GCM规范IDGCM规范ID(GCM canonical id)

具有1台设备的多个regids当GCM返回规范ID错误：

{"multicast_id":xxxx,"success":2,"failure":0,"canonical_ids":1,"results":[{"message_id":"xxxxx"},{"registration_id":"newest reg ID here","message_id":"xxxxxx"}]}

因此，它表明，应该由GCM可以使用，但为什么没有显示你应该删除REGID（旧）最新的REGID？ 我怎么知道老REGID是什么，哪一个我应该从我的数据库中删除？

Answer 1:

伊兰的答案是正确的，但我发现它还是有点云里雾里我。 然而，由于他，我找到了解决办法。

之所以这样说，是你的回应：

{
   "multicast_id":xxxxx,
   "success":7,
   "failure":0,
   "canonical_ids":2,
   "results":[
      {
         "message_id":"0:xxx%xxxxx"
      },
      {
         "message_id":"0:xxx%xxxxx"
      },
      {
         "registration_id":"MY_REG_ID_1",
         "message_id":"0:xxx%xxxxx"
      },
      {
         "message_id":"0:xxx%xxxxx"
      },
      {
         "message_id":"0:xxx%xxxxx"
      },
      {
         "registration_id":"MY_REG_ID_2",
         "message_id":"0:xxx%xxxxx"
      },
      {
         "message_id":"0:xxx%xxxxx"
      }
   ]
}

正如你可以看到7个消息2是重复的。

这是我将消息发送到服务器的方式：

$tokenResult = mysql_query("SELECT reg_ids FROM table_with_regids"); //
$i = 0;
while($row = mysql_fetch_array($tokenResult)) {

     $registrationIDs[$i] = $row['reg_ids'];
     $i++;
}

从伊兰的回答：

既然你从谷歌为每一个响应请求你送，你应该知道它的注册ID是在触发此响应的请求发送给谷歌。 你必须删除旧的注册ID是该请求的第二个注册ID。

这意味着，在阵列$ registrationIDs []的索引2和5应与MY_REG_ID_1和MY_REG_ID_2代替。

最后检查双重价值并删除确切的重复。 结果应该是用5个regids（或直接删除从您的阵列，而不是与MY_REG_ID_＃替换该索引）的阵列。

Answer 2:

你包括GCM响应表明你传话给两个注册的ID。 这两个消息在GCM服务收到成功。 只有第二个消息你有一个规范的注册ID。

既然你从谷歌为每一个响应请求你送，你应该知道它的注册ID是在触发此响应的请求发送给谷歌。 你必须删除旧的注册ID是该请求的第二个注册ID。
