uni app检测缓存并清理缓存

app端需要做清理缓存功能

1,组件里面的事件

清除缓存{{storageSize}}

 2，script里面的js部分，清除完后跳到登录页面

data() {return {storageSize:'0M',}},
onLoad() {this.getStorageSize()//获取缓存},methods: {//获取app的缓存getStorageSize:function(){let that = this;uni.getStorageInfo({success(res) {//console.log(res.keys);//console.log(res.limitSize);let size = res.currentSize;if (size < 1024) {that.storageSize = size + ' B';} else if (size/1024>=1 && size/1024/1024<1) {that.storageSize = Math.floor(size/1024*100)/100 + ' KB';} else if (size/1024/1024>=1) {that.storageSize = Math.floor(size/1024/1024*100)/100 + ' M';}}})},//删除 缓存clearStorage:function (){let that = this;uni.showModal({title:'提示',content:'确定清除缓存吗?',confirmText:'立即清除',success(res) {if(res.confirm){uni.clearStorageSync();//重新获取并显示清除后的缓存大小that.getStorageSize();uni.showToast({title:'清除成功',icon:'none'})//清除完后跳到登录页面setTimeout(()=>{uni.redirectTo({url:'/pages/login/login',animationType: 'pop-in',animationDuration: 200})},1300)}}})},}
