React Query的invalidateQueries方法用于使特定查询无效,并重新加载数据。它的作用是告诉React Query重新发起查询请求,以获取最新的数据。 invalidateQueries方法接受一个查询键(query key)作为参数,该键用于标识查询。当调用invalidateQueries方法时,React Query会将该查询标记为无效,并
constinvalidateQueries= () => { queriesToInvalidate.forEach(queryKey=> { InvalidateQueries([queryKey]); }); }; 当你想标记某个查询为过期时,只需从queriesToInvalidate数组中删除相应的查询键。然后调用invalidateQueries函数。 注意:在React Query中,当您调用invalidateQueries时,它会立即触发所有过期的查询。
3.React Query 还会使用queryKey将数据缓存到查询缓存(QueryCache)中 4.可以通过它手动处理查询 queryKey的妙用 1. 使用QueryClient 可以用来与缓存交互,例如清空缓存,发起已声明的请求等。 queryClient.invalidateQueries(['/requestPath']); invalidateQueries:可根据查询键使缓存中的单个或多个查询无效和重新获取。
TanStack Query 官方也提供了一个使用 react-query 获取 React Query GitHub 统计信息的简单示例;可以在StackBlitz 中打开。核心代码如下: import React from 'react' import ReactDOM from 'react-dom/client' import { QueryClient, QueryClientProvider, useQuery, } from '@tanstack/react-query' import { Re...

If the request is successful, we invalidate all queries to get fresh data. In our app it would be just 1 query: user profile to update the name in the header, but just to be sure we invalidate everything. if(resp.data.token){Cookies.set('token',resp.data.token);history.replace(page...
当请求成功后,会触发onSuccess回调,回调中调用queryClient .invalidateQueries,将userData对应的query缓存置为invalidate。 这样,React-Query就会重新请求userData对应query的数据。 三、React-Query 辅助 Hook介绍 1、Hook: (1)useIsFetching 返回应用程序在后台加载或获取的查询的数量(对于应用程序范围内的加载指示器很有...
