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;

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>
};

使用如下所示的解决方案，它可以在v3.2.5中工作。

<Route
  path="/foo"
  component={() => (
    <Content
      lang="foo"
      meta={{
        description: lang_foo.description
      }}
    />
  )}
/>

or

<Route path="/foo">
  <Content
    lang="foo"
    meta={{
      description: lang_foo.description
    }}
  />
</Route>

在react-router-v3中，我没有找到任何工作解决方案，所以我做了一个很大的权衡，使用类继承而不是道具。

例如:

class MyComments extends Comments{
  constructor(props) {
    super(props);
    this.myProp = myValue;
  }
}

并且，你在路由器的组件中使用MyComments而不需要道具。

然后，你可以用这个。myProp在componentDidMount()函数中获取myValue;

更新

自新版本以来，可以直接通过Route组件传递道具，而不使用Wrapper。例如，通过使用渲染道具。

组件:

class Greeting extends React.Component {
  render() {
    const {text, match: {params}} = this.props;

    const {name} = params;

    return (
      <React.Fragment>
        <h1>Greeting page</h1>
        <p>
          {text} {name}
        </p>
      </React.Fragment>
    );
  }
}

用法:

<Route path="/greeting/:name" render={(props) => <Greeting text="Hello, " {...props} />} />

Codesandbox例子

旧版本

我更喜欢的方法是包装Comments组件，并将包装器作为路由处理程序传递。

这是应用更改后的示例:

var Dashboard = require('./Dashboard');
var Comments = require('./Comments');

var CommentsWrapper = React.createClass({
  render: function () {
    return (
      <Comments myprop="myvalue"/>
    );
  }
});

var Index = React.createClass({
  render: function () {
    return (
      <div>
        <header>Some header</header>
        <RouteHandler/>
      </div>
    );
  }
});

var routes = (
  <Route path="/" handler={Index}>
    <Route path="comments" handler={CommentsWrapper}/>
    <DefaultRoute handler={Dashboard}/>
  </Route>
);

ReactRouter.run(routes, function (Handler) {
  React.render(<Handler/>, document.body);
});
