Parsing JSON with Powershell's ConvertFrom-Json - arrays

Question

I am trying to parse this JSON using Powershell's ConvertFrom-Json feature, but it seems to truncate the data:
{
"MessagesMonitoring": {
"version": 1,
"description": "Message Description"
},
"data": {
"swindon": {
"totalMessages": 0,
"identifier": [
{
"name": "ET",
"staleCount": 4
},
{
"name": "ET_2",
"staleCount": 4
}
]
},
"Reading": {
"totalMessages": 0,
"identifier": [
{
"name": "J3",
"staleCount": 2
}
]
},
"Yanki": {
"totalMessages": 0,
"identifier": [
{
"name": "UT",
"staleCount": 4
},
{
"name": "UT_2",
"staleCount": 4
}
]
}
}
}
Request:
$request = 'http://localhost:8000/hi.json'
Invoke-WebRequest $request |
ConvertFrom-Json |
Select swindon
Response:
StatusCode : 200 StatusDescription : OK

"MessagesMonitoring": {
"version": 1,

"data": {

"identifier": [

Not sure what I may be doing incorrectly. Any advise/guidance on how to parse the JSON into this format would be great.
swindon|identifier|ET|4
swindon|totalMessages|0
swindon|identifier|ET2|4
Reading|identifier|J3|2
Reading|totalMessages|0
Yanki|identifier|UT|4
Yanki|identifier|U_T|4
Yanki|totalMessages|0

You are missing a step. The Content element of the response contains the JSON, so that's what you need to feed into ConvertFrom-Json:
$request = 'http://localhost:8000/hi.json'
$resp = $(Invoke-WebRequest $request).Content | ConvertFrom-Json
Then, within the JSON you have a dictionary, within which the "data" key contains the information I think you're interested in, access it using this syntax:
$resp.data
That should get you started
