消息推送ios用了apns，android用的是gcm。推送失败都会返回无效的token，但是无效的tokne中，能不能区分到哪些是禁止通知，哪些是卸载app导致的呢？
1 apns php 的推送返回错误处理
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['statusCode'] > 1 && $aError['statusCode'] <= 8) {
$this->_log("WARNING: Message ID {$k} {$sCustomIdentifier} has an unrecoverable error ({$aError['statusCode']}), removing from queue without retrying...");
$this->_removeMessageFromQueue($k, true);
continue 2;
}
}
if (($nErrors = count($aMessage['ERRORS'])) >= $this->_nSendRetryTimes) {
$this->_log(
"WARNING: Message ID {$k} {$sCustomIdentifier} has {$nErrors} errors, removing from queue..."
);
$this->_removeMessageFromQueue($k, true);
continue;
}
}通过禁止通知,apns不会报错，不会将这个token当成无效或错误的token。
卸载app，会调用到以下判断，statusCode等于8
if ($aError['statusCode'] > 1 && $aError['statusCode'] <= 8) {
$this->_log("WARNING: Message ID {$k} {$sCustomIdentifier} has an unrecoverable error ({$aError['statusCode']}), removing from queue without retrying...");
$this->_removeMessageFromQueue($k, true);
continue 2;
}因此，apns应该是可以区分卸载导致的推送失败，但是禁止通知则无法反应
2 GCM的错误判断代码分析：
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个方法都不会写入错误token，也就是说禁止通知，token也是有效的，且不会返回错误。
如果是卸载app，则会执行到getInvalidRegistrationIds，且$result['error']==NotRegistered
这样，GCM如果返回的是NotRegistered，则说明是卸载产生的错误信息，而禁止通知，GCM是当成正常token发出去的。
通过以上测试，说明apns和gcm对禁止通知都是当成正常token来处理的，而卸载app则会当成无效的token。（卸载后重装的话，会生成新的token）
