How to use maxresult and nextmarker parameter in Azure File Share List REST API - azure

Question

I am trying to list all the shares present in Storage Account using List Share REST API (https://learn.microsoft.com/en-us/rest/api/storageservices/list-shares#Authorization). but I am having issues with Authorization header with marker parameter. I guess problem is with $stringtosign variable under $nextmarker If Statement.
$StorageAccount = "XXXXX"
$Accesskey = "XXXXXXX==";
$Version="2019-12-12"
$SharePropObj = #()
$date = [System.DateTime]::UtcNow.ToString("R",[Globalization.CultureInfo]::InvariantCulture)
$stringToSign = "GET`n`n`n`n`n`n`n`n`n`n`n`n"+
"x-ms-date:$date`nx-ms-version:$version`n" +
"/$storageAccount/`ncomp:list`nmaxresults:5000"
$hmacsha = New-Object System.Security.Cryptography.HMACSHA256
$hmacsha.key = [Convert]::FromBase64String($accesskey)
$signature = $hmacsha.ComputeHash([Text.Encoding]::UTF8.GetBytes($stringToSign))
$signature = [Convert]::ToBase64String($signature)
$headers=#{"x-ms-date"=$date;
"x-ms-version"= $version;
"Authorization"= "SharedKey $($storageAccount):$signature";
"ContentType"="application/xml"
}
$URI = "https://$storageAccount.file.core.windows.net/?comp=list&maxresults=5000"
Try {
$response = Invoke-RestMethod $URI -Method 'GET' -Headers $headers
}Catch {
"Error Occurred. $_.exception.message"
}
If ($response){
[xml]$Result = [xml]($response -replace '',"")
$Shareprops = $Result.EnumerationResults.ChildNodes.share | %{
$share = $_.Name
$Quota = $_.properties.Quota
"$share,$Quota"
}
$SharePropCol = "ShareName,Quota"
$SharePropObj += #($SharePropCol,($Shareprops | where {$_.length -gt 1})) | ConvertFrom-Csv -Delimiter ","
$SharePropObj
$NextMarker = $Result.EnumerationResults.NextMarker.Split("/")[-1]
if ($NextMarker){
#Write-Error "Data for some shares are missed"
#$SharePropObj = #()
$date = [System.DateTime]::UtcNow.ToString("R",[Globalization.CultureInfo]::InvariantCulture)
$stringToSign = "GET`n`n`n`n`n`n`n`n`n`n`n`n"+
"x-ms-date:$date`nx-ms-version:$version`n" +
"/$storageAccount/`ncomp:list`nmaxresults:5000`nmarker:$NextMarker"
$hmacsha = New-Object System.Security.Cryptography.HMACSHA256
$hmacsha.key = [Convert]::FromBase64String($accesskey)
$signature = $hmacsha.ComputeHash([Text.Encoding]::UTF8.GetBytes($stringToSign))
$signature = [Convert]::ToBase64String($signature)
$headers=#{"x-ms-date"=$date;
"x-ms-version"= $version;
"Authorization"= "SharedKey $($storageAccount):$signature";
"ContentType"="application/xml"
}
$URI = "https://$storageAccount.file.core.windows.net/?comp=list&maxresults=5000&marker=$NextMarker"
$response1 = Invoke-RestMethod $URI -Method 'GET' -Headers $headers
[xml]$Result = [xml]($response1 -replace '',"")
$Shareprops = $Result.EnumerationResults.ChildNodes.share | %{
$share = $_.Name
$Quota = $_.properties.Quota
"$share,$Quota"
}
$SharePropCol = "ShareName,Quota"
$SharePropObj += #($SharePropCol,($Shareprops | where {$_.length -gt 1})) | ConvertFrom-Csv -Delimiter ","
$SharePropObj
}
}

Please change the following code of yours:
1.for $NextMarker, please change this line of code
$NextMarker = $Result.EnumerationResults.NextMarker.Split("/")[-1]
to
$NextMarker = "/$storageAccount/" + $Result.EnumerationResults.NextMarker.Split("/")[-1]
in the if ($NextMarker){} code block -> for the $stringToSign, please place the marker:$NextMarker prior to maxresults:5000. Change it like below:
$stringToSign = "GET`n`n`n`n`n`n`n`n`n`n`n`n"+
"x-ms-date:$date`nx-ms-version:$version`n" +
"/$storageAccount/`ncomp:list`nmarker:$NextMarker`nmaxresults:5000".
3.in the if ($NextMarker){} code block -> for $URI, please also place the marker=$NextMarker prior to maxresults=5000. Change it like below:
$URI = "https://$storageAccount.file.core.windows.net/?comp=list&marker=$NextMarker&maxresults=5000"
I have tested it and it works fine. Please let me know if you still have the issue.
