weui怎么在wepy中使用，样式使用的是sass，但是默认的下载是less，请问有没有踩坑方案？尝试了很久都不行，只能自己实现actionsheet了。麻烦各位大佬给条明路

下面附上核心代码       let that = this       wx.getSetting({         success(res) {           if (!res.authSetting['scope.writePhotosAlbum']) {             wx.authorize({               scope: 'scope.writePhotosAlbum',               success(re) {                 that._saveToBlumNet(url)               }             })           } else {             that._saveToBlumNet(url)           }         }       })   _saveToBlumNet (url) {     let that = this     wx.downloadFile({       url: url || that.shareobj.url,       success: function (res) {         wx.saveImageToPhotosAlbum({           filePath: res.tempFilePath,           success(result) {             wx.showToast({               title: '保存成功',               icon: 'success',               duration: 1000             })           },           fail(result) {             wx.showToast({               title: '保存图片：' + result,               icon: 'none',               duration: 1000             })           }         })       },       fail: function (res) {         wx.showToast({           title: '下载图片：' + res,           icon: 'none',           duration: 1000         })       }     })   }

请问下，看了小程序登陆优化调整，要显示的给用户选择登陆的方式，是不是每次超时了都需要用户手登陆？
