1，导入的validatenull函数是用来判断是否为空

/**
 * 判断是否为空
 */
export function validatenull(val) {
    if (typeof val == 'boolean') {
        return false;
    }
    if (typeof val == 'number') {
        return false;
    }
    if (val instanceof Array) {
        if (val.length == 0) return true;
    } else if (val instanceof Object) {
        if (JSON.stringify(val) === '{}') return true;
    } else {
        if (val == 'null' || val == null || val == 'undefined' || val == undefined || val == '') return true;
        return false;
    }
    return false;
}

2，导入的website中配置的key

website.js中的配置的key: 'peacock',//配置主键,目前用于存储
