Whitelist System (WEB API)

DaveHUN · February 11, 2023

I want a script that queries the serial from a specific web, if the serial is there, it can connect to the server, essentially a whitelist system

FLUSHBICEPS · February 11, 2023

local serial = getPlayerSerial (getLocalPlayer())
local allowedSerials = { -- List of allowed serials
    "12345678901234567890123456789012",
    "23456789012345678901234567890123",
    "34567890123456789012345678901234"
}

function isSerialAllowed(serial)
    for i, allowedSerial in ipairs(allowedSerials) do
        if serial == allowedSerial then
            return true
        end
    end
    return false
end

addEventHandler("onClientResourceStart", resourceRoot,
    function()
        if not isSerialAllowed(serial) then
            -- Kick the player if their serial is not allowed
            kickPlayer("Your serial is not on the whitelist.")
        else
            -- Connect to the server if the serial is allowed
            -- Replace "server.example.com" with the address of your server
            triggerServerEvent("connectToServer", resourceRoot, "server.example.com")
        end
    end
)

addEvent("connectToServer", true)
addEventHandler("connectToServer", root,
    function(serverAddress)
        -- Connect the player to the specified server
        -- Replace "serverPassword" with the password for your server
        connect(serverAddress, "serverPassword")
    end

not what I meant
I would like you to download the serials from a website
eg testpage.com/serials.txt
and if it is included, it will connect

Rilot · February 12, 2023

Just create a database table for it, and query it, and check if the player's serial is there when they connect, if not, use cancelEvent on onPlayerConnect

hi welcome to forum, i have prepared and tested a code for you, it works,and add it to the whitelist.json one below the other like this,If you have more problems, you can open a new thread.

>> Lua <<

local WHITELIST_API = "http://localhost/whitelist.json" --change with your url

addEventHandler("onPlayerJoin", root,
   function()
      local player_ = source
      callRemote(WHITELIST_API, 
      function(response)
         if(not isElement(player_)) then return end
         if(response == "ERROR") then return end 
         local playerSerial = getPlayerSerial(player_)

         for _,serial in ipairs(response) do
            if(playerSerial == serial) then return end
         end

         kickPlayer(player_, "You are not authorized to access this server")
      end, player_)
   end
)

addEventHandler("onResourceStart", resourceRoot,
   function()
      local players = getElementsByType("player")
      callRemote(WHITELIST_API, 
      function(response)
         if(response == "ERROR") then return end

         for _,player in ipairs(players) do
            if(isElement(player)) then 
              local playerSerial = getPlayerSerial(player)

              kickPlayer(player, "You are not authorized to access this server")
            end
         end

      end, players)
   end

and it could be resolved that only the series would be included in the file

Is your problem fixed?

Addlibs · February 13, 2023

I'd point out @Shady1's solution does not scale well as the whitelist gets bigger.

It would be more ideal to, on start-up, and then periodically (or on command like refreshwhitelist) download the list, store it in a Lua table in a [serial] = bool structure and look-up that table onPlayerConnect, and cancelEvent(true) if serial not present (which also benefits the server process as a good part of player join sequence is aborted earlier, including the construction of a player element). This way you don't download the whole list every time a player joins, parse it every time a player joins, and iterate thought it every time a player joins. Lua table look-ups benefit from hashing, leading to much faster lookup speeds than iterating thought the list, provided the list is large enough (could be as little as 5 entries for benefits to show up but I haven't tested it) (otherwise hashing could be more expensive).

Upvoting. This way you can indeed do cancelEvent (true, "You are not whitelisted") onPlayerConnect and this will effectively prevent the player from connecting with that custom message. This is prettier than kickPlayer which you are doing with a certain delay by getting the result of callRemote.

you're right, I thought about that, but I chose this way to keep the list updated.
Lua

local WHITELIST_API = "http://localhost/whitelist.json" --change with your url
local serialWhitelist = {}

function updateWhitelist()
   for serial,_ in pairs(serialWhitelist) do
      serialWhitelist[serial] = nil
   end
   callRemote(WHITELIST_API, 
      function(response)
      if(response == "ERROR") then outputDebugString("Unable to get to Whitelist File.", 1) return end
      for _,serial in ipairs(response) do
         serialWhitelist[serial] = true
      end
      outputDebugString("Whitelist Updated Succesfuly!")
      
      for _,player in ipairs(getElementsByType("player")) do
         if(isElement(player)) then
            local playerSerial = getPlayerSerial(player)
            if(not serialWhitelist[playerSerial]) then
               kickPlayer(player, "You are not authorized to access this server")
            end
         end
      end
     
   end)
end

addEventHandler("onResourceStart", resourceRoot,
   function()
      callRemote(WHITELIST_API, 
      function(response)
         if(response == "ERROR") then return outputDebugString("Unable to get to Whitelist File.", 1) end
         for _,serial in ipairs(response) do
            serialWhitelist[serial] = true
         end

         for _,player in ipairs(getElementsByType("player")) do
            if(isElement(player)) then
               local playerSerial = getPlayerSerial(player)
               if(not serialWhitelist[playerSerial]) then
                  kickPlayer(player, "You are not authorized to access this server")
               end
            end
         end

      end)
   end
)

addEventHandler("onPlayerConnect", root,
   function(_, _, _, playerSerial)
      if(not serialWhitelist[playerSerial]) then
