推播訊息能不能區分禁止通知和卸載兩種類型?

訊息推播ios用了apns，android用的是gcm。推播失敗都會回傳無效的token，但是無效的tokne中，能不能區分到哪些是禁止通知，哪些是卸載app導致的呢？ 

1 APNS PHP 的推播回傳錯誤處理 
Push.php 

if (!empty($aMessage['ERRORS'])) {
foreach($aMessage['ERRORS'] as $aError) {
if ($aError['statusCode'] == 0) {
$this->_log("INFO: Message ID {$k} {$sCustomIdentifier} has no error ({$aError['statusCode']}), removing from queue...");
$this->_removeMessageFromQueue($k);
continue 2;
} else if ($aError[&#39;statusCode&#39;] > 1 && $aError[&#39;statusCode&#39;] <= 8) {
$this->_log("WARNING: Message ID {$k} {$sCustomIdentifier} has an unrecoverable error ({$aError[&#39;statusCode&#39;]}), removing from queue without retrying...");
$this->_removeMessageFromQueue($k, true);
continue 2;
}
}
if (($nErrors = count($aMessage[&#39;ERRORS&#39;])) >= $this->_nSendRetryTimes) {
$this->_log(
"WARNING: Message ID {$k} {$sCustomIdentifier} has {$nErrors} errors, removing from queue..."
);
$this->_removeMessageFromQueue($k, true);
continue;
}
}

透過禁止通知,apns不會報錯，不會將這個token當成無效或錯誤的token。

卸載app，會呼叫到以下判斷，statusCode等於8 

 if ($aError[&#39;statusCode&#39;] > 1 && $aError[&#39;statusCode&#39;] <= 8) {
$this->_log("WARNING: Message ID {$k} {$sCustomIdentifier} has an unrecoverable error ({$aError[&#39;statusCode&#39;]}), removing from queue without retrying...");
$this->_removeMessageFromQueue($k, true);
continue 2;
}

因此，apns應該是可以區分卸載導致的推送失敗，但是禁止通知則無法反應 

2 GCM的錯誤判斷代碼分析： 
Response.class .php 

/**
     * Returns an array containing invalid registration ids
     * They must be removed from DB because the application was uninstalled from the device.
     *
     * @return array
     */
    public function getInvalidRegistrationIds()
    {
        if ($this->getFailureCount() == 0) {
            return array();
        }
        $filteredResults = array_filter($this->results,
            function($result) {
                return (isset($result['error']) 
                && (($result['error'] == "NotRegistered")  || ($result['error'] == "InvalidRegistration")));
            });
        return array_keys($filteredResults);
    }
    /**
     * Returns an array of registration ids for which you must resend a message (?),
     * cause devices aren't available now.
     *
     * @TODO: check if it be auto sended later
     *
     * @return array
     */
    public function getUnavailableRegistrationIds()
    {
        if ($this->getFailureCount() == 0) {
            return array();
        }
        $filteredResults = array_filter($this->results,
            function($result) {
                return (
                    isset($result['error'])
                    &&
                    ($result['error'] == "Unavailable")
                    );
            });
        return array_keys($filteredResults);
    }

如果禁止通知，上述2個方法都不會寫入錯誤token，也就是說禁止通知，token也是有效的，且不會回傳錯誤。
如果是卸載app，則會執行到getInvalidRegistrationIds，且$result['error']==NotRegistered 

這樣，GCM如果返回的是NotRegistered，則說明是卸載產生的錯誤訊息，而禁止通知，GCM是當成正常token發出去的。 


通過以上測試，說明apns和gcm對禁止通知都是當成正常token來處理的，而卸載app則會當成無效的token。 （卸載後重裝的話，會產生新的token）
