react-router - 如何保护核心 ui 中的路由 react

Question

我已经从核心 ui 下载了 react admin 仪表板，现在我需要保护其中定义的仪表板路由，那么我该怎么做，

export default routes;

这是 core ui react admin dashboard的来源

我知道保护在 App.js 中定义的路由，但在这里它们的路由被放置在常量中，任何人都可以告诉我如何保护路由，当且仅当 token 存在时路由应该发生，否则不要。

你可能已经解决了这个问题。但是，如果您仍然卡住，您可以在容器文件夹中的 App.js 或 DefaultLayout 中定义保护路由。

假设您将 token 存储在 localstorage/cookie 中，请在 Switch 块内的 DefaultLayout 中使用以下代码:

{routes.map((route, idx) => {
  return route.component ? (
    <Route
      key={idx}
      path={route.path}
      exact={route.exact}
      name={route.name}
      render={props =>
        get_token_from_storage_or_cookie("tokenName") !== null
       ? (
          <route.component {...props} />
        ) : (
          <Redirect to={{ pathname: "/login" }} />
        )
      }
    />
  ) : null;
})}
<Redirect from="/" to="/dashboard" />
