FCM 在使用 PHP 发送推送通知之前验证设备令牌

2022-01-18 00:00:00 firebase php firebase-cloud-messaging

我的数据库中有 fcm 令牌，并且某些令牌用于发送推送通知.

I have fcm tokens in my database and for some tokens are used to send push notifications.

一切都按要求正常工作.但是由于我得到了一些设备令牌，因此需要进行优化

Everything is working fine as required. But there is optimization required since some device token I am getting 

string(116)
"{
"multicast_id": 1234,
"success": 0,
"failure": 1,
"canonical_ids": 0,
"results": [{
  "error": "NotRegistered"
}]
}
"

如果在发送推送通知之前已经注册，可以帮助我验证设备令牌吗?

Could any help me verify device token if registered already before sending push notification?

推荐答案

您可以使用 实例 ID 服务器参考 GET API.如果您收到类似下面的响应，则表示该令牌仍然有效.

You can verify if a token in your database is still valid or not using the Instance ID Server Reference GET API. If you got a response similar to below, it means that the token is still valid.

GET 请求示例:

https://iid.googleapis.com/iid/info/nKctODamlM4:CKrh_PC8kIb7O...clJONHoA?details=true
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA

示例结果

HTTP 200 OK
{
  "application":"com.iid.example",
  "authorizedEntity":"123456782354",
  "platform":"Android",
  "attestStatus":"ROOTED",
  "appSigner":"1a2bc3d4e5",
  "connectionType":"WIFI",
  "connectDate":"2015-05-12
  "rel":{
    "topics":{
      "topicname1":{"addDate":"2015-07-30"},
      "topicname2":{"addDate":"2015-07-30"},
      "topicname3":{"addDate":"2015-07-30"},
      "topicname4":{"addDate":"2015-07-30"}
    }
  }
}
