如何使用React Router 4配置专用路由

Question

I have the following code for private route component.

import React from 'react';
import {Route, Redirect} from 'react-router-dom';
import {connect} from 'react-redux';

class PrivaetRoute extends React.Component {

    render() {
        const {component: Component, ...rest} = this.props;

        return (
            <Route
                {...rest}
                render={props => this.props.loggedIn ? (
                    <Component {...props}/>
                ) : (
                    <Redirect
                        to={{
                            pathname: '/',
                            state: {from: this.props.location},
                        }}
                    />
                )}
            />
        )
    }
}

function mapStateToProps(state) {
    return {
        loggedIn: state.loggedIn
    }
}

export default connect(mapStateToProps)(PrivaetRoute);

and I have the following code for the app component that renders different routes

import React from 'react';
import {BrowserRouter, Route, Switch} from 'react-router-dom';
import Reboot from 'material-ui/Reboot';

/**
 * Local
 * */

import IndexPage from '../pages/Index';
import DashboardPage from '../pages/Dashboard';
import PrivateRoute from '../containers/PrivateRoutes';

export default class App extends React.Component {

    render() {
        return (
            <div>
                <BrowserRouter>
                    <div>
                        <Reboot/>
                        <Switch>
                            <Route exact path="/" component={IndexPage}/>
                            <PrivateRoute path="/dashboard" component={DashboardPage}/>
                        </Switch>
                    </div>
                </BrowserRouter>
            </div>
        );
    }
}

How I have designed login system is that my redux action alters the loggedIn state to be true when authentication is complete. I have checked using chrome developer tool that loggedIn state is indeed being set to loggedIn:true ; however, when I change the url to /dashboard all the states refreshes (even the redux states) and I get redirected to / . What am I doing wrong?

** edit redux container

import React from 'react';
import ReactDOM from 'react-dom';
import {Provider} from 'react-redux';
import {createStore, applyMiddleware} from 'redux';
import reduxThunk from 'redux-thunk';
import {composeWithDevTools} from 'redux-devtools-extension';

import App from './components/App';
import reducers from './reducers';

const store = createStore(reducers, {}, composeWithDevTools(applyMiddleware(reduxThunk)));

ReactDOM.render(
    <Provider store={store}>
        <App />
    </Provider>,
    document.querySelector('#root')
);

Answer 1

You should use Redux

You can read about it here .

Why you should use Redux?

Because Redux serves as a global state container, it means no matter which page you go, the state will not be reset.

How to use Redux with React-Router correctly?

Just remember one thing, Redux should be the parent of React-Router.
So it should look something like this

<Provider>
    <Router>
        <YourApp/>
    </Router>
</Provider>

FYI: Provider is the state container of Redux.

If you make <Router> as the parent of <Provider> , you'll be facing the same problem again.

Hope it helps.

Answer 2

It wasn't at all to do with the route settings.

I was using combineReducers function and I did not realize that it wraps all the states into a parent object so I had to access its key before accessing the actual object that I wanted to access.
