javascript - Navigator.geoLocation.getCurrentPosition 不工作的问题

Question

我正在制作一个名为“Chicken Logger”的小型移动网络应用程序，用户可以在其中选择特定类型的鸡并在下一页中输入相关数据。

我的问题是我需要使用 Navigator.geolocation 来获取纬度和经度。

该代码在我的桌面 chrome 浏览器上运行良好，但在我的手机上，由于某种原因，它一直抛出错误 Location permission denied。

我已经尝试清除并重置手机上的网站设置，但仍然无法正常工作。我确保也授予 Chrome 位置访问权限。

附言我的网络应用程序托管在我电脑的本地主机上，我已将手机连接到电脑的热点以访问本地主机。另外，我使用的是华为 Mate 20 Pro。

基本上用户一打开“入口页面”，就会被要求位置权限。但我没有得到要求。直接报错。

下面是我的JS代码:

$(document).delegate("#entry_page","pageinit",function()
{

  if (navigator.geolocation) {
       navigator.geolocation.getCurrentPosition(onSuccess, onError);
    }
});


function onSuccess(position)
{
  latitude = position.coords.latitude;
  longitude = position.coords.longitude;
  alert(latitude);
  today = new Date();
  date = today.getDate()+'/'+(today.getMonth()+1)+'/'+today.getFullYear();
  time = today.getHours() + ":" + today.getMinutes() + ":" + today.getSeconds();
  dateTime = date+' '+time;
  alert(dateTime);



}

function onError(error) {
  var txt;
  switch(error.code)
  {
    case error.PERMISSION_DENIED:
    txt = 'Location permission denied';
    break;
    case error.POSITION_UNAVAILABLE:
    txt = 'Location position unavailable';
    break;
    case error.TIMEOUT:
    txt = 'Location position lookup timed out';
    break;
    default:
    txt = 'Unknown position.'
  }
  alert(txt)
}

你的问题是 Geolocation API仅适用于 HTTPS(安全上下文)，不适用于 HTTP，因此拒绝许可。
来自docs ,

This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

另请参阅您的 Browser Compatibilty .

要使用Nginx 启用HTTPS，您必须生成SSL 证书并修改配置文件。关注this manual了解详细步骤。
