【运维发布】发布回滚脚本：自动化回滚的脚本设计

-- 发布回滚：脚本编排
local player = class(actor)
local ROLLBACK_STEPS = {
    {desc = "还原配置", cmd = "@RestoreConfig"},
    {desc = "切换代码", cmd = "@SwitchCode"},
    {desc = "重启服务", cmd = "@RestartService"},
}
local function rollback(player, version)
    for i, step in ipairs(ROLLBACK_STEPS) do
        gmexecute(player, step.cmd, version)
        sendmsg(player, 1, 0, "步骤 " .. i .. "/" .. #ROLLBACK_STEPS ..
            "：" .. step.desc .. " 完成。")
    end
    setsysvarex("CurrentVersion", version, true)
    sendcentermsg(player, 255, 0, "回滚到版本 " .. version .. " 完成。", 0, 10)
end
