Firebase 不发送推送通知

Question

我曾经发送推送通知，其中只有短信。 当时的payload结构不同，利用了function“sendToDevices(token,payload)”。 但是现在我想向其中包含图像的多个设备发送推送通知，因此我正在使用“sendMulticast(payload)”function。它可以工作到 Firebase，这意味着我可以看到控制台消息“推送通知发送”在 Firebase 控制台中，但未发送任何通知。 此外，我在控制台中测试了有效负载，一切似乎都正常。

旧代码及其有效载荷

exports.sendPushNotificationToAllDevices = functions.https.onRequest((request, response) => {
    const domain = request.body.Domain;
    if (typeof domain == "undefined" || domain == null || domain == "") {
        response.status(400).send("Domain is empty.");
        return;
    }
    const url = domain + '/Users';
    admin.database().ref(url).once('value')
        .then(snapshot => {
            let tokens = [];
            let counter = 0;
            const count = snapshot.numChildren();
            
            snapshot.forEach(function (data) {
                counter++;
                const token = data.val().FirebaseToken;
                if (typeof token !== "undefined" && token !== null && token != "") {
                    tokens.push(token);
                }
            });
            let uniqeTokens = [...new Set(tokens)];
            if (uniqeTokens.length > 0) {
                const payload = getNotificationPayload(request);
                console.log(uniqeTokens.length);
                const tokensChunk = chunk(uniqeTokens,999);
            
                tokensChunk.forEach(function(tokens){
                    sendPushNotificationTo(tokens, payload); // sendToDevice() function is used.
                });
            }
        });
    response.status(200).send("sending");
});

旧的有效载荷结构

return {
        notification: {
            title: notificationTitle,
            body: notificationBody,
            clickAction: clickAction,
            sound: 'default'
        },
        data: notificationData
    };

新代码结构

exports.sendPushNotificationToAllDevices = functions.https.onRequest((request, response) => {
    const domain = request.body.Domain;
    if (typeof domain == "undefined" || domain == null || domain == "") {
        response.status(400).send("Domain is empty");
        return;
    }
    const url = domain + '/Users';
    admin.database().ref(url).once('value')
        .then(snapshot => {
            let tokens = [];
            let counter = [];
            const count = snapshot.numChildren();
            snapshot.forEach(function (data){
                counter++;
                const token = data.val().FirebaseToken;
                if (typeof token !== "undefined" && token !== null && token != "") {
                    tokens.push(token);
                }
            });
            let uniqueTokens = [...new Set(tokens)];
            if (uniqueTokens.length > 0) {
                var payload = getNotificationPayload(request);
                const tokensChunk = chunk(uniqueTokens, 999);
                tokensChunk.forEach(function(tokens){
                    payload['tokens'] = tokens;
                    sendPushNotificationTo(payload); // sendMulticast() function is used.
                });

新的 function“sendMulticast()”的有效负载结构不正确。

所需的有效负载结构

let message = {
        notification: {
            title: notificationTitle,
            body: notificationBody,
            // clickAction: clickAction,
            // sound: 'default',
        },
        data: notificationData,
        android: {
            notification: {
                sound: 'default'
            }
        },
        apns: {
            payload: {
                aps: {
                    "mutable-content": 1,
                    sound:'default',
                }
            }
        }
    };

    if (typeof clickAction === 'string' || clickAction !== "") {
        message["android"]["notification"]["click_action"] = clickAction;
    }
    if (typeof imageURL !== "undefined" && imageURL !== null && imageUrl !== "") {
        message["android"]["notification"]["imageUrl"] = imageUrl;
    }
    return message;

sendMulticast() 不支持 ClickAction 和 Sound，send() 蚀刻类型为 function
