我使用 match 方法进行服务器端渲染，回调中的参数始终未定义。可能出了点问题，但已经整整一天了，我无法理解它。
这是我的服务器端渲染。
// Create location from the history module.
let location = createLocation(req.url);
match({Routes, location}, (error, redirectLocation, renderProps) => {
// TODO : Verify why this is always undefined
console.log('ERROR :: ', error)
console.log('REDIRECT LOCATION :: ', redirectLocation)
console.log('RENDER PROPS :: ', renderProps)
if (redirectLocation) {
res.redirect(redirectLocation.pathname + redirectLocation.search)
}
// TODO : Verify why this is breaking
//else if (error || !renderProps) {
// return console.log('Error while starting server :: ', error)
//}
else {
Transmit.renderToString(RoutingContext, renderProps).then(({reactString, reactData}) => {
console.log('REACT STRING :: ', reactString);
console.log('REACT DATA :: ', reactData);
let output = (
`<!doctype html>
<html lang="en-us" style="min-height:100vh; width: 100%; background-color: #eee;">
<head>
<meta charset="utf-8">
<title>react-isomorphic-pandora-app</title>
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/meyer-reset/2.0/reset.min.css">
<link rel="stylesheet" type="text/css" href="https://fonts.googleapis.com/css?family=Roboto:400,100,700">
</head>
<body>
<div id="react-root">${reactString}</div>
</body>
</html>`
);
var webserver = process.env.NODE_ENV === "production" ? "" : "//localhost:8080"
output = Transmit.injectIntoMarkup(output, reactData, [`${webserver}/dist/client.js`])
res.send(output)
}).catch((error) => {
res.send(error.stack).type("text/plain").code(500)
})
}
})
这是我的客户端。
import React from "react";
import ReactDOM from "react-dom";
import {Router} from "react-router";
import Transmit from "react-transmit";
import routes from "../views/Routes";
import {createHistory} from "history";
let reactRoot = window.document.getElementById("react-root");
let history = createHistory();
let location = history.createLocation();
const routerOption = {
routes: routes,
history: history,
location: location
}
Transmit.render(Router, routerOption, reactRoot);
if (process.env.NODE_ENV !== "production") {
if (!reactRoot.firstChild || !reactRoot.firstChild.attributes ||
!reactRoot.firstChild.attributes["data-react-checksum"]) {
console.error("Server-side React render was discarded. Make sure that your initial render does not contain any client-side code.");
}
}
这是我的路线。
import React from "react"
import {Router, Route} from "react-router"
import MenuView from "./Menu"
import DefaultView from "./Default"
import AnotherView from "./Another"
export default (
<Router component={MenuView}>
<Route path="/" component={DefaultView} />
<Route path="/another-view" component={AnotherView} />
</Router>
);
如有任何帮助，我们将不胜感激。 谢谢:)
编辑--------
这是我的 MenuView 组件中的代码。
class MenuView extends React.Component {
constructor(){
super()
this.menuItems = [
{
type: MenuItem.Types.SUBHEADER,
text: 'Menu sub header'
},
{
route: '/',
text: 'Home'
},
{
route: '/another-view',
text: 'Another view'
}
]
}
childContextTypes = {
muiTheme: React.PropTypes.object
};
getChildContext() {
return {
muiTheme: ThemeManager.getMuiTheme(DefaultTheme)
}
}
_getSelectedIndex = () => {
let currentItem;
for (let i = this.menuItems.length - 1; i >= 0; i--) {
currentItem = this.menuItems[i];
if (currentItem.route && this.props.history.isActive(currentItem.route)) return i;
}
}
_onLeftNavChange = (e, key, payload) => {
this.props.history.pushState(null, payload.route);
}
render () {
var style = {
paddingTop: '92px'
}
return (
<div>
<LeftNav
ref="leftNav"
menuItems={this.menuItems}
onChange={this._onLeftNavChange}
selectedIndex={this._getSelectedIndex()}
style={style}/>
<section className="content">
{this.props.children}
</section>
</div>
)
}
}
最佳答案
由于 Babel 5 与 Babel 6 和导出路由文件，它应该如下所示:
巴别塔 5:
Router.match({ routes:routes, location: req.url}, etc ...
巴别塔 6:
Router.match({ routes:routes.default, location: req.url}, etc ...
