修复可视区域高度问题

  • 通过设置小程序和 iso 安卓APP 不同系统做兼容

app端会默认加入刘海屏高度,计算减去此高度即可

// 获取可视区域高度【兼容】
            getClientHeight(){
                const res = uni.getSystemInfoSync();
                console.log(res.platform,res.statusBarHeight);
                const system = res.platform;
                if ( system === 'iso') {
                    return 44 + res.statusBarHeight;
                }else if( system === 'android' ){
                    return 48 + res.statusBarHeight;
                } else{
                    return 0;
                }
            },

自定义服务器接口

  • 服务器数据接口更改

index.js
保存后重启服务器哈

var router = express.Router();
