1.新增隐私设置
2.优化代码 新增uni.authorize判断
_saveCode() {let that = this;console.log('点击了保存图片')console.log(this.result)uni.authorize({scope: 'scope.writePhotosAlbum',success(e) {console.log(e)if (this.result != "") {uni.saveImageToPhotosAlbum({filePath: that.result,success: function() {uni.showToast({title: '二维码保存成功',icon: 'success',duration: 2000});}});}},fail(e){console.log('失败了')console.log(e)uni.openSetting({success(res) {console.log(res.authSetting)}});}})},
