Azure Key Vault Get Certificates

See more Azure Key Vault Examples

Demonstrates how to list the certificates in an Azure Key Vault.

Note: This example requires Chilkat v9.5.0.96 or later.

Perl

use chilkat();

# 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 = chilkat::CkJsonObject->new();
$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 = chilkat::CkHttp->new();

# 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.
$http->put_AuthToken($json->emit());

# Replace key_vault_name with the name of your Azure Key Vault.
$sbResponse = chilkat::CkStringBuilder->new();
$success = $http->QuickGetSb("https://key_vault_name.vault.azure.net/certificates?api-version=7.4",$sbResponse);
if ($success == 0) {

    $statusCode = $http->get_LastStatus();
    if ($statusCode == 0) {
        # We did not get a response from the server..
        print $http->lastErrorText() . "\r\n";
    }
    else {
        # We received a response, but it was an error.
        print "Error response status code: " . $statusCode . "\r\n";
        print "Error response:" . "\r\n";
        print $sbResponse->getAsString() . "\r\n";
    }

    exit;
}

$jsonResp = chilkat::CkJsonObject->new();
$jsonResp->LoadSb($sbResponse);
$jsonResp->put_EmitCompact(0);
