我有一个关于Google Cloud Messaging的问题…
我发送GCM到谷歌3注册ID,然后谷歌回复,注册ID的2已发送成功,一个没有,因为注册ID是错误的!
但是它没有告诉我哪个注册ID没有发送…
现在我的问题是:我如何解析Google GCM响应以获得未发送的注册ID ?谷歌是否有一个API或其他东西,让我可以给它"multicat_id",它告诉我哪个注册ID有问题?
任何帮助都将非常感激,我只是很困惑:)
这是基于顺序的:
假设你发送这个:
{ "collapse_key": "score_update",
"time_to_live": 108,
"delay_while_idle": true,
"data": {
"score": "4x8",
"time": "15:16.2342"
},
"registration_ids":["4", "8", "15", "16", "23", "42"]
}
并得到Google的响应:
{ "multicast_id": 216,
"success": 3,
"failure": 3,
"canonical_ids": 1,
"results": [
{ "message_id": "1:0408" },
{ "error": "Unavailable" },
{ "error": "InvalidRegistration" },
{ "message_id": "1:1516" },
{ "message_id": "1:2342", "registration_id": "32" },
{ "error": "NotRegistered"}
]
}
这意味着您发送的第3个注册ID(15)无效,第6个(42)未注册。
我是这样做的:
$gcm_result = $gcm->send_notification($registration_ids, $message);
$jsonArray = json_decode($gcm_result);
if(!empty($jsonArray->results)){
$remove_ids = array();
for($i=0; $i<count($jsonArray->results);$i++){
if(isset($jsonArray->results[$i]->error)){
if($jsonArray->results[$i]->error == "NotRegistered"){
$remove_ids[$i] = "'".$registration_ids[$i]."'";
}
}
}
if(!empty($remove_ids)){
$remove_ids_string = implode(', ',$remove_ids);
include_once SCRIPTS.'gcm_server_php/db_functions.php';
$dbf = new DB_Functions();
$res = $dbf->deleteUsers($remove_ids_string);
echo count($remove_ids)." users have unregistered from notifications since the last one was sent out.";
}
}
根据我在这里看到的:
http://developer.android.com/google/gcm/http.html error_codeshttp://developer.android.com/google/gcm/server-ref.html错误代码
我开发了如下代码(尚未测试):
$result = $gcm->send_notification($registration_ids, $message);
$jsonArray = json_decode($result);
if($jsonArray->canonical_ids != 0 || $jsonArray->failure != 0){
if(!empty($jsonArray->results))
{
for($i = 0 ; $i<count($jsonArray->results) ; $i++){
$result = $jsonArray->results[$i];
if(isset($result->message_id) && isset($result->registration_id))
{
// You should replace the original ID with the new value (canonical ID) in your server database
}
else
{
if(isset($result->error))
{
switch ($result->error)
{
case "NotRegistered":
case "InvalidRegistration":
// You should remove the registration ID from your server database
break;
case "Unavailable":
case "InternalServerError":
// You could retry to send it late in another request.
break;
case "MissingRegistration":
// Check that the request contains a registration ID
break;
case "InvalidPackageName":
// Make sure the message was addressed to a registration ID whose package name matches the value passed in the request.
break;
case "MismatchSenderId":
// Invalid SENDER_ID
break;
case "MessageTooBig":
// Check that the total size of the payload data included in a message does not exceed 4096 bytes
break;
case "InvalidDataKey":
// Check that the payload data does not contain a key that is used internally by GCM.
break;
case "InvalidTtl":
// Check that the value used in time_to_live is an integer representing a duration in seconds between 0 and 2,419,200.
break;
case "DeviceMessageRateExceed":
// Reduce the number of messages sent to this device
break;
}
}
}
}
}
