PrivateRoute 在 reactjs react-router-dom 中不起作用

Question

I am completely stuck when integrating PrivateRoute HOC in my react.js project.

Here is my route file

import React, { Component } from "react";
import { Route, Redirect, Switch, BrowserRouter as Router } from 'react-router-dom';
import Dashboard from "../view/Dashboard/Dashboard";
import Login from "../view/Login/Login";
import Admin from "../view/UserManagement/Admin";
import cookie from 'react-cookies'

const PrivateRoute = ({ component, ...rest }) => {
  const isAuthed = cookie.load('token')
  console.log(isAuthed, 'dddddddddddddddddddd')
  return (
    <Route {...rest} exact
      render = {(props) => (
        isAuthed ? (
          <div>
            {React.createElement(component, props)}
          </div>
        ) :
        (
          <Redirect
            to={{
              pathname: '/login',
              state: { from: props.location }
            }}
          />
        )
      )}
    />
  )
}

class MainPanel extends Component {

  render() {
    return (
      <div style={{ direction: direction }}> 
        <Router>
          <Switch>
            <Route path="/login" component={Login}/>
            <PrivateRoute path="/" component={Dashboard} />
            <PrivateRoute path="/AdminManagement" component={Admin} />
           </Switch>
        </Router>
      </div>
    )
  }
}
export default withNamespaces('common') (MainPanel);

I am totally break my head with this but didn't get rid out of that issue. Why my console inside the PrivateRoute doesn't show the values

Is there any issue with the react and react-router-dom versions

Thank you in advance!!!

Answer 1

The PrivateRoute component that you have is correct, You however only need to re-order your Routes for them to work correctly. /AdminManagement route should come before / since Switch renders the first matching Route and a Route path will also match its prefix path

class MainPanel extends Component {

  render() {
    return (
      <div style={{ direction: direction }}> 
        <Router>
          <Switch>
            <Route path="/login" component={Login}/>
            <PrivateRoute path="/AdminManagement" component={Admin} />
            <PrivateRoute path="/" component={Dashboard} />
           </Switch>
        </Router>
      </div>
    )
  }
}
export default withNamespaces('common') (MainPanel);

Here is how I handle my private routes, maybe it will help you also. I have protectedRoutes as an array with the routes. you can fit them as you like.

 const routes = [ { path: '/login', exact: true, name: 'Login', component: Login, }, ]; const protectedRoutes = [ { path: '/admin', exact: true, name: 'Admin', component: Admin, }, ];

 <Switch> {routes.map((route, idx) => (route.component ? ( <Route key={idx} path={route.path} exact={route.exact} name={route.name} render={props => ( <route.component {...props} /> )} /> ) : (null)))} {protectedRoutes.map((route, idx) => (route.component ? ( <Route key={idx} path={route.path} exact={route.exact} name={route.name} render={props => ( isAuth ? <route.component {...props} /> : <Redirect to="/login" /> )} /> ) : (null)))} </Switch>

LE: added full example based on the original code

 import React, { Component } from 'react'; import { Route, Redirect, Switch, BrowserRouter as Router } from 'react-router-dom'; import Dashboard from '../view/Dashboard/Dashboard'; import Login from '../view/Login/Login'; import Admin from '../view/UserManagement/Admin'; import cookie from 'react-cookies'; const routes = [ { path: '/login', exact: true, name: 'Login', component: Login, }, ]; const protectedRoutes = [ { path: '/', exact: true, name: 'Dashboard', component: Dashboard, }, { path: '/AdminManagement', exact: true, name: 'Admin', component: Admin, }, ]; class MainPanel extends Component { constructor(props) { super(props); this.state = { isAuthed: cookie.load('token'), }, }; render() { const { isAuthed } = this.state; return ( <div style={{ direction: direction }}> <Router> <Switch> {routes.map((route, idx) => (route.component ? ( <Route key={idx} path={route.path} exact={route.exact} name={route.name} render={props => ( <route.component {...props} /> )} /> ) : (null)))} {protectedRoutes.map((route, idx) => (route.component ? ( <Route key={idx} path={route.path} exact={route.exact} name={route.name} render={props => ( isAuth ? <route.component {...props} /> : <Redirect to="/login" /> )} /> ) : (null)))} </Switch> </Router> </div> ) } } export default withNamespaces('common')(MainPanel);

try change library to react-cookie ;

let PrivateRoute = ({ component: Component, cookies, ...rest }) => (
  <Route
    {...rest}
    render={props =>
      cookies.get("name") ? (
        <Component {...props} />
      ) : (
        <Redirect
          to={{
            pathname: "/login",
            state: { from: props.location }
          }}
        />
      )
    }
  />
);
