HTML5 地理位置功能如何工作?
浏览器如何知道我在哪里?
How can the browser tell where I am?
完全基于注册的IP地址?如果我在代理后面怎么办?
Totally based on registered IP address? What if I'm behind a proxy?
推荐答案
这取决于浏览器及其设置.它可能使用 GPS、基于 WLAN AP 的位置、IP 位置或任何其他可以想到的定位方法.
That would depend on the browser and its settings. It might use GPS, WLAN AP-based location, IP location, or any other conceivable method of locating itself.
浏览器在您的本地计算机上运行，因此即使您使用代理，它也应该能够找到您的实际 IP 地址(除非安全功能阻止将其发送到地理定位服务器以进行查找).是否有任何浏览器足够聪明，可以处理在 NAT 后面(本地机器具有私有 IP)并查找网关的 IP 地址，我不知道.
The browser runs on your local machine, so even if you're behind a proxy, it should be able to find your actual IP address (unless security features prevent it from being sent for lookup to a geolocation server). Whether any browser is smart enough to handle being behind a NAT (with the local machine having a private IP) and looking up the gateway's IP address, that I don't know.
