// 1、window.localStorage   浏览器永久缓存
export const Local = {

	// 获取永久缓存

		return JSON.parse(json);

	// 移除永久缓存
	remove(key: string) {
		window.localStorage.removeItem(key);
	},
	// 移除全部永久缓存
	clear() {
		window.localStorage.clear();
	},
};

// 2、window.sessionStorage 浏览器临时缓存
export const Session = {
	// 设置临时缓存
	set(key: string, val: any) {
		window.sessionStorage.setItem(key, JSON.stringify(val));
	},
