需求： 今天发布的消息则返回“今天 12:12”，昨天的话则返回“昨天 20:20”，其他日期则返回3-13或2020-3-13（去年的情况下）

代码：

getPublishTime:()=> (time,full)=>{
            let currentTime = new Date();
            time = new Date(time);
            let currentTimeDay = currentTime.getDate();
            let timeDay = time.getDate();
            let currentTimeYear = currentTime.getFullYear();
            let timeYear = time.getFullYear();
            if(currentTimeYear==timeYear&&currentTimeDay==timeDay){
                return "今天 " + time.getHours() + ":" + (time.getMinutes()<10? '0'+time.getMinutes():time.getMinutes());
            }else if(currentTimeYear==timeYear&&(currentTimeDay-1)==timeDay){
                return "昨天 " + time.getHours() + ":" + (time.getMinutes()<10? '0'+time.getMinutes():time.getMinutes());
            }else if(currentTimeYear==timeYear&&(currentTimeDay-timeDay)>1){
                if(full){
                    return (time.getMonth()+1)+'-'+time.getDate()+' '+time.getHours() + ":" + (time.getMinutes()<10? '0'+time.getMinutes():time.getMinutes());
                }else{
                    return (time.getMonth()+1)+'-'+time.getDate();
                }
            }else if(currentTimeYear>timeYear){
                if(full){
                    return time.getFullYear()+' - '+(time.getMonth()+1)+' - '+time.getDate()+' '+time.getHours() + ":" + (time.getMinutes()<10? '0'+time.getMinutes():time.getMinutes());
                }else{
                    return time.getFullYear()+' - '+(time.getMonth()+1)+' - '+time.getDate();
                }
            }
        }
