Upload file with Powershell - powershell

Question

I'm trying to create a command in Powershell that is an equivalent of
curl -u username:abcd -i -F name=files -F filedata=#employees.csv https://myservice.com/v1/employees/csv
I need to have file name in the request. So in Powershell
$FilePath = 'employees.csv'
$FieldName = 'employees.csv'
$ContentType = 'text/csv'
$username = "user"
$password = "..."
$FileStream = [System.IO.FileStream]::new($filePath, [System.IO.FileMode]::Open)
$FileHeader = [System.Net.Http.Headers.ContentDispositionHeaderValue]::new('form-data')
$FileHeader.Name = $FieldName
$FileHeader.FileName = Split-Path -leaf $FilePath
$FileContent = [System.Net.Http.StreamContent]::new($FileStream)
$FileContent.Headers.ContentDisposition = $FileHeader
$FileContent.Headers.ContentType = [System.Net.Http.Headers.MediaTypeHeaderValue]::Parse($ContentType)
$MultipartContent = [System.Net.Http.MultipartFormDataContent]::new()
$MultipartContent.Add($FileContent)
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes("$($username):$($password)" ))
$Response = Invoke-WebRequest -Headers #{Authorization = "Basic $base64AuthInfo" } -Body $MultipartContent -Method 'POST' -Uri 'https://myservice.com/v1/employees/csv'
Is there a better (shorter) way of doing this so I have a file name in Content Disposition?
$body = get-content employees.csv -raw
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes("user:pass" ))
Invoke-RestMethod -Headers #{Authorization = "Basic $base64AuthInfo" } -uri url -Method Post -body $body -ContentType 'text/csv
# a flag -ContentDispositionFileName would be great

Taking a guess with what your endpoint will accept, but here's an example of your curl request in powershell:
$u, $p = 'username', 'password'
$b64 = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes("${u}:$p"))
$invokerestmethodParams = #{
'Uri' = 'https://myservice.com/v1/employees/csv'
'Method' = 'POST'
'Headers' = #{ Authorization = "Basic $b64" }
'InFile' = 'C:\path\to\employees.csv'
'SessionVariable' = 's' # use $s to view content headers, etc.
}
$output = Invoke-RestMethod #invokerestmethodParams
