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>

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);
});

你也可以使用RouteHandler mixin来避免包装器组件，更容易地将父类的状态作为道具传递下去:

var Dashboard = require('./Dashboard');
var Comments = require('./Comments');
var RouteHandler = require('react-router/modules/mixins/RouteHandler');

var Index = React.createClass({
      mixins: [RouteHandler],
      render: function () {
        var handler = this.getRouteHandler({ myProp: 'value'});
        return (
            <div>
                <header>Some header</header>
                {handler}
           </div>
        );
  }
});

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

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

这是我想出的最干净的解决方案(React Router v4):

<Route
  path="/"
  component={props => <MyComponent {...props} foo="lol" />}
/>

MyComponent仍然有道具。火柴和道具。位置，并有道具。Foo === "lol"。

用一个无状态的函数组件包装它:

<Router>
  <Route 
    path='/' 
    component={({children}) => 
      <MyComponent myProp={'myVal'}>{children}</MyComponent/>
    }/>
</Router>

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>
};
