function urlEncode(s)
    s = string.gsub(s, "([^%w%.%- ])", function(c)
        return string.format("%%%02X", string.byte(c))
    end)
    return string.gsub(s, " ", "+")
end
function urlDecode(s)
    s = string.gsub(s, "%%(%x%x)", function(h)
        return string.char(tonumber(h, 16))
    end)
    return s
end

对于urlEncode的优化：

function urlEncode(s)
    s = string.gsub(s, "([^%w%.%-])", function(c)
        if c == " " then
            return "+"
        end
        return string.format("%%%02X", string.byte(c))
    end)
    return s
end
