方案 1 自定义 url 协议

• 该方案适合页面传参给 app
• 缺点不是 100%稳定，有极小概率不成功

function clickFun() {
    location.href = `scancode://details?id=${state.params.uid}`
}

scancode  //与App协商的协议
details   //当前页面地址

2. app端拦截该协议做对应处理

方法传递(常用)

window.appMethod = {
  viewAll(params = '') {
    let u = navigator.userAgent
    let isiOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/)
    let isAndroid = u.indexOf('Android') > -1 || u.indexOf('Adr') > -1 //android终端
    if (isiOS) {
      // window.webkit.messageHandlers.jsShowDialog.postMessage('lalalalalalal');
      window.webkit.messageHandlers.goBackHome.postMessage({ params })
    } else if (isAndroid) {
      window.android.goBackHome({ params })
    }
  }
}

function clikFun() {
  appMethod.viewAll()
}

App 或者 h5 多层次页面返回指定页面注意事项

router.go(-2) // 相当于 history.go(-2):后退+刷新， -2代表要返回的页面层次， 如：-1为上一个页面

在 iOS 桌面生成网页快捷方式图标(Web Clip)
