我想使用身份验证进行安全路由。我已经在App.jsx文件中定义了路由。我正在使用“路线”来定义要渲染的组件。
在App.jsx中
<Route
path='/dashboard'
exact={true}
render={(props) => <Dashboard {...props} user={user}
handleChildFunc={this.handleChildFunc}/>}
/>
上面的代码可以正常工作。我想像下面这样确保安全。
<PrivateRoute
path='/dashboard'
exact={true}
render={(props) => <Dashboard {...props} user={user}
handleChildFunc={this.handleChildFunc}/>}
/>
在PrivateRoute.jsx
const PrivateRoute = ( props ) => {
const user = "token from cookie"; // i will fetch token stored in cookie
if(user !== null) {
return <Route />;
}
else {
return <Redirect to="login" />
}
}
如果存在令牌,则渲染组件。否则,请重定向到/ login。

您可以像PrivateRoute
一样
<PrivateRoute
path='/dashboard'
exact={true}
component={Dashboard}
handleChildFunc={this.handleChildFunc}
/>
const PrivateRoute = ({ component: Component, handleChildFunc, ...rest }) => {
const user = "token from cookie";
return <Route {...rest} render={(props) => (
user !== null
? <Component {...props} user={user} handleChildFunc={handleChildFunc}/>
: <Redirect to='/login' />
)}
/>
}

可接受的答案很好,但是当我们需要我们的组件来反映URL的更改时并不能解决问题。
说,您的组件具有以下代码:
abs(d)
您更改了网址:
export const Customer = (props) => {
const history = useHistory();
...
}
const handleGoToPrev = () => {
history.push(`/app/customer/${prevId}`);
}
import React from 'react';
import { Redirect, Route } from 'react-router-dom';
import store from '../store/store';
export const PrivateRoute = ({ component: Component, ...rest }) => {
let isLoggedIn = !!store.getState().data.user;
return (
<Route {...rest} render={props => isLoggedIn
? (
<Component key={props.match.params.id || 'empty'} {...props} />
) : (
<Redirect to={{ pathname: '/login', state: { from: props.location } }} />
)
} />
)
}

简单!
export default function RouteComponent() {
const user = useContext(UserContext);
return (
<Router>
{user.islogin ? (
<div className="main_container">
<Nav />
<Switch>
<Route exact path="/">
<Home />
</Route>
<Route path="/NewActiv">
<NewActiv />
</Route>
</Switch>
</div>
) : (
<Switch>
<Route exact path="/">
<Login />
</Route>
</Switch>
)}
</Router>
);
}
export default function RouteComponent() {
const user = useContext(UserContext);
return (
<Router>
{user.islogin ? (
<div className="main_container">
<Nav />
<Switch>
<Route exact path="/">
<Home />
</Route>
<Route path="/NewActiv">
<NewActiv />
</Route>
</Switch>
</div>
) : (
<Switch>
<Route exact path="/">
<Login />
</Route>
</Switch>
)}
</Router>
);
}
