HarmonyOS webview浏览器获取定位异常

获取设备位置信息需要先在module.json5文件配置ohos.permission.LOCATION，ohos.permission.APPROXIMATELY_LOCATION权限，如：

{
  "name":
  "ohos.permission.LOCATION",
  "reason":
  "$string:module_desc",
  "usedScene":
  {
    "when":
    "inuse"
  }
}
,
{
  "name":
  "ohos.permission.APPROXIMATELY_LOCATION",
  "reason":
  "$string:module_desc",
  "usedScene":
  {
    "when":
    "inuse"
  }
}
,
{
  "name":
  "ohos.permission.LOCATION_IN_BACKGROUND",
  "reason":
  "$string:module_desc",
  "usedScene":
  {
    "when":
    "inuse"
  }
}

onGeolocationShow中需要设置允许站点地理位置权限请求具体使用,可以参考管理位置权限文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/web-geolocation-permission-V5
