我们的数据库中有大约 900 个用于 GCM 推送通知的 Android 设备令牌。
我使用这个 PHP 函数将推送指令发送到 GCM 服务器:
function send_android_push($android_gcm_reg_ids, $title, $message, $activityToLaunch) {
global $ANDROID_GCM_API_KEY, $TESTING, $TEST_ANDROID_DEVICE_REG_ID;
if ($TESTING) {
$android_gcm_reg_ids = [
$TEST_ANDROID_DEVICE_REG_ID
];
}
$url = "https://android.googleapis.com/gcm/send";
$data = array(
"title" => $title,
"message" => $message,
"activityToLaunch" => $activityToLaunch,
);
$post = array(
'registration_ids' => $android_gcm_reg_ids,
'data' => $data
);
$headers = array(
'Authorization: key=' . $ANDROID_GCM_API_KEY,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($post));
$result = curl_exec($ch);
if (curl_errno($ch)) {
$result .= "<br />GCM error: " . curl_error($ch);
}
curl_close($ch);
return $result;
}
以下是该函数/GCM 返回的 JSON 内容片段:
{
"multicast_id":5609284883833846123,
"success":493,
"failure":401,
"canonical_ids":20,

{

},
{
"error":"NotRegistered"
},
{

},
etc., etc.
似乎是说我的数据库中有设备令牌,NotRegistered
但是正如您所见,它没有告诉我哪个设备令牌未注册,所以我想知道如何在我的数据库中将其标记为过时?
I thought that maybe the elements of the JSON array returned by the GCM server might correspond to the $android_gcm_reg_ids
array I pass into my send_android_push(...)
function but that can't be the case because the BPA91bHP29l2j6NPOldcpAvJCJBGk8oQFErfwuh93cxF8ajJJqBlVGqFcxMDEAc2LL2GKwmP86of49UgBTMycB5IdYergWRBETDNUrnzXX_55FgstCZiauPeD7MokIIPOFoOyW9vCRiBqZhlzLCuSnJ1ENFYtIh_PQ registration_id
appears numerous times in the GCM JSON array - despite that same token only在我的数据库中出现一次。
所以大概必须有其他方法从我的数据库中删除过时的设备令牌?
我担心这一点的原因是因为我之前遇到过这种情况(使用 iOS),发送错误的设备令牌(到 APNS)导致推送通知没有发送到有效设备,我显然想保留我的数据库反正状态不错。
我在网上找不到任何可以帮助的东西,所以也许我遗漏了一些明显的东西或弄错了?
