FCM 获取 MismatchSenderId [英] FCM getting MismatchSenderId

问题描述

我有一个使用 Google FCM 发送推送通知的应用程序.

I have an application that uses Google FCM for sending push notifications.

当我向一组用户发送推送通知时，我会收到其中一些用户的 MismatchSenderId 响应.尽管如此，所有用户都拥有完全相同的应用程序.一些用户如何获得成功响应而其他用户获得 MismatchSenderId?

When i send a push notification to a group of users, i get a response of MismatchSenderId for some of them. Even though, all users have the exact same application. How can some of the users get a success response and others get a MismatchSenderId?

我进行了很多研究，并确保我添加了 FCM 需要的所有先决条件.

I have researched a lot and made sure I have added all prerequisites that FCM needs.

有什么建议吗?

示例响应:

{"multicast_id":5340432438815499122,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"MismatchSenderId"}]}

编辑 2:

这里是服务器端发送代码(PHP):

Here is the server side sending code (PHP):

$fields = array
(
  'to' => $token,
  'data' => $data
);

$headers = array
(
  'Authorization: key=AIza**************************',
  'Content-Type: application/json'
);

$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, true );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode($fields) );
curl_exec( $ch );
curl_close( $ch );

更新:

该问题似乎已通过 SDK 更新解决.我现在使用的是最新的 com.google.firebase:firebase-messaging:9.6.1，我不再收到MismatchSenderId"了.

It seems that the issue has been resolved with the SDK updates. I am using now the latest com.google.firebase:firebase-messaging:9.6.1, I don't get "MismatchSenderId" anymore.

推荐答案

Firebase 已将其服务器密钥升级到新版本.使用新密钥而不是旧密钥.

Firebase has upgraded their server keys to new version. Use new keys instead of old one.
