réagir à l'avertissement computedMatch concernant certains problèmes de cas?

J'ai des accessoires nommés isAuthenticated et cela montre également que certains avertissements de cas persistent dans ma console. S'il te plaît vérifie le.

import React,{Component} from "react";
import {BrowserRouter as Router, Switch, Route} from "react-router-dom";
import LogoutHome from './Logout_Home';
import SignIn from '../Components/SignIn';
import jwt_decode from 'jwt-decode';
import {setCurrentUser} from '../actions/authActions';
import SignUp from '../Components/SignUp';
import setAuthToken from '../util/setAuthToken';
import AboutUs from '../containers/AboutUs';
import store from '../store';
import {connect} from "react-redux";
// check for TOKEN
if (localStorage.jwtToken) {
  // Set auth token header auth
  setAuthToken(localStorage.jwtToken);
  // Decode token and get user info and exp
  const decoded = jwt_decode(localStorage.jwtToken);
  // Set user and isAuthenticated
  store.dispatch(setCurrentUser(decoded));

  // Check for expired token
  const currentTime = Date.now() / 1000;
  if (decoded.exp < currentTime) {
    // Logout user
    store.dispatch(logoutUser());

    // Redirect to login
    window.location.href = '/login';
  }
}
class HomePage extends Component
{
  componentDidMount(){
    console.log(this.props.auth.isAuthenticated);
  }
    render(){
      var {
        isAuthenticated
      } = this.props.auth;
      return(
        <div>
          <Router>
            <div>
              <Switch>
                {this.props.auth.isAuthenticated===false ? (
                  <div>
                  <Route exact path='/' component={LogoutHome}/>
                  <Route  path='/Finance/Login' component={SignIn}/>
                  <Route  path='/Finance/AboutUs' component={AboutUs}/>
                  <Route  path='/Finance/ContactUs' component={ContactUs}/>
                  <Route  path='/Finance/SignUp' component={SignUp}/>
                  <Route  path='/Finance/Forgotpassword' component={Forgotpassword}/>
                  </div>
                  ) : (
                    <div>
                  <Route  path='/Finance/Home' component={Home}/>
                  </div>
                  )}
              </Switch>
            </div>
          </Router>
        </div>
      );
    }
}
function mapStateToProps(state){
  return{
    auth : state.auth
  };
}
export default connect(mapStateToProps)(HomePage);

Et l'avertissement ressemble à ceci:

index.js:2178 Warning: React does not recognize the `computedMatch` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `computedmatch` instead. If you accidentally passed it from a parent component, remove it from the DOM element.

Je ne comprends pas la météo, c'est un problème de cas ou quoi parce que je l'ai lu à plusieurs endroits mais des réponses différentes que j'obtiens. Ci-dessus collé est uniquement le composant de la page d'accueil.

De React doc

L'avertissement unknown-prop se déclenchera si vous essayez de rendre un élément DOM avec un accessoire qui n'est pas reconnu par React comme un attribut/propriété DOM légal. Vous devez vous assurer que vos éléments DOM ne ont des accessoires faux flottant autour.

À l'intérieur de <Swtich> composant, vous verrez la ligne ci-dessous.

React.cloneElement(child, { location, computedMatch: match })

Dans ce cas, le child est votre <div></div>, donc un accessoire non standard computedMatch est passé au nœud dom natif <div>, donc React vous donne un avertissement sain. Donc, en utilisant <> ou <Fragment> supprimera l'avertissement.

Je résous ce problème supprimer<div> tag à l'intérieur du tag. ou remplacer<div> avec <React.Fragment>.

dans ce cas :

import React,{Component} from "react";
import {BrowserRouter as Router, Switch, Route} from "react-router-dom";
import LogoutHome from './Logout_Home';
import SignIn from '../Components/SignIn';
import jwt_decode from 'jwt-decode';
import {setCurrentUser} from '../actions/authActions';
import SignUp from '../Components/SignUp';
import setAuthToken from '../util/setAuthToken';
import AboutUs from '../containers/AboutUs';
import store from '../store';
import {connect} from "react-redux";
// check for TOKEN
if (localStorage.jwtToken) {
  // Set auth token header auth
  setAuthToken(localStorage.jwtToken);
  // Decode token and get user info and exp
  const decoded = jwt_decode(localStorage.jwtToken);
  // Set user and isAuthenticated
  store.dispatch(setCurrentUser(decoded));

  // Check for expired token
  const currentTime = Date.now() / 1000;
  if (decoded.exp < currentTime) {
    // Logout user
    store.dispatch(logoutUser());

    // Redirect to login
    window.location.href = '/login';
  }
}
class HomePage extends Component
{
  componentDidMount(){
    console.log(this.props.auth.isAuthenticated);
  }
    render(){
      var {
        isAuthenticated
      } = this.props.auth;
      return(
        <div>
          <Router>
            <div>
              <Switch>
                {this.props.auth.isAuthenticated===false ? (
                  <React.Fragment>
                  <Route exact path='/' component={LogoutHome}/>
                  <Route  path='/Finance/Login' component={SignIn}/>
                  <Route  path='/Finance/AboutUs' component={AboutUs}/>
                  <Route  path='/Finance/ContactUs' component={ContactUs}/>
                  <Route  path='/Finance/SignUp' component={SignUp}/>
                  <Route  path='/Finance/Forgotpassword' component={Forgotpassword}/>
                  </React.Fragment>
                  ) : (
                    <React.Fragment>
                  <Route  path='/Finance/Home' component={Home}/>
                  </React.Fragment>
                  )}
              </Switch>
            </div>
          </Router>
        </div>
      );
    }
}
function mapStateToProps(state){
  return{
    auth : state.auth
  };
}
export default connect(mapStateToProps)(HomePage);
