Authentication in Powershell to update PowerBI dataset.

[mcguija]

Hi,

Here is my working code to update a dataset:

# This sample script calls the Power BI API to progammtically trigger a refresh for the dataset
# It then calls the Power BI API to progammatically to get the refresh history for that dataset
# For full documentation on the REST APIs, see:
# https://msdn.microsoft.com/en-us/library/mt203551.aspx 

# Instructions:
# 1. Install PowerShell (https://msdn.microsoft.com/en-us/powershell/scripting/setup/installing-windows-powershell) and the Azure PowerShell cmdlets (https://aka.ms/webpi-azps)
# 2. Set up a dataset for refresh in the Power BI service - make sure that the dataset can be 
# updated successfully
# 3. Fill in the parameters below
# 4. Run the PowerShell script

# Parameters - fill these in before running the script!
# =====================================================

# An easy way to get group and dataset ID is to go to dataset settings and click on the dataset
# that you'd like to refresh. Once you do, the URL in the address bar will show the group ID and 
# dataset ID, in the format: 
# app.powerbi.com/groups/{groupID}/settings/datasets/{datasetID} 

$groupID = "me" # the ID of the group that hosts the dataset. Use "me" if this is your My Workspace
$datasetID = "d234581a-734c-473c-be6c-e72f54ff9058" # the ID of the dataset that hosts the dataset

# AAD Client ID
# To get this, go to the following page and follow the steps to provision an app
# https://dev.powerbi.com/apps
# To get the sample to work, ensure that you have the following fields:
# App Type: Native app
# Redirect URL: urn:ietf:wg:oauth:2.0:oob
#  Level of access: all dataset APIs
$clientId = "fbeb6bda-74a4-4a51-9c92-38a22c172a49" 

# End Parameters =======================================

# Calls the Active Directory Authentication Library (ADAL) to authenticate against AAD
function GetAuthToken
{
       $adal = "C:\Program Files\On-premises data gateway\Microsoft.IdentityModel.Clients.ActiveDirectory.dll"
 
       $adalforms = "C:\Program Files\On-premises data gateway\Microsoft.IdentityModel.Clients.ActiveDirectory.WindowsForms.dll"
 
       [System.Reflection.Assembly]::LoadFrom($adal) | Out-Null
 
       [System.Reflection.Assembly]::LoadFrom($adalforms) | Out-Null
 
       $redirectUri = "urn:ietf:wg:oauth:2.0:oob"
 
       $resourceAppIdURI = "https://analysis.windows.net/powerbi/api"
 
       $authority = "https://login.microsoftonline.com/common/oauth2/authorize";
 
       $authContext = New-Object "Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext" -ArgumentList $authority
 
       $authResult = $authContext.AcquireToken($resourceAppIdURI, $clientId, $redirectUri, "Auto")
 
       return $authResult
}

# Get the auth token from AAD
$token = GetAuthToken

# Building Rest API header with authorization token
$authHeader = @{
   'Content-Type'='application/json'
   'Authorization'=$token.CreateAuthorizationHeader()
}

# properly format groups path
$groupsPath = ""
if ($groupID -eq "me") {
    $groupsPath = "myorg"
} else {
    $groupsPath = "myorg/groups/$groupID"
}

# Refresh the dataset
$uri = "https://api.powerbi.com/v1.0/$groupsPath/datasets/$datasetID/refreshes"
Invoke-RestMethod -Uri $uri –Headers $authHeader –Method POST –Verbose

# Check the refresh history
$uri = "https://api.powerbi.com/v1.0/$groupsPath/datasets/$datasetID/refreshes"
Invoke-RestMethod -Uri $uri –Headers $authHeader –Method GET –Verbose

Only issue is I get prompted to login, twice!

 

Is there some code I can add to my above powershell script to bypass these userid prompts?  Where exactly would that code be inserted into my code?

Thanks

Jason

Actually can someone let me know how i I can pass the password encriped to the powershell script?  Hard now the working copy is hardcoded
