Firebase 云消息传递 android 优先级属性

Ami*_*min 3 node.js firebase-cloud-messaging firebase-admin

我正在尝试将通知优先级设置为,如此HIGH文档中所述和此处定义的特定参数。但是,当我在云函数中设置此属性时,尝试部署时出现以下错误:

src/index.ts:107:35 - error TS2345: Argument of type '{ tokens: string[]; notification: { title: string; body: any; }; data: { title: any; subtitle: any; body: any; id: any; }; android: { notification: { icon: string; channel_id: string; tag: any; }; priority: string; }; }' is not assignable to parameter of type 'MulticastMessage'.
  The types of 'android.priority' are incompatible between these types.
    Type 'string' is not assignable to type '"normal" | "high" | undefined'.

我明白这意味着我不应该输入字符串。但根据文档,这是预期的类型。不仅如此,我对引号中所指的类型感到非常困惑'"normal | "high" | undefined'。那是什么类型?

这是正在设置的完整消息容器:

const message = {
            tokens: tokens,
            notification: {
                title: snapshot.data().sender_username + " - " + snapshot.data().group_name,
                body: snapshot.data().content
            },
            data: {
                title: snapshot.data().group_name,
                subtitle: snapshot.data().sender_username,
                body: snapshot.data().content,
                id: message_topic
            },
            android: {
                notification: {
                    icon: 'add_circle_outline',
                    channel_id: 'exampleChannelId',
                    tag: message_topic

                },
                priority: "high" // <-- This is where the error is thrown
            }
        };

IDE 由于感知到类型不匹配而不满意。

解决方案是显式键入 android 配置:

import * as admin from 'firebase-admin';

const androidConfig: admin.messaging.AndroidConfig = {
    priority: 'high', 
    ...,
};

const message = {
    ...,
    android: androidConfig,
};

这很好,因为您可以看到可以设置哪些其他配置选项。在这一点上,您还可以明确键入整个消息,在这种情况下,这将是admin.messaging.MulticastMessage
