share mixin 重要用于 设置分享类容、重定向Url

import {mapState,mapMutations} from 'vuex'
export default {
    computed:{
        ...mapState('login',['userInfo','redirectUrl']),
    },
    onUnload() {
        if(this.redirectUrl){
            if(this.isLogin){
                const token = uni.getStorageSync('token');
                const getPhone = uni.getStorageSync('getPhone');
                if(token&&!getPhone){
                    this.clearRedirectUrl()
                }
            }
        } 
    },
    methods:{
        ...mapMutations('poster',['GETSHAREINFO']),
        ...mapMutations('login',['GETREDIRECTURL']),
        setShareInfo(shareTitle,title,shareImg,previewImg,statistics){
            let inviteUserId = undefined
            if(this.userInfo){

            }
            var pages = getCurrentPages();
            var page = pages[pages.length - 1];
            let path = '/' + page.route + '?code='+this.code+'&inviteUserId='+ inviteUserId

            this.GETREDIRECTURL({redirectUrl:{url:path,type:1}}) //小程序内部页面
        },

        clearRedirectUrl(){
