GCM规范ID

Question

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"}]} 

所以它表明，应该由GCM使用最新的REGID但为什么没有显示REGID你应该删除（旧的）？我怎么知道旧regid是什么以及我应该从我的数据库中删除哪一个？

Answer 1

伊兰的答案是正确的，但我发现它仍然有点雾。不过，感谢他，我找到了一个解决方案。

说这是你的回应：

{ 
    "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++; 
} 

从叶兰的回答是：

Since you get a response from Google for each request you send, you should know which Registration IDs were sent to Google in the request that triggered this response. The old Registration ID that you have to delete is the second Registration ID in that request.

这意味着索引和5阵列的 $ registrationIDs []应替换为MY_REG_ID_1和MY_REG_ID_2。

最后检查double值并删除确切的重复项。结果应该是一个包含5个regid的数组（或直接从数组中删除该索引，而不是用MY_REG_ID_＃替换）。

Answer 2

您所包含的GCM响应表明您已向两个注册ID发送消息。这两条消息都成功地在GCM服务中收到。只有第二条消息你有一个规范的注册ID。

由于您收到了Google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哪些注册ID已发送给Google。您必须删除的旧注册ID是该请求中的第二个注册ID。
