Storage
# 说明
存储模块函数主要是存储相关数据，key-value结构
工具类模块的对象前缀是 storages，例如 storages.create()这样调用

function main(){
let storage= storages.create("123");
logd(storage);
}
main();
```
## storage.putString()

> 适用版本(EC 5.15.0+)
@param key 键
@param value 字符串
@return {bool} true成功 false 失败
```js
function main(){
let storage= storages.create("123");
logd(storage);
//存储数据
let r = storage.putString("key","sdfasfd");
logd(r);

logd(storage.getString("key",""));
}
main();
```
## storage.putInt()

```js
function main(){
let storage= storages.create("123");
logd(storage);
