通用：项目搭建之session设置过期时间

1. session设置过期时间

const webStorage = {
    getItem(storageType, key) {
        if (!['sessionStorage', 'localStorage'].includes(storageType)) {
            return null;
        }

        const storeData = window[storageType].getItem(key);
        if (!storeData) {
            return null;
        }

        const parsedData = JSON.parse(storeData);
        const currentTimestamp = new Date().getTime();

        if (currentTimestamp - parsedData.timestamp <= parsedData.expire) {
            return parsedData.value;
        } else {
            window[storageType].removeItem(key);
        }

        return null;
    },

    /**
     * @param {*} key 保存数据的key
     * @param {*} value 保存的数据
     * @param {*} expire 过期时间，默认为1分钟
     */
    setItem(storageType, key, value, expire = 60000) {
        if (!['sessionStorage', 'localStorage'].includes(storageType)) {
            return;
        }

        const obj = {
            value: value,
            expire: expire,
            timestamp: new Date().getTime()
        }

        const stringfiedData = JSON.stringify(obj);
        window[storageType].setItem(key, stringfiedData);
    }
}
