【运维发布】服务降级预案：核心链路的保底方案

-- 服务降级：降级定义
local player = class(actor)
local DEGRADABLE = {rank = true, achievement = true, socialDot = true}
local degradSwitch = {}
local function isDegraded(funcName)
    return degradSwitch[funcName] == true
end
local function degradedResponse(player, funcName)
    sendmsg(player, 1, 0, funcName .. " 功能暂时维护中。")
end

-- 降级执行：关闭与恢复
local player = class(actor)
local function toggleDegradation(player, funcName, state)
    if DEGRADABLE[funcName] == nil then
        sendmsg(player, 1, 0, "未知功能，不可降级。")
        return
    end
    degradSwitch[funcName] = state
    setsysvarex("Degrad_" .. funcName, state and 1 or 0, true)
    sendmsg(player, 1, 0, funcName .. " 已" .. (state and "关闭" or "恢复") .. "。")
end
