如何强制用户启用位置以使用 C# 在 ASP.NET Core 6 MVC 中访问页面?
How to force user to enable location for accessing a page in ASP.NET Core 6 MVC using C#?
我正在处理一项要求,用户必须启用他的设备位置,以便我可以获得他的位置(纬度、经度)。
- 用户必须启用his/her设备的位置
- 获取用户的确切位置
我该怎么做?
请参考http://www.w3schools.com/html/html5_geolocation.asp
您可以使用 javascript 和 navigator
来实现
function getLocation() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(showPosition,showError);
} else {
x.innerHTML = "Geolocation is not supported by this browser.";
}
}
function showPosition(position) {
x.innerHTML = "Latitude: " + position.coords.latitude + "<br>Longitude: " + position.coords.longitude;
}
function showError(error) {
switch(error.code) {
case error.PERMISSION_DENIED:
x.innerHTML = "User denied the request for Geolocation."
break;
case error.POSITION_UNAVAILABLE:
x.innerHTML = "Location information is unavailable."
break;
case error.TIMEOUT:
x.innerHTML = "The request to get user location timed out."
break;
case error.UNKNOWN_ERROR:
x.innerHTML = "An unknown error occurred."
break;
}
}
