-  * 缓存数据优化
 
-  * var cache = require('utils/cache.js');
 
-  * import cache from '../cache'
 
-  * 使用方法 【
 
-  *     一、设置缓存
 
-  *         string    cache.put('k', 'string你好啊');
 
-  *         json      cache.put('k', { "b": "3" }, 2);
 
-  *         array     cache.put('k', [1, 2, 3]);
 
-  *         boolean   cache.put('k', true);
 
-  *     二、读取缓存
 
-  *         默认值    cache.get('k')
 
-  *         string    cache.get('k', '你好')
 
-  *         json      cache.get('k', { "a": "1" })
 
-  *     三、移除/清理  
 
-  *         移除: cache.remove('k');
 
-  *         清理:cache.clear(); 
 
-  * 】
