【后端接口】recharge：充值触发的发放幂等与订单核对

---充值触发 actor:玩家 order:订单信息
function recharge(actor, order)
    local orderId = order.id
    if getplayvar(actor, "HUMAN", "order_" .. orderId) == 1 then
        release_print("重复充值回调 " .. orderId)
        return
    end
    setplayvar(actor, "HUMAN", "order_" .. orderId, 1, 1)
    -- 首充判断与发放
    if getplayvar(actor, "HUMAN", "first_charge") == 0 then
        setplayvar(actor, "HUMAN", "first_charge", 1, 1)
        giveitem(actor, "首充礼包", 1, 1, "首充奖励")
    end
    addvipexp(actor, order.amount)
end

-- 充值金额与订单的核对：金额以服务端订单为准
function verifyOrder(actor, order)
    local expect = queryOrderAmount(order.id)
    if expect ~= order.amount then
        release_print("金额不符 " .. order.id)
        kick(actor)
        return false
    end
    return true
end
