php - 针对多个 registration_ids 时哪个 fcm 注册 id 失败

Question

我在 php 中从服务器端向几个注册 ID 发送通知。这是请求:

public function androidPushNotification($registration_ids, $title, $message) {
    $msg = array (
            'message' => $message,
            'title' => $title 
    );

    $fields = array (
            'registration_ids' => $registration_ids,
            'data' => $msg 
    );
    
    $headers = array (
            'Authorization: key=' . $this->API_ACCESS_KEY,
            'Content-Type: application/json' 
    );
    
    $ch = curl_init ();
    curl_setopt ( $ch, CURLOPT_URL, $this->GCM_URL );
    curl_setopt ( $ch, CURLOPT_POST, true );
    curl_setopt ( $ch, CURLOPT_HTTPHEADER, $headers );
    curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, true );
    curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, false );
    curl_setopt ( $ch, CURLOPT_POSTFIELDS, json_encode ( $fields ) );
    $result = curl_exec ( $ch );
    curl_close ( $ch );
    
    return $result;
}

registration_ids 变量在一个数组中有两个注册 ID，其中一个来自客户端应用程序的旧安装，另一个是当前的。

我收到了来自 fcm 的回复:

{
  "multicast_id": 7860323906688398625,
  "success": 1,
  "failure": 1,
  "canonical_ids": 0,
  "results": [
    {
      "error": "NotRegistered"
    },
    {
      "message_id": "0:1478735313889582%1b153de0f9fd7ecd"
    }
  ]
}

我怎么知道哪个注册id失败了？

是否有其他方法可以获取此信息？

我找到了答案:

结果数组与注册 ID 的顺序相同。例如，如果请求是:

$fields = array (
            'registration_ids' => array('123456','987654'),
            'data' => array ('message' => 'This is the message','title' => 'Hi there!')
);

示例响应:

{
  "multicast_id": 7860323906688398625,
  "success": 1,
  "failure": 1,
  "canonical_ids": 0,
  "results": [
    {
      "error": "NotRegistered"
    },
    {
      "message_id": "0:1478735313889582%1b153de0f9fd7ecd"
    }
  ]
}

注册失败的id是123456。

来自 gcm 文档:

Here are JSON results for 6 recipients (IDs 4, 8, 15, 16, 23, and 42 respectively) with 3 messages successfully processed, 1 canonical registration token returned, and 3 errors:

{ 
  "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"}
  ]
}

In this example:

• First message: success, not required.
• Second message: should be resent (to registration token 8).
• Third message: had an unrecoverable error (maybe the value got corrupted in the database).
• Fourth message: success, nothing required.
• Fifth message: success, but the registration token should be updated in the server database (from 23 to 32).
• Sixth message: registration token (42) should be removed from the server database because the application was uninstalled from the
  device.

希望对你有帮助，谢谢。
