Get a players Steam avatar URL

[Marzouk]

Is it possible for me to find the URL to a players avatar in gmod lua? I would like to use it for some MySQL integrated things but I can't seem to find any way to do this.

You can use the [URL="https://developer.valvesoftware.com/wiki/Steam_Web_API"]Steam Web API[/URL].

You'll need an [URL="http://steamcommunity.com/dev/apikey"]API key[/URL] (absolutely free, no hassle).

Assuming you have the user's [URL="http://wiki.garrysmod.com/page/Player/SteamID64"]64-bit SteamID[/URL] (or have the [URL="http://wiki.garrysmod.com/page/Player/SteamID"]32-bit SteamID[/URL] to [URL="http://wiki.garrysmod.com/page/util/SteamIDTo64"]convert[/URL] from), you can use the [URL="https://developer.valvesoftware.com/wiki/Steam_Web_API#GetPlayerSummaries_.28v0002.29"]GetPlayerSummaries[/URL] interface like so:
http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=XXXXXXXXXXXXXXXXXXXXXXX&steamids=76561197960435530

You need to replace the XXXXX portion with your API key.

Here's a working example where I use HTTP() to send a request to the API and attempt to get the full avatar URL from it:

local key = "XXXXXXXXXXXXXXXXXX" -- replace with your own from the link above

local struct = {
	method     = "get",
	failed     = function( err ) MsgC( Color(255,0,0), "HTTP error: " .. err ) end,
	url        = "http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/",
	parameters = { key = key, streamids = "" }
}

function GetPlayerAvatarURL( sid64, callback )
	struct.success = callback
	struct.parameters.steamids = sid64
	
	HTTP( struct )
end

local function AvatarFromJSON( json )
	local tbl = util.JSONToTable( json )

	-- just in case something went wrong with the request
	if ( !istable( tbl ) or !tbl.response )                 then return false end
	-- most likely an invalid player was given, or they haven't set up their community profile(?)
	if ( !tbl.response.players or !tbl.response.players[1] ) then return false end
	
	return tbl.response.players[1].avatarfull
end



-- Test example using Garry's 64-bit SteamID
local function callback( code, body, headers )
	print( AvatarFromJSON( body ) )
end

GetPlayerAvatarURL( "76561197960279927", callback )

Hope this helps!
