uni-app的uni.setStorageSync和uni.setStorage缓存数据

setStorageSync
同步存储 

uni.setStorageSync("username","lty")

  同步读取 

let res=uni.getStorageSync("username")
this.username=res

 

setStorage

//异步存储

uni.setStorage({
    key:'id',
    data:80,
    success() {
         console.log('存储成功！')
        }
})

//异步读取

uni.getStorage({
    key:'id',
    success(res){
    console.log(res)
    this.username=res.data
    console.log(this.username)
}

uni-app同步缓存值 设置 读取 删除

//存储一个字符传值
uni.setStorageSync('storage_key', 'hello');

//存储数组前，将数组转为字符串
uni.setStorageSync('mykeymas',JSON.stringify(this.msg))

//同步获取字符串
const value = uni.getStorageSync('storage_key');
console.log('获取的key',value)
    
//将字符串转为对象        
let  con= JSON.parse(uni.getStorageSync('mykeymas'));
console.log('获取的mykeymas',con)

uni.setStorageSync('storage_key', 'hello');  //设置
uni.getStorageSync('storage_key');            //读取
const res = uni.getStorageInfoSync();        //读取所有的值

uni.removeStorageSync('storage_key');        //清除某一个特定的key
uni.clearStorageSync();                      //清除所有的key
