这是我的入口点文件：

import React, { PropTypes } from 'react'
import ReactDOM from 'react-dom'
import { createStore, combineReducers } from 'redux'
import { Provider } from 'react-redux'
import createBrowserHistory from 'history/lib/createBrowserHistory'
import { Router, Route } from 'react-router'
import { syncReduxAndRouter, routeReducer } from 'redux-simple-router'
import reducers from './reducers'

import App from './containers/app.jsx'
import About from './about.jsx'
import Dashboard from './dashboard/index.jsx'

const reducer = combineReducers(Object.assign({}, reducers, {
    routing: routeReducer
}))
const store = createStore(reducer)
const history = createBrowserHistory()

syncReduxAndRouter(history, store)

const routes = {
  path: '/',
  component: App,
  childRoutes: [
    { path: 'about', component: About },
    { path: 'dashboard', component: Dashboard }
  ]
}

ReactDOM.render(
    <Provider store={store}>
        <Router routes={routes} history={history} />
    </Provider>,
    document.getElementById('app')
)

从我能收集到的信息来看，这似乎是相当标准的。但是，我对如何将道具从App例如Dashboard组件向下获取有点困惑。这是App组件：

import React, {PropTypes} from 'react'
import {bindActionCreators} from 'redux'
import {connect} from 'react-redux'
import {Link} from 'react-router'

import * as authActions from './../actions/auth'

class App extends React.Component {
    render() {
        return (
            <div>
                <h1>App</h1>
                <ul>
                    <li>
                        <Link to="/">Home</Link>
                    </li>
                    <li>
                        <Link to="/about">About</Link>
                    </li>
                    <li>
                        <Link to="/dashboard">Dashboard</Link>
                    </li>
                </ul>
                {this.props.children}
            </div>
        )
    }
}

App.propTypes = {
    authActions: PropTypes.object.isRequired,
    authState: PropTypes.object.isRequired
}

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

function mapDispatchToProps(dispatch) {
    return {
        authActions: bindActionCreators(authActions, dispatch)
    }
}

export default connect(mapStateToProps, mapDispatchToProps)(App)

抱歉，代码不是更简洁一点，但我特别试图将authState（从我的 Reducer）传递给Dashboard组件，我对它如何与 React Router 和库一起工作有点困惑redux-simple-router......

编辑：

我更改了Dashboard组件以将其包含在底部：

Dashboard.propTypes = {
    authActions: PropTypes.object.isRequired,
    authState: PropTypes.object.isRequired
}

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

function mapDispatchToProps(dispatch) {
    return {
        authActions: bindActionCreators(authActions, dispatch)
    }
}

export default connect(mapStateToProps, mapDispatchToProps)(Dashboard)

我现在可以访问 Redux 状态和操作。我不确定这是否是正确的方法，但它现在有效......

使用 react-router v1+，您可以使用以下命令访问当前最深路线上的道具：this.props.route.

<Route path='/' component={App}>
        <IndexRoute component={Home} />
        <Route path='about' component={About} />
        <Route path='dashboard' component={Dashboard} customprop="Hello, it's me" />
        <Route path="*" component={NoMatch} />
</Route>

在您的仪表板组件中：

this.props.route.customprop=>"Hello, it's me"

要访问当前路线树中的所有路线，您可以遍历this.props.routes（最深的路线是最后一条）。
