在你提供的代码中，有几个地方需要修正和优化。以下是针对代码的逐行检查和修改建议：

1. **获取 QBCore 对象**:
  

QBCore = exports['qb-core']:GetCoreObject()

2. **修复数组索引引用**:
   你在访问 `QBCore.Shared.Items` 的方式不正确，应该使用方括号而非 `item`，正确的写法应该是：
  

local itemData = QBCore.Shared.Items[item]

3. **Notification 函数的定义重复**:
   `Notify` 函数被定义了两次，第二次定义会覆盖第一次，建议只保留一个版本。

4. **Keys 表中的格式问题**:
    `Keys` 表的定义有几个地方语法错误，比如缺少左引号（`"`），应修改为：
  

Keys = {
        ["ESC"] = 322, 
        ["F1"] = 288, 
        -- 继续按此格式修改剩余项
    }

5. **“数值”引用和 “字符串”引用的格式问题**:
   在 `Keys` 和其他地方使用字符串时，都应确保用相同的方式来保持一致性。

6. **地方变量名称的统一性**:
   确保所有局部变量如 `src`, `Player`, `item`, `amount`, 等名称在整个代码中一致。

7. **通知函数的使用**:
   确保只有一个 `Notify` 函数，并且在 `RegisterServerEvent` 和 `RegisterNetEvent` 的事件处理程序中都只调用一次。

8. **整体结构组织**:
   给每个主要部分（如事件处理、功能定义等）添加注释，以提高代码可读性。例如：

-- 添加物品事件
   RegisterServerEvent("d-farmingzone:server:additem")

这是经过修改后的代码片段示例：

QBCore = exports['qb-core']:GetCoreObject()

-- 添加物品事件
RegisterServerEvent("d-farmingzone:server:additem")
AddEventHandler("d-farmingzone:server:additem", function(r)
    local src = source
    local Player = QBCore.Functions.GetPlayer(src)
    local item = r.item
    local amount = r.amount
    local success = false
    local nospace = false

    local itemData = QBCore.Shared.Items[item]
    if itemData then
        if Player.Functions.CanCarryItem(item, amount) then
            success = true
        else
            nospace = true
        end

        if success then
            Notify(src, _U('success', amount, itemData.label), 5000, "success")
            Player.Functions.AddItem(item, amount)
            TriggerClientEvent('inventory:client:ItemBox', src, QBCore.Shared.Items[item], "add")
        elseif nospace then
            Notify(src, _U('nospace'), 5000, "error")
        end
    else
        Notify(src, _U('itemdoenstexist'), 5000, "error")
    end
end)

-- 通知函数
function Notify(source, text, length, type)
    TriggerClientEvent('d-farming:notify', source, text, length, type)
end

-- 其他代码...

请根据这些建议对你的代码进行相应的调整。保持一致的风格和清晰的注释会使代码更加易于维护和理解。如果需要进一步的帮助，请告诉我！
