# This requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# We demonstrated how to get an access token for your Azure Key Vault
# in this example: Azure Key Vault Get OAuth2 Access Token using Client Credentials

# However.. starting in Chilkat v9.5.0.96, instead of directly providing Chilkat with the OAuth2 access token,
# you can instead provide the means for Chilkat to automatically get the OAuth2 access token,
# and in addition, Chilkat will automatically re-fetch a new OAuth2 access token as needed, such as shortly 
# prior to or after expiration.

# You do this by setting the AuthToken property to a JSON string that contains the required information.

$json = New-Object Chilkat.JsonObject
$json.UpdateString("client_id","APP_ID")

# The APP_PASSWORD is the "password" returned by the Azure CLI command: az ad sp create-for-rbac --name http://example.com --role Contributor
# See Azure Key Vault Get OAuth2 Access Token using Client Credentials
$json.UpdateString("client_secret","APP_PASSWORD")

# The access token will be for Azure Key Vault operations.
$json.UpdateString("resource","https://vault.azure.net")

# Specify the token endpoint which includes your tenant ID.
$json.UpdateString("token_endpoint","https://login.microsoftonline.com/TENANT_ID/oauth2/token")

$http = New-Object Chilkat.Http

# Instead of providing an actual access token, we give Chilkat the information that allows it to 
# automatically fetch the access token using the OAuth2 client credentials flow.
$http.AuthToken = $json.Emit()

# Replace key_vault_name with the name of your Azure Key Vault.
$sbResponse = New-Object Chilkat.StringBuilder
$success = $http.QuickGetSb("https://key_vault_name.vault.azure.net/certificates?api-version=7.4",$sbResponse)
if ($success -eq $false) {

    $statusCode = $http.LastStatus
    if ($statusCode -eq 0) {
        # We did not get a response from the server..
        $($http.LastErrorText)
    }
    else {
        # We received a response, but it was an error.
        $("Error response status code: " + $statusCode)
        $("Error response:")
        $($sbResponse.GetAsString())
    }
