GCM規範ID

Question

有1臺設備的多個regids當GCM返回規範ID錯誤：

{"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，應該由GCM使用最新的REGID但爲什麼沒有顯示REGID你應該刪除（舊的）？我怎麼知道舊regid是什麼以及我應該從我的數據庫中刪除哪一個？

Answer 1

伊蘭的答案是正確的，但我發現它仍然有點霧。不過，感謝他，我找到了一個解決方案。

說這是你的迴應：

{ 
    "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個消息2是重複的。

這是我將消息發送到服務器的方式：

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

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

從葉蘭的回答是：

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.

這意味着索引和5陣列的 $ registrationIDs []應替換爲MY_REG_ID_1和MY_REG_ID_2。

最後檢查double值並刪除確切的重複項。結果應該是一個包含5個regid的數組（或直接從數組中刪除該索引，而不是用MY_REG_ID_＃替換）。

Answer 2

您所包含的GCM響應表明您已向兩個註冊ID發送消息。這兩條消息都成功地在GCM服務中收到。只有第二條消息你有一個規範的註冊ID。

由於您收到了Google發送的每個請求的回覆，因此您應該知道在觸發此回覆的請求中哪些註冊ID已發送給Google。您必須刪除的舊註冊ID是該請求中的第二個註冊ID。
