Upload file to Jenkins through HTTP Request

Question

I have a Jenkins Job that requires a file as parameter (I'm using the file parameter plugin). When I made the call to Jenkins I notice that the file parameter doesn't get sent but the other parameters do (CHOICE and string), what I'm doing wrong?

$credPair = "user:token";
$encodedCredentials = [Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($credPair));
$headers = @{
    "Authorization" = "Basic $encodedCredentials";
    "Content-Type" = "multipart/form-data";
}

$choiceParam = "option"
$stringParam = "value"
$file = "file_path"
$Body = @{ "File" = [IO.File]::ReadAllText($file); }

$url = "https://server/job/buildWithParameters?CHOICE=" + $choiceParam + '&string' + $stringParam

try {
    Invoke-RestMethod -Uri $url -Headers $headers -Method Post -Body $Body
}
catch {
    Write-Host "StatusCode: " $_.Exception.Response.StatusCode.value__
    Write-Host "StatusDescription: " $_.Exception.Response.StatusDescription
    write-host "Error details: " $_.ErrorDetails.Message
    exit
}

@zett42 I solve it, apparently only in the form you put the file, the others params are put in the url

$credPair = "user:token";
$encodedCredentials = [Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($credPair));
$headers = @{
    "Authorization" = "Basic $encodedCredentials";
}

$choiceParam = "option"
$stringParam = "value"
$file = "file_path"

$form = @{
    INSERT_NAME_OF_FILE_PARAM = Get-Item $file
}

$url = "https://server/job/INSERT_JOBNAME/buildWithParameters?INSERT_NAME_OF_CHOICE_PARAM=" + $choiceParam + '&INSERT_NAME_OF_STRING_PARAM=' + $stringParam

try {
    Invoke-RestMethod -Uri $url -Headers $headers -Method Post -Form $form
}
catch {
    Write-Host "StatusCode: " $_.Exception.Response.StatusCode.value__
    Write-Host "StatusDescription: " $_.Exception.Response.StatusDescription
    write-host "Error details: " $_.ErrorDetails.Message
    exit
}
