Firebase 管理 SDK FCM 错误

Question

我在 Dialogflow fulfilments 中使用 6.0.0 版的 firebase admin 来发送 fcm 通知。

admin.messaging().send({
    "message": {
        "notification": {
            "title": "Portugal vs. Denmark",
            "body": "great match!"
        },
        "token": user_info.device_id
    }
})
.then((response) => {
    // Response is a message ID string.
    console.log('Successfully sent message:', response);
})
.catch((error) => {
    console.log('Error sending message:', error);
});

这是我遇到的错误

Answer 1

您的 JSON 将 "message" 作为其顶级密钥：

{
    "message": {
        "notification": {
            "title": "Portugal vs. Denmark",
            "body": "great match!"
        },
        "token": user_info.device_id
    }
}

这是无效的。 "notification" 和 "token" 应该是顶级键：

{
    "notification": {
        "title": "Portugal vs. Denmark",
        "body": "great match!"
    },
    "token": user_info.device_id
}
