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

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

  // 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.

  const json = new 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');

  const http = new 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.
  const sbResponse = new StringBuilder();
  try {
    await http.quickGetSbAsync('https://key_vault_name.vault.azure.net/certificates?api-version=7.4', sbResponse);
  } catch {

    const statusCode = http.lastStatus;
    if (statusCode === 0) {
      // We did not get a response from the server..
      console.log(http.lastErrorText);
    } else {
      // We received a response, but it was an error.
      console.log(`Error response status code: ${statusCode}`);
      console.log('Error response:');
      console.log(sbResponse.getAsString());
    }
