Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function. 无法对未安装的组件执行React状态更新。这是一个非操作,但它表明应用程序中...
Can’t perform a React state update on an unmountedcomponent. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function. 这是因为我们在使用异步调用时,造成了内存泄漏。 为什么异步调用可能会内存泄漏?
如果使用的是 react18 以下的版本,在开发中可能会经常出现这种警告,出现这种警告是因为:组件已经被卸载了,但依然去 setState,可能会导致内存泄漏。通常这种情况出现在异步请求的情况下,组件已经卸载,请求才完成,并且又去设置了状态就会出现该警告。为了解决该问题,封装了一个 useState,代码如下: import{Dispatch,SetSta...

在React开发中,这样的报错会经常遇到:Warning: Can't perform a React state update on an unmounted component. 原因就是报错中所说:无法对已卸载的组件执行react状态更新。 假设现在我们正在A页面调接口请求数据,请求成功后setState()更新数据,这是没有问题的。
