function FileRead()
	local file = io.open("gui-config.json","r");
	local json = file:read("*a");
	file:close();
	return json;
end

function FileWrite()
	local file = io.open("gui-config.json","w");
	file:close();
end

local cjson = require("cjson");
local file = FileRead();
local json = cjson.decode(file);
for i,w in ipairs(json.configs) do
	print("server: " .. w.password)
	print("server_port: " .. w.server_port)
	print("password: " .. w.password)
	print("method: " .. w.method .. 'n')
end
