根据Rajesh Naroth回答使用带或不带路由器的组件。

class Index extends React.Component {

  constructor(props) {
    super(props);
  }
  render() {
    const foo = (this.props.route) ? this.props.route.foo : this.props.foo;
    return (
      <h1>
        Index - {foo}
      </h1>
    );
  }
}

var routes = (
  <Route path="/" foo="bar" component={Index}/>
);

或者你可以这样做:

export const Index = ({foo, route}) => {
  const content = (foo) ? foo : (route) ? route.foo : 'No content found!';
  return <h1>{content}</h1>
};

React-router v4 alpha

现在有了一种新的方法，尽管和之前的方法很相似。

import { Match, Link, Miss } from 'react-router';
import Homepage from './containers/Homepage';

const route = {
    exactly: true,
    pattern: '/',
    title: `${siteTitle} - homepage`,
    component: Homepage
  }

<Match { ...route } render={(props) => <route.component {...props} />} />

附注:这只适用于alpha版本，并且在v4 alpha发布后被删除。在v4 latest中，同样是带有路径和精确props的。

React-lego是一个示例应用程序，它在react-router-4分支的routes.js中包含了这样做的代码

使用自定义路由组件，这在React Router v3中是可能的。

var Dashboard = require('./Dashboard');
var Comments = require('./Comments');
var routes = (
  <Route path="/" handler={Index}>
    <MyRoute myprop="value" path="comments" handler={Comments}/>
    <DefaultRoute handler={Dashboard}/>
  </Route>
);

对于<MyRoute>组件代码，它应该类似于:

import React from 'react';
import { Route } from 'react-router';
import { createRoutesFromReactChildren } from 'react-router/lib//RouteUtils';

const MyRoute = () => <div>&lt;MyRoute&gt; elements are for configuration only and should not be rendered</div>;

MyRoute.createRouteFromReactElement = (element, parentRoute) => {
    const { path, myprop } = element.props;
    // dynamically add crud route
    const myRoute = createRoutesFromReactChildren(
        <Route path={path} />,
        parentRoute
    )[0];
    // higher-order component to pass myprop as resource to components
    myRoute.component = ({ children }) => (
        <div>
            {React.Children.map(children, child => React.cloneElement(child, { myprop }))}
        </div>
    );
    return myRoute;
};

export default MyRoute;

这可能是在cookie处理程序中使用react-router-dom的最佳方式

在index.js

import React, { Component } from 'react'
import {Switch,Route,Redirect} from "react-router-dom"
import {RouteWithLayout} from "./cookieCheck"

import Login from "../app/pages/login"
import DummyLayout from "../app/layouts/dummy"
import DummyPage from "../app/pages/dummy" 

export default ({props})=>{
return(
    <Switch>
        <Route path="/login" component={Login} />
        <RouteWithLayout path="/dummy" layout={DummyLayout} component={DummyPage} 
        {...props}/>
        <Redirect from="/*" to="/login" />
    </Switch>
  )
}

并使用cookie检查

import React , {createElement} from 'react'
import {Route,Redirect} from "react-router-dom"
import {COOKIE,getCookie} from "../services/"

export const RouteWithLayout = ({layout,component,...rest})=>{
    if(getCookie(COOKIE)==null)return <Redirect to="/login"/>
        return (
        <Route {...rest} render={(props) =>
            createElement(layout, {...props, ...rest}, createElement(component, 
      {...props, ...rest}))
       }
      />
    )
}

使用ES6，你可以让组件包装内联:

<路由路径= " / "组件={()= > <应用myProp = {someValue} / >} >

如果你需要通过孩子:

<路由路径="/"组件={(道具)=> <App myProp={someValue}>{道具。孩子}< /应用程序>}>

只是ColCh回答的一个后续问题。抽象一个组件的包装是很容易的:

var React = require('react');

var wrapComponent = function(Component, props) {
  return React.createClass({
    render: function() {
      return React.createElement(Component, props);
    }
  });
};

<Route path="comments" handler={wrapComponent(Comments, {myprop: value})}/>

我还没有测试这个解决方案，所以任何反馈都很重要。

需要注意的是，使用这种方法，任何通过Router发送的道具(比如params)都会被覆盖/删除。
