Wait and Retry logic to avoid RateExceedError in PHP

[faisal hossain]

Hi,

I am getting RateExceedError when tring to make large operations in one mutate request (1000 operations in 1 mutate call), the API expert suggests to honor the retryAfterSeconds=86400

Can anyone give me the example error handling code for PHP??

It's very urgent. Thanks in advance

Cheers

  public static function mutateEntities($adwords_user, $service_name, $ops){
    $service = $adwords_user->GetService($service_name, Utils::ADWORDS_VERSION);

    $opc = count($ops);
    if ($opc > 5000)
      throw new \Exception('Too many operations for ' . $service_name);

    for ($iii = 0; $iii < 5; $iii++){
      RateLimiter::throttle($adwords_user->getClientCustomerId(), $opc);
      try {
        $service->mutate($ops);
        break;
      } catch (\Exception $e){
        $errors = ( ($e instanceof \SoapFault) ? \ErrorUtils::GetApiErrors($e) : null);
        if (!Utils::isRetriable($errors))
          throw new NonRetriableException('Non-retriable error: ' . $e->getMessage()); // here I just check if the error seems to be due to a bad request and if so, do not retry
        RateLimiter::reportError($adwords_user->getClientCustomerId(), $iii, $errors);
      }
      if ($iii + 1 == 5){
        throw new \Exception('Adwords query failed after max retries. ' . $e->getMessage());
      }
    }

  }

RateLimiter:

  public static function reportError($account, $attemptNum, $errors = null){
    if (!$account)
      $account = self::NO_ACCOUNT;

    // determine if it is a rate limit issue
    $error_types = [];
    $rateScope = $rateName = null;
    if ($errors)
      foreach ($errors as $i){
        @$error_types[ $i->ApiErrorType ]++;
        if ($i->ApiErrorType == 'RateExceededError')
          list($rateScope, $rateName) = array($i->rateScope, $i->rateName);
      }

    error_log('AdwordsRateLimiter error ' . $account . ' ' . $rateScope . ' ' . $rateName . ' ' . ($rateScope ? 'RATE LIMIT EXCEEDED' : '') . '; ' . json_encode($error_types) );

    if ($rateScope && $rateName){
      $data = array('account' => $account, 'err' => '1', 'attemptNum' => $attemptNum, 'rateScope' => $rateScope, 'rateName' => $rateName);
    } else {
      $data = array('account' => $account, 'err' => '1', 'attemptNum' => $attemptNum);
    }
    // log $data: self::sendRequest($data);
  }

^^ Here is some code we use for handling errors. While I don't check for retryAfterSeconds, hopefully you can see where that field might be in the error objects.

Hope it helps.

Thanks,

Many many...thanks @Kristopher for your reply, That someone is me :) on the other thread.I wish your logic and given code will help me out from this problem.

Thanks Again
