundColor Yellow
}
}
}
Current result is :
Webservers
Server site VDIR
Winservers
Server winService
But expected result should be like below:
Webservers:
Server: Sites: VDIR:
list of servers list of sites list of VDIR
Server: Sites: VDIR:
list of servers list of sites list of VDIR
Winservers:
Server: services:
list of servers list of sites
Kindly help ... i'm trying by best in different ways but none of one gave expected result.

Answer 1

OK. I think your problem can be solved with next way.
$ht, $src = #{}, 'D:\sandbox\source.xml'
($srv = (Get-Content $src | ConvertFrom-Json).Deploy.Servers).ForEach{
$name = $_.PSObject.Properties.Name
$ht[$name] = $srv.$name
}
Write-Host Webservers -ForegroundColor Yellow
$ht.Webservers | Out-String
Write-Host Winservers -ForegroundColor Yellow
$ht.Winservers | Out-String

If what you want to achieve is just a formatted output, maybe this is more to your liking
$deploy = Get-Content 'D:\Deploy.json' -Raw | ConvertFrom-Json
Write-Host "Webservers:`r`n-----------"
$items = #()
foreach ($server in $deploy.Deploy.Servers.Webservers) {
foreach ($item in $server) {
$items += New-Object -TypeName PSObject -Property ([ordered]#{
Server = #($item.Server) -join ', '
Sites = #($item.site) -join ', '
VDIR = #($item.VDIR) -join ', '
})
}
}
$items | Out-String
Write-Host "Winservers:`r`n-----------"
$items = #()
foreach ($server in $deploy.Deploy.Servers.Winservers) {
foreach ($item in $server) {
$items += New-Object -TypeName PSObject -Property ([ordered]#{
Server = #($item.Server) -join ', '
WinService = #($item.winService) -join ', '
})
}
}
$items | Out-String
The output will look like this:
Webservers:
-----------
Server Sites VDIR
------ ----- ----
Server1, Server2 website1, WebSite2 WebSite1, WebSite2
Server1, Server2 WebSite1, WebSite2 WebSite1, WebSite2
Winservers:
-----------
Server WinService
------ ----------
Server1, Server2 service1, service2
Server3, Server4 service3, service4

Answer 3

A pragmatic for-display-only solution that doesn't output the exact format you describe, but is concise (PSv3+):
(Get-Content -Raw D:\Deploy.json | ConvertFrom-Json).Deploy.Servers |
ForEach-Object {
$serverTypePropName = $_.psobject.properties.Name
Write-Host "${serverTypePropName}:"
$_.$serverTypePropName | Format-Table
}
(Get-Content -Raw D:\Deploy.json | ConvertFrom-Json) converts the JSON input to custom objects.
.Deploy.Server accesses the array-valued property whose elements are the objects whose Webservers and Winservers properties, respectively, contain the server-details sub-arrays.
In the ForEach-Object script block:
$_.psobject.properties.Name extracts the name of the one property (Webservers or Winservers) of each input object that contains the array of server details.
$_.$serverTypePropName | Format-Table accesses that property and renders the server-details array as a table.
Note that explicit use of Format-Table is needed, because the server-detail arrays have different property structures between the Webservers and the Winservers object; without an explicit formatting/output command, only the first array's properties would render.
With your sample input, the above yields:
Webservers:
Server site VDIR
------ ---- ----
{Server1, Server2} {website1, WebSite2} {WebSite1, WebSite2}
{Server1, Server2} {WebSite1, WebSite2} {WebSite1, WebSite2}
Winservers:
Server winService
------ ----------
{Server1, Server2} {service1, service2}
{Server3, Server4} {service3, service4}
