我正在尝试为我的 React 应用程序设置服务器端渲染，并且我正在尝试使用出色的react-routermodule来允许它处理非 js 情况（一些爬虫，当用户关闭了一些 js 时）原因）。但是，我遇到了麻烦。我一直在使用https://stackoverflow.com/a/28558545/3314701 上的出色回应作为各种指南，但我收到了一些奇怪的错误。我得到一个持续的Syntax Error努力使用时react.renderToString()。我是否错误地设置了服务器端渲染，遗漏了一些明显的东西，或者其他任何东西？

我的设置：

真正基本的 Express 服务器

require('babel/register');

var app = express();


// misc. express config...

var Router = require('react-router'),
    routes = require('../jsx/app').routes,
    React = require('react');


app.use(function(req, res, next) {
  var router = Router.create({location: req.url, routes: routes});
  router.run(function(Handler, state) {
    console.log(Handler);
    var html = React.renderToString(<Handler/>);
    return res.render('react_page', {html: html});
  });
});

顶级react<App/>组件

// Shims
require('intl');
require('es5-shim');

var React = require('react/addons'),
  Router = require('react-router'),
  Nav = require('./nav'),
  injectTapEventPlugin = require("react-tap-event-plugin"),


  window.React = React; // export for http://fb.me/react-devtools

// Intl
var ReactIntl = require('react-intl'),
  IntlMixin = ReactIntl.IntlMixin;

var Route = Router.Route,
  DefaultRoute = Router.DefaultRoute,
  NotFoundRoute = Router.NotFoundRoute,
  RouteHandler = Router.RouteHandler;


var App = React.createClass({
      mixins: [IntlMixin],

      getInitialState: function() {
        return {
          connected: false,
          loaded: false,
          user: true
        };
      },
      render: function() {
          return ( 
            <div className="container-fluid">
              <Nav/>
              <RouteHandler/>
              <Footer/>
            </div>
      );
  }

});

var routes = (
<Route name="Home" path="/" handler={App}>
    <DefaultRoute name="Welcome " handler={Welcome}/>
    <Route name="Bar" path="/bar" handler={Bar}>
    <Route name="foo" path="/foo" handler={Foo}></Route>
 </Route>
);

Router.run(routes, Router.HistoryLocation , function(Handler) {
  React.render(<Handler/>, document.getElementById('app'));
});

module.routes = routes;
