如何将 channelId 添加到我的通知中？

Question

我编写了一个云函数来向特定设备发送云消息。

export const onGroupInvitationCreate = functions.region('europe-west1').firestore.document('users/{userId}/userGroupInvitations/{invitationId}').onCreate(async (handler, context) => {

    const invitation = GroupInvitationModel.fromFirestoreDocumentData(handler);

    const documentList = await userCollection.doc(invitation.receiverId).collection('userDeviceData')
    .listDocuments();

    const futureDocuments = [];

    for(const documentReference of documentList)
        futureDocuments.push(documentReference.get());

    const deviceDatas = (await Promise.all(futureDocuments)).map(deviceData => DeviceDataModel.fromFirestoreDocumentData(deviceData));

    const futureNotifications = [];

    for(const deviceData of deviceDatas)
    {
        const translator = deviceData.language !== 'nl' ? languages.en : languages.nl;

        const payload: admin.messaging.MessagingPayload = {
            // notification: {
            //     title: `${translator['invitationTitle' as keyof typeof translator]}`,
            //     body: `${invitation.senderDisplayName} ${translator['invitationBody' as keyof typeof translator]} ${invitation.groupDisplayName}`,
            //     clickAction: 'FLUTTER_NOTIFICATION_CLICK',
            // },            
            data: {
                title: `${translator['invitationTitle' as keyof typeof translator]}`,
                body: `${invitation.senderDisplayName} ${translator['invitationBody' as keyof typeof translator]} ${invitation.groupDisplayName}`,
                clickAction: 'FLUTTER_NOTIFICATION_CLICK',
                senderId: invitation.senderId,
                senderDisplayName: invitation.senderDisplayName,
                type: 'invitation',
                sentAt: new Date().toISOString(),
            }
        }

        futureNotifications.push(messaging.sendToDevice(deviceData.cloudMessagingToken, payload));
    }

    await Promise.all(futureNotifications).catch((error) => console.error(`There was an error while notifying receiver ${invitation.receiverId}`, error));

    return Promise.resolve('Status 200');
});

我将如何提供 channelId？我正在使用

messaging.sendToDevice();

它需要一个注册令牌、一个有效负载和选项。我注意到其中 none 个具有属性 channelId。

AndroidConfig 确实有一个属性 channelId，但我在发送通知时找不到如何使用它。

这就是 sendToDevice 接受的参数

sendToDevice(
  registrationToken: string | string[],
  payload: admin.messaging.MessagingPayload,
  options?: admin.messaging.MessagingOptions
): Promise<admin.messaging.MessagingDevicesResponse>;

Answer 1

您需要在 MessagingPayload 的 notification 部分传递 android_channel_id 属性。有关旧版 FCM APIs 接受的所有 Android 相关选项的完整列表，请参阅 https://firebase.google.com/docs/cloud-messaging/http-server-ref#notification-payload-support 中的 table 2b。

如果您想使用 AndroidConfig，您必须先迁移到新的 FCM API（即 send() 方法）。

感谢@Hiranya Jayathilaka 我按照以下方式设置，他的回答是正确的。

 const message: TokenMessage = {
        token: deviceData.cloudMessagingToken,
        data: {
            title: `${translator['messageTitle' as keyof typeof translator]} ${group.displayName}`,
            body: `${sender.displayName} ${translator[type as keyof typeof translator]}`,
            clickAction: 'FLUTTER_NOTIFICATION_CLICK',
            senderId: sender.id,
            senderDisplayName: sender.displayName,
            groupId: group.id,
            type: 'groupMessage',
            messageType: type,
            sentAt: new Date().toISOString(),
        },
        android: {
            priority: 'high',
            notification: {
                channelId: '59054',
            }
        }
    }

    console.log(message);
    console.log('notification sent');

    futureNotifications.push(messaging.send(message));

Answer 3

const message = {
    notification:{
        title: 'title',
        body:'message',
    },
    android: {
        notification: {
            channelId: 'Your notification channelID',
        }
    },
    topic:'topic'
};
