        data() {
            return {
                banner_list: []
            }
        },
        created() {
            // 请求后台数据
            this.$axios({
                url: this.$settings.base_url + '/home/banners/',
                method: 'get',
            }).then(response => {
                // window.console.log(response.data);
                this.banner_list = response.data;
            }).catch(errors => {
                window.console.log(errors)
            })
