我试图在我的反应应用程序中实现服务器端呈现 . 我无法使用react，react-dom和react-router的服务器实现来访问DOM . 我要么“浏览器历史记录需要DOM”错误 .
所以我的猜测是我在服务器或客户端包装组件的方式有问题 .
我将分享我的结构和本练习中涉及的重要文件！
server.js

import rootReducer from "../src/reducers/index";
import routes from '../src/routes/routes';
const app = express();
app.use(express.static('public'));
app.get('*', (req,res)=>{
const axiosMiddlewareOptions = {
interceptors: {
request: [
(action, config) => {
if (sessionStorage.token) {
config.headers['Authorization'] = 'Token '+ sessionStorage.token;
}
return config
}
]
}
};
const history = createBrowserHistory();
const appRouterMiddleware = routerMiddleware(history);
const createStoreWithMiddleware =
applyMiddleware(multiClientMiddleware(api, axiosMiddlewareOptions),
appRouterMiddleware)(createStore);
const store = createStoreWithMiddleware(rootReducer, {},
window.devToolsExtension ? window.devToolsExtension() : f => f);
const context = {};
const html = renderToString(
<Provider store={store}>
<StaticRouter location={req.url} context={context}>
<ConnectedRouter history={history} children={routes}/>
</StaticRouter>

);
res.send(`

我还没有时间去测试它，但是ConnectRouter有一个名为isSSR的道具，它可以阻止订阅仅限DOM的东西 . （https://github.com/ReactTraining/react-router/blob/master/packages/react-router-redux/modules/ConnectedRouter.js）
我的猜测是你现在可以用它来使用
memoryHistory. （https://github.com/ReactTraining/react-router/blob/master/packages/react-router/docs/api/history.md）将尝试在周末获得一个示例应用程序 .
使用createMemoryHistory（）解决了错误
const history = createMemoryHistory（）;
