移动端 h5通过scheme打开手机app，其他浏览器都能成功，谷歌浏览器则不能打开，有知道原因吗

    // 打开APP
    function openApp() {
      // android
      var ifr = document.createElement("iframe")

      ifr.setAttribute('src', scheme)

      ifr.setAttribute('style', 'display:none')

      document.body.appendChild(ifr)

      let loadDateTime = Date.now()

      let turn = setTimeout(() => {

        let timeOutDateTime = Date.now()

        if ((timeOutDateTime - loadDateTime) < 1400) {
          guide.style.display = 'none'

          downloadLink.style.display = 'block'

          document.body.removeChild(ifr)

          download()
        } else {
          location.replace('about:blank')

          // window.opener = null
          // window.open('about:blank', '_self', '')
          // window.close()
        }
        clearTimeout(turn)
      }, 1000)
    }
