React Hook useEffect 缺少依赖项（没有在 useEffect 中移动函数）

Question

这是我的部分代码。一切正常，但 eslint 出错。

React Hook useEffect 缺少依赖项：'dispatch' 和 'getData'。要么包含它们，要么移除依赖数组 react-hooks/exhaustive-deps

我找到了一些解决方案，但都说你需要在 useEffect 中移动函数，但我不能。因为我有时会调用 Jsx 中的 setData() 函数。

所以 getData 不仅在组件挂载时运行。

一些类似的问题，但正如我所说；我无法在 useEffect 中移动函数。答案总是一样的：

React Hook useEffect has a missing dependency

React Hook useEffect has a missing dependency: 'list'

export const Complex = (props) => {
// [+] Olmayan başlık tespiti. [+] Var olan başlık tespiti. [-] Daha önce
// açılmış fakat ilk entrysi silinmiş başlıklar.
const params = queryString.parse(props.location.search)

let id = props.location.pathname.split("--")[1];
let str = props.location.pathname.split("--")[0].substr(1);

const data = {
    id: id,
    link: str,
    page: params.sayfa ? parseInt(params.sayfa) : 1,
    isGood: params.guzel ? params.guzel : false
};

}

React 创建者为 eslint 提供的新版本设置强制程序员将所有变量放入数组中。可以查看https://github.com/facebook/create-react-app/issues/6880#issuecomment-485912528
