dashboard 页面需要登陆后才能访问,要添加访问权限。
创建一个受保护的路由组件,限制只有登录后才能访问的页面:
// src\components\admin\PrivateRoute.tsx
import { Redirect, Route, RouteProps } from 'react-router-dom'
import { FC } from 'react'
import { isAuth } from '../../helpers/auth'
interface PrivateRouteProps extends RouteProps {
component: React.ComponentType<any>
}
const PrivateRoute: FC<PrivateRouteProps> = ({ component: Component, ...rest }) => {
return (
<Route
{...rest}
render={props => {
const auth = isAuth()
if (auth) {
return <Component {...props} />
}
return <Redirect to="/signin" />
}}
/>
)
}
export default PrivateRoute
