我有以下应用:
客户端
index.js
import React from "react";
import ReactDOM from "react-dom";
import Root from "./containers/Root";
import configureStore from "./store/configureStore";
import { browserHistory } from "react-router";
import { loginUserSuccess } from "./actions/auth";
import { syncHistoryWithStore } from "react-router-redux";
const target = document.getElementById("root");
const store = configureStore(browserHistory, window.__INITIAL_STATE__);
// Create an enhanced history that syncs navigation events with the store
const history = syncHistoryWithStore(browserHistory, store)
const node = (
<Root store={store} history={history} />
);
let token = localStorage.getItem("token");
if (token !== null) {
store.dispatch(loginUserSuccess(token));
}
ReactDOM.render(node, target);
Root.js
import React from "react";
import {Provider} from "react-redux";
import AppRouter from "../routes/appRouter";
export default class Root extends React.Component {
static propTypes = {
store: React.PropTypes.object.isRequired,
history: React.PropTypes.object.isRequired
};
render () {
return (
<Provider store={this.props.store}>
<AppRouter history={this.props.history}>
</AppRouter>
</Provider>
);
}
}
AppRouter(routes / appRouter.js
import React from "react";
import routes from "./routes";
import { Router } from "react-router";
export default (
<Router routes={routes} history={this.props.history}></Router>
)
路线(routes / routes.js)
import React from "react";
import {Route, IndexRoute} from "react-router";
import { App } from "../containers";
import {HomeView, LoginView, ProtectedView, NotFoundView} from "../views";
import {requireAuthentication} from "../components/core/AuthenticatedComponent";
export default (
<Route path='/' component={App} name="app" >
<IndexRoute component={requireAuthentication(HomeView)}/>
<Route path="login" component={LoginView}/>
<Route path="protected" component={requireAuthentication(ProtectedView)}/>
<Route path="*" component={NotFoundView} />
</Route>
)
requireAuthentication(/component/core/AuthenticatedComponent.js)
import React from "react";
import {connect} from "react-redux";
import { push } from "react-router-redux";
export function requireAuthentication(Component) {
class AuthenticatedComponent extends React.Component {
componentWillMount () {
this.checkAuth(this.props.isAuthenticated);
}
componentWillReceiveProps (nextProps) {
this.checkAuth(nextProps.isAuthenticated);
}
checkAuth (isAuthenticated) {
if (!isAuthenticated) {
let redirectAfterLogin = this.props.location.pathname;
this.props
.dispatch(push(`/login?next=${redirectAfterLogin}`));
}
}
render () {
return (
<div>
{this.props.isAuthenticated === true
? <Component {...this.props}/>
: null
}
</div>
)
}
}
const mapStateToProps = (state) => ({
token: state.auth.token,
userName: state.auth.userName,
isAuthenticated: state.auth.isAuthenticated
});
return connect(mapStateToProps)(AuthenticatedComponent);
}
configureStore.js
import rootReducer from "../reducers";
import thunkMiddleware from "redux-thunk";
import {createStore, applyMiddleware, compose} from "redux";
import {routerMiddleware} from "react-router-redux";
import {persistState} from "redux-devtools";
import createLogger from "redux-logger";
import DevTools from "../dev/DevTools";
const loggerMiddleware = createLogger();
const enhancer = (history) =>
compose(
// Middleware you want to use in development:
applyMiddleware(thunkMiddleware, loggerMiddleware, routerMiddleware(history)),
// Required! Enable Redux DevTools with the monitors you chose
DevTools.instrument(),
persistState(getDebugSessionKey())
);
function getDebugSessionKey() {
if(typeof window == "object") {
// You can write custom logic here!
// By default we try to read the key from ?debug_session=<key> in the address bar
const matches = window.location.href.match(/[?&]debug_session=([^&#]+)\b/);
return (matches && matches.length > 0)? matches[1] : null;
}
return;
}
export default function configureStore(history, initialState) {
// Add the reducer to your store on the `routing` key
const store = createStore(rootReducer, initialState, enhancer(history))
if (module.hot) {
module
.hot
.accept("../reducers", () => {
const nextRootReducer = require("../reducers/index");
store.replaceReducer(nextRootReducer);
});
}
return store;
}
服务器
server.js
import path from "path";
import { Server } from "http";
import Express from "express";
import React from "react";
import {Provider} from "react-redux";
import { renderToString } from "react-dom/server";
import { match, RouterContext } from "react-router";
import routes from "./src/routes/routes";
import NotFoundView from "./src/views/NotFoundView";
import configureStore from "./src/store/configureStore";
import { browserHistory } from "react-router";
// import { syncHistoryWithStore } from "react-router-redux";
// initialize the server and configure support for ejs templates
const app = new Express();
const server = new Server(app);
app.set("view engine", "ejs");
app.set("views", path.join(__dirname, "./"));
// define the folder that will be used for static assets
app.use("/build", Express.static(path.join(__dirname, "build")));
// // universal routing and rendering
app.get("*", (req, res) => {
const store = configureStore(browserHistory);
match(
{ routes, location: req.url },
(err, redirectLocation, renderProps) => {
// in case of error display the error message
if (err) {
return res.status(500).send(err.message);
}
// in case of redirect propagate the redirect to the browser
if (redirectLocation) {
return res.redirect(302, redirectLocation.pathname + redirectLocation.search);
}
// generate the React markup for the current route
let markup;
if (renderProps) {
// if the current route matched we have renderProps
// markup = renderToString(<Provider store={preloadedState} {...renderProps}/>);
markup = renderToString(
<Provider store={store} >
<RouterContext {...renderProps} />
</Provider>
);
} else {
// otherwise we can render a 404 page
markup = renderToString(<NotFoundView />);
res.status(404);
}
// render the index template with the embedded React markup
const preloadedState = store.getState()
return res.render("index", { markup, preloadedState });
}
);
});
// start the server
const port = process.env.PORT || 3000;
const env = process.env.NODE_ENV || "production";
server.listen(port, err => {
if (err) {
return console.error(err);
}
console.info(`Server running on http://localhost:${port} [${env}]`);
});
我不知道我是否在服务器端正确初始化了我的商店。
我怎么知道这个?因为renderProps
始终为null,因此返回NotFoundView
。
但是我做了一些修改,因为我知道我的路线被错误地初始化了。
这使我在服务器端使用我的configureStore(...)
(我在客户端使用它并且它正在工作)。
现在我收到以下错误:
TypeError:无法读取属性&#39; push&#39;未定义的
此错误发生在以下行中的AuthenticatedComponent
:
this.props
.dispatch(push(`/login?next=${redirectAfterLogin}`));
这很奇怪,因为它在客户端和服务器端工作,它只会抛出此错误。
有什么想法吗?
PS
我是否通过在客户端和服务器中使用相同的Routes.js
来正确执行此操作?
我的configureStore(...)
也一样吗?
我看到的所有示例中,他们使用不同的方法创建服务器端存储,createStore
来自redux
而不是客户端的存储配置。
PS2
我现在明白push
可能无法在服务器上运行,只能在客户端运行(对吗?)。有没有解决方法呢?
PS3
我遇到的问题正在发生,因为我正在将<Router />
呈现到服务器中,而我的routes.js
应该只包含<Route />
个节点。
但是,过了一段时间后,我发现不应该在服务器中配置历史记录,我只是配置了我的商店并将其传递给正在呈现的<Provider />
。
但现在我需要编译我的JSX并抛出:
Error: Module parse failed: D:\VS\Projects\Tests\OldDonkey\OldDonkey.UI\server.js Unexpected token (46:20)
You may need an appropriate loader to handle this file type.
