当我使用此字符串作为令牌发送消息时，它会给我一个错误：

{
"results": [
    {
        "error": {
            "code": "messaging/invalid-registration-token",
            "message": "Invalid registration token provided. Make sure it matches the registration token the client app receives from registering with FCM."
        }
    }
],
"canonicalRegistrationTokenCount": 0,
"failureCount": 1,
"successCount": 0,
"multicastId": 5998201396286625000
}

我认为注册令牌应采用以下格式：
