[Lib] Convert playername to UUID and back (From Mojang Servers)

bigteddy98 unless the player is online, it just returns null.

 

Are you sure you are correctly using this lib? I think you aren't because for this lib it doesn't matter if the player is online or not.

 

Just to keep you up-to-date. Since CraftBukkit now also almost fully supports the UUID system there is no need for using this lib anymore

 

Much faster way:

Code:java

    public static String getUniqueIdFromMojang(String name) {
        try {
            URL url = new URL("[url]https://api.mojang.com/users/profiles/minecraft/[/url]" + name);
            BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
 
            Object obj = jsonParser.parse(in);
            JSONObject jsonObject = (JSONObject) obj;
 
            String uuid = (String) jsonObject.get("id");
 
            uuid = uuid.replaceAll("(\\w{8})(\\w{4})(\\w{4})(\\w{4})(\\w{12})", "$1-$2-$3-$4-$5");
 
 
            return uuid;
        } catch (Exception e) {
            return "Player not found or Mojang server down!";
        }
    }

 

Why not just create a hashmap and collect players uuid's on join? Then do something like this

public static UUID getUUID(String playerName){
UUID uuid = null;
HashMap<UUID, String> players = MyPlugin.players;
Set<Map.Entry<UUID, String>> keys = players.entrySet();
for(Entry<UUID, String> key : keys){
if(key.getValue().equalsIgnoreCase(playerName)){
uuid = key.getKey();
}
}
return uuid;
}

Not sure how well this would perform on a large server though
