Question

这是我的代码部分。一切正常，但eslint会出错。

React Hook useEffect缺少依赖项：“ dispatch”和“ getData”。要么包含它们，要么删除依赖项数组react-hooks / exhaustive-deps

我找到了一些解决方案，但都需要在useEffect内移动函数，但我不能。因为有时我在Jsx中调用setData（）函数。

因此，getData不仅在安装组件时运行。

有些类似的问题，但正如我所说；我无法在useEffect中移动函数。答案始终相同：

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

            });
            setLikes(LikesList)
        })
    }

}

useEffect(() => {
    getData()
    return () => {
        setEntries([])
        dispatch(setCurrentPage({type: null, id: null, title: null}))
    }
}, [id, props.location.search])

function getGoodEntriesGeneral() {
    const params = queryString.parse(props.location.search)
    params['guzel'] = true;
    const serialize = obj => Object.keys(obj)
                         .map(key => `${key}=${encodeURIComponent(obj[key])}`).join('&')
    history.push({
        pathname: props.location.pathname,
        search: serialize(params)
    })
}

React创建者提供的eslint设置的新版本强制程序员将所有变量放入数组中。您可以检查https://github.com/facebook/create-react-app/issues/6880#issuecomment-485912528
