我正在尝试使用 react 和 react-router-dom 进行服务器端渲染我之前已经这样做过，但是对于新版本，它会抛出一个错误你不应该在路由器之外使用 Switch 我认为这是版本冲突，但是否有解决方案(react-router-config - You should not use outside a (it is inside a Router!))。
服务器.js
import express from 'express';
import React from 'react';
import ReactDOMServer from 'react-dom/server';
import App from '../client/src/AppRoutes';
import { StaticRouter } from 'react-router-dom';
import { renderRoutes } from 'react-router-config'
const app = express();
app.get('*', (req, res) => {
const routerContext = {};
res.send(`
<!doctype html>
<html lang="en">
<head>SSR</head>
<body>
<div id="root">${ReactDOMServer.renderToString(
<StaticRouter location={req.url} context={routerContext}>
<div>{renderRoutes(App)}</div>
</StaticRouter>
)}</div>
<!-- <script src="/dist/main.js"></script>-->
</body>
</html>
`);
});
app.listen(3000, (error) => {
if (error) {
return console.log('something bad happened', error);
}
console.log("listening on " + 3000 + "...");
});
AppRoutes.js
import PageA from './Container/PageA';
import PageB from './Container/PageB';
import Home from './Container/Home'
import MainPage from './Container/MainPage';
export default [
{
...MainPage,
routes:[
{
...Home,
path:'/',
exact:true
},
{
...PageA,
path:'/a',
exact:true
},
{
...PageB,
path:'/b',
exact:true
}
]
}
]

最佳答案
快速修复:
- 删除您的
node_modules - 将
"react-router": "^5.0.1"添加到您的package.json - 使用
npm install重新安装。
确保 react-router, react-router-config, react-router-dom 是同一个版本。
怎么了？
当我尝试重现你的错误时，我发现问题中你的 package.json 缺少 react-router 依赖，这让我无法启动服务器。
从你的故事来看，我猜你的 node_modules 中有另一个版本的 react-router，它与 react-router- 不同步配置 和 react-router-dom 版本 5.0.1。
所以我尝试重现这个问题:
"react-router": "^4.3.0",
"react-router-config": "^5.0.1",
"react-router-dom": "^5.0.1"
这将导致您提到的问题。
