Cannot parse url string for Microsoft graph because using the Invoke-MSGraphRequest command and quer-CodePudding

I cannot parse and make a call using the current URL because when I use the $filter and $select query parameters it breaks the string, yet it works great in Postman and give me all the data I needed.

Connect-MSGraph
Invoke-MSGraphRequest -Url "https://graph.microsoft.com/beta/deviceManagement/managedDevices?$select=emailaddress,id,imei,operatingSystem,ownerType,managedDeviceOwnerType&$filter=(operatingSystem eq 'iOS')" -HttpMethod GET

I need to filter these devices then if the ownership is personal, I was going to use graph API again to Update the object device using PATCH. Please help with this

CodePudding user response：

The immediate solution to your problem is to simply escape the verbatim $'s with a backtick `:

Invoke-MSGraphRequest -Url "https://graph.microsoft.com/beta/deviceManagement/managedDevices?`$select=emailaddress,id,imei,operatingSystem,ownerType,managedDeviceOwnerType&`$filter=(operatingSystem eq 'iOS')" -HttpMethod GET

Or to use single-quotes ' to avoid PowerShell attempting to expand what looks like variables - literal single-quotes inside the URL will have to be escaped by doubling them:

Invoke-MSGraphRequest -Url 'https://graph.microsoft.com/beta/deviceManagement/managedDevices?$select=emailaddress,id,imei,operatingSystem,ownerType,managedDeviceOwnerType&$filter=(operatingSystem eq ''iOS'')' -HttpMethod GET

That being said, I'd personally recommend constructing the query parameters from simpler parts:

$endpointURL = 'https://graph.microsoft.com/beta/deviceManagement/managedDevices'

# assign variable parts of the filter to a variable
$targetOperatingSystem = 'iOS'

# construct a hashtable containing all the query parameters
$GraphParameters = [ordered]@{
  '$select' = 'emailaddress,id,imei,operatingSystem,ownerType,managedDeviceOwnerType'
  '$filter' = "(operatingSystem eq '$targetOperatingSystem')"
}

# construct query string and final URL from the individual parts above
$queryString = $GraphParameters.GetEnumerator().ForEach({ $_.Key,$_.Value -join '=' }) -join '&'
$URL = $endpointURL,$queryString -join '?'

And then finally invoke Invoke-MSGraphRequest -Url $URL -HttpMethod Get
