This little program will provide a simple API to return all latitude/longitude locations of currently online players on a game realm (designed for use with WoW private servers). No IP/account references are sent from the API to the client, just coordinates.
Additionally supplied is an index.html file to display these locations on a map, given the user supplies his or her own Mapbox API credentials.
To prevent abuse, it will check every minute to update its data, not on each GET request. There are no data stores, but instead caches the data in memory as it is assumed the program will be left running continuously. If used on a very large server with thousands of users needing to be queried frequently, a state service like MongoDB could easily be implemented, but it seems unnecessary. With the ability to query 150 IPs per minute, and with caching, it should keep up relatively well.
- Golang 1.x (built on 1.9)
- An MySQL
accounttable with online accounts (real or fake). TrinityCore/MaNGOS/OregonCore, etc. Literally could be used for anything with online account tables with IP addresses in them, not just WoW servers.
- Rename
config.go.disttoconfig.go - Edit newly renamed
config.gofile to set its MySQL credentials to the game server you're querying online accounts for. - (Optional) To use an example map, edit the
index.htmlfile and change the Mapbox credentials to your own. Changelocalhost:8080to a new URL if you are running the Go program from a different location than localhost.
- Run
go getin the Terminal/Command Prompt inside the program directory. - Run
go build && ./live-player-mapin the Terminal (go build && ./live-player-map.exefor Windows) - Run
index.htmlin the browser with updated credentials to view data.
This program utilizes the free ip-api API to lookup IP address information. Due to its limitation of 150 requests per minute, we have an internal counter to not exceed that threshold, and once hit, waits 1 minute before resuming.
