当1个设备有多个注册时,GCM会返回规范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"}]}
所以它显示了GCM应该使用的最新regid,但为什么不显示你应该删除的regid(旧的)?我怎么知道旧的regid是什么以及我应该从我的数据库中删除哪一个?

说这是你的回答:
{
"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"
}
]
}
正如您所看到的,7条消息中有2条是重复的。
这是我向服务器发送消息的方式:
$tokenResult = mysql_query("SELECT reg_ids FROM table_with_regids"); //
$i = 0;
while($row = mysql_fetch_array($tokenResult)) {
$registrationIDs[$i] = $row['reg_ids'];
$i++;
}
来自Eran回答的:
由于您收到Google针对您发送的每个请求的回复,因此您 应该知道在请求中向Google发送了哪些注册ID 这引发了这种反应。您必须使用的旧注册ID delete是该请求中的第二个注册ID。
这意味着数组 $ registrationIDs [] 的索引 2 和 5 应替换为 MY_REG_ID_1 和 MY_REG_ID_2 。
最后检查double值并删除完全相同的重复项。结果应该是一个包含5个regids的数组(或直接从数组中删除该索引,而不是替换为MY_REG_ID _#)。

您包含的GCM响应表示您向两个注册ID发送了一条消息。这两条消息都是在GCM服务中成功收到的。仅针对第二条消息,您获得了规范的注册ID。
由于您收到Google针对您发送的每个请求的回复,因此您应该知道在触发此回复的请求中向Google发送了哪些注册ID。您必须删除的旧注册ID是该请求中的第二个注册ID。
