我正在尝试通过express从我的服务器提供React服务。
我遇到localhost:3000时遇到的错误是:
TypeError: (0 , _reactRouter.match) is not a function at /Users/chris/code/affordance/app/server.js:20:3
这是执行此操作的server.js文件:
import path from 'path'; import { Server } from 'http'; import Express from 'express'; import React from 'react'; import { renderToString } from 'react-dom/server'; import { match, RouterContext } from 'react-router'; import routes from './routes'; import NotFoundPage from './components/NotFoundPage'; // Initialize the express server, and tell it to use ejs const app = new Express(); const server = new Server(app); app.set('view engine', 'ejs'); app.set('views', path.join(__dirname, 'views')); // Tell express where the static assets are app.use(Express.static(path.join(__dirname, 'static'))); app.get('*', (req, res) => { match( { routes, location: req.url }, (err, redirectLocation, renderProps) => { if (err) { return res.status(500).send(err.message); } if (redirectLocation) { return res.redirect(302, redirectLocation.pathname + redirectLocation.search); } let markup; if (renderProps) { markup = renderToString(<RouterContext {...renderProps}/>); } else { markup = renderToString(<NotFoundPage/>); res.status(404); } return res.render('index', { markup }); } ); }); 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}]`); });
据我所知,我正在将其导入的方式与其他地方(例如here)的使用方式相同。
我错过了一些东西,我不知道接下来该怎么猜。我究竟做错了什么?
ps-react-router版本为4.0.0,匹配文档在这里
如果您在v4之前使用了react router,那么您的代码看起来是正确的,但是react-router v4在整个代码库中都有重大更改,包括服务器渲染方法。在v4中,有一个专门用于服务器渲染的新组件- StaticRouter。
StaticRouter
您的代码在v4中应如下所示:
import path from "path"; import { Server } from "http"; import Express from "express"; import React from "react"; import { renderToString } from "react-dom/server"; import { StaticRouter } from "react-router"; import App from "./app"; import NotFoundPage from "./components/NotFoundPage"; // Initialize the express server, and tell it to use ejs const app = new Express(); const server = new Server(app); app.set("view engine", "ejs"); app.set("views", path.join(__dirname, "views")); // Tell express where the static assets are app.use(Express.static(path.join(__dirname, "static"))); app.get("*", (req, res) => { // This context object contains the results of the render const context = {}; const html = renderToString( <StaticRouter location={req.url} context={context}> <App /> </StaticRouter> ); res.status(200).send(html); }); 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}]`); });
这是EbayTech的一篇非常好的带注释的文章,显示了如何使用StaticRouter(用于服务器)和BrowserRouter(用于客户端)设置应用程序
