unity C# 如何获取玩家的国家、城市或位置

Question

I've a game where I'm trying to keep my own analytics. No pin point location, is there something similar to SystemInfo class that could give approximate location of the player?

I know I can tap into the GPS but I don't want to make things complicated. Just a simple city or country will do.

Please advise.

Answer 1

You can either ask the user for their details or send a request to your web server where that uses something like ipdata.co to track where the IP address came from.

Answer 2

I had this problem too, so I wanted to make as simple of a solution as possible. Unfortunately, it wasn't easy:

[Serializable]
public class IpApiData
{
    public string country_name;

    public static IpApiData CreateFromJSON(string jsonString)
    {
        return JsonUtility.FromJson<IpApiData>(jsonString);
    }
}


public static IEnumerator SetCountry()
{
    string ip = new System.Net.WebClient().DownloadString("https://api.ipify.org");
    string uri = $"https://ipapi.co/{ip}/json/";


    using (UnityWebRequest webRequest = UnityWebRequest.Get(uri))
    {
        yield return webRequest.SendWebRequest();

        string[] pages = uri.Split('/');
        int page = pages.Length - 1;

        IpApiData ipApiData = IpApiData.CreateFromJSON(webRequest.downloadHandler.text);

        Debug.Log(ipApiData.country_name);
    }
}

This will get the country, no problem. If you want to change it to city, or anything else, you'll just have to add some fields to IpApiData , as per this link: https://ipapi.co/api/#complete-location

You can first take the IP of the player. I think this might helpanswers.unity.com/questions/518346/get-ipv4-adress . Then use any site IP-tracker to find the location. (like ipstack )
