Cordova Background Fetch ajax 请求未完成且另一个未启动

Question

我目前使用 Cordova Background Fetch 为用户检索任何通知并在本地启动通知。 但是，当应用程序插件启动时，ajax 请求仍然挂起并且第二个没有启动，我认为它是因为 30 秒超时。

我可以就下面的代码或任何其他可以实现该目标的替代方案获得任何帮助。

后台获取插件https://www.npmjs.com/package/cordova-plugin-background-fetch

编码

async function fetchBackgroundNotices(){

var BackgroundFetch = window.BackgroundFetch;

// Your BackgroundFetch event handler.
var onEvent = async function(taskId) {
    
    console.log('[BackgroundFetch] event received', taskId);
    // Required: Signal completion of your task to native code
    // If you fail to do this, the OS can terminate your app
    // or assign battery-blame for consuming too much background-time
    
    var userdata = getUserData(); 
    if(userdata !== null){
        
        //set notice count badge
        $.ajax({
            url: "https://platform.followups.co.ke/api/business/notices/getcount/" + userdata.agenciesid,
            tryCount : 0,
            retryLimit : 3,
            dataType: 'json',
            error: function (){

                this.tryCount++;
                if (this.tryCount <= this.retryLimit) {

                    //try again
                    $.ajax(this).done(embedNoticeCountBadge);
                    return;
                }   

                return;
            },
            method: "GET"
        }).done(embedNoticeCountBadge);
        
        //get the notice messages
        $.ajax({
            url: "https://platform.followups.co.ke/api/business/notices/getunread/" + userdata.agenciesid,
            tryCount : 0,
            retryLimit : 3,
            dataType: 'json',
            data: {
                fetch: BackgroundFetch,
                taskid: taskId
            },
            error: function (){

                this.tryCount++;
                if (this.tryCount <= this.retryLimit) {

                    //try again
                    $.ajax(this).done(function(response){
                        pushNoticeMessages(response);
                        
                        //run the finish background task
                        this.data.fetch.finish(this.data.taskid);
                    });
                    return;
                }   

                return;
            },
            method: "GET"
        }).done(function(response){
            pushNoticeMessages(response);
            
            //run the finish background task
            this.data.fetch.finish(this.data.taskid);
        });
    }
};

// Timeout callback is executed when your Task has exceeded its allowed running-time.
// You must stop what you're doing immediately BackgroundFetch.finish(taskId)
var onTimeout = async function(taskId) {
    
    console.log('[BackgroundFetch] TIMEOUT: ', taskId);
    BackgroundFetch.finish(taskId);
};

var status = await BackgroundFetch.configure({minimumFetchInterval: 15}, onEvent, onTimeout);
console.log('[BackgroundFetch] configure status: ', status);

}

这就是它在控制台上的显示方式
