finalizeOrder method

Future<Order?> finalizeOrder(Order order, String csr, { int retries = 5, })

Will finalize the order by sending a POST request to the order's finalize url including the given csr in the payload. The given csr will be transformed in the necessary base64url encoding.

RFC : datatracker.ietf.org/doc/html/rfc8555#page-47 When attempting to finalize the order the CA may not immediately return the certificate. In this case we will wait 4 seconds and try again to fetch the certificate (url). This usually works on the first try but we allow you to set the retry limit via retries which defaults to 5.

Implementation

Future<Order?> finalizeOrder(Order order, String csr,
    {int retries = 5}) async {
  var transformedCsr = AcmeUtils.formatCsrBase64Url(csr);
  try {
    Order? persistent;
    var firstpass = true;
    Results results;
    do {
      if (firstpass) {
        results = await _finalizeOrder(order, transformedCsr);
      } else {
        results = await _retry(order, transformedCsr);
      }
      firstpass = false;
      retries--;

      /// the CA was stilling processing the order
    } while (results.response.data['status'] == 'processing' && retries > 0);

    if (results.response.data['status'] != 'valid') {
      persistent = null;
    } else {
      persistent = results.order;
    }
    return persistent;
  } on DioException catch (e) {
    print(e.response!.data!.toString());
  }
  return null;
}
