将react-router和react-router-relay从v1.x更新到v2.x（位置“/”与任何路由不匹配）

2024-01-07

我正在尝试在我的应用程序中将react-router更新到v2.6，并将react-router-relay更新到v0.7，但我正在努力遵循更改日志来解决所有重大更改。我想我已经解决了所有更改，但仍然无法使其发挥作用。

警告：[react-router] 位置“/”与任何路由不匹配

这是我为应对这些变化所做的一步一步的指南。首先我更新了 npm 模块。

我之前的 package.json 一切正常：

"dependencies": {
    "babel-polyfill": "^6.9.1",
    "babel-runtime": "^6.9.2",
    "graphiql": "0.7.3",
    "graphql": "^0.6.2",
    "history": "1.13.1",
    "isomorphic-fetch": "^2.1.1",
    "react": "^15.2.1",
    "react-addons-shallow-compare": "^15.2.1",
    "react-dom": "^15.2.1",
    "react-loader": "^2.0.0",
    "react-relay": "^0.9.2",
    "react-router": "1.0.0-rc3",
    "react-router-relay": "^0.7.0",
    "superagent": "^1.2.0"
  },
  "devDependencies": {
    "babel-core": "^6.11.4",
    "babel-eslint": "^6.1.2",
    "babel-jest": "^13.2.2",
    "babel-loader": "^6.2.4",
    "babel-plugin-add-module-exports": "^0.2.1",
    "babel-plugin-transform-runtime": "^6.9.0",
    "babel-preset-es2015": "^6.9.0",
    "babel-preset-react": "^6.11.1",
    "babel-preset-stage-0": "^6.5.0",
    "babel-preset-stage-1": "^6.5.0",
    "babel-preset-stage-2": "^6.11.0",
    "babel-relay-plugin": "^0.9.2",
    "jest-cli": "^12.1.1",
    "react-addons-test-utils": "^15.2.1",
    "webpack": "^1.13.1"
  },

我的新 package.json 出现错误：

"dependencies": {
    "babel-polyfill": "^6.9.1",
    "babel-runtime": "^6.9.2",
    "graphiql": "0.7.3",
    "graphql": "^0.6.2",
    "isomorphic-fetch": "^2.1.1",
    "react": "^15.2.1",
    "react-addons-shallow-compare": "^15.2.1",
    "react-dom": "^15.2.1",
    "react-loader": "^2.0.0",
    "react-relay": "^0.9.2",
    "react-router": "^2.6.0",
    "react-router-relay": "^0.13.3",
    "superagent": "^1.2.0"
  },
  "devDependencies": {
    "babel-core": "^6.11.4",
    "babel-eslint": "^6.1.2",
    "babel-jest": "^14.0.0",
    "babel-loader": "^6.2.4",
    "babel-plugin-add-module-exports": "^0.2.1",
    "babel-plugin-transform-runtime": "^6.9.0",
    "babel-preset-es2015": "^6.9.0",
    "babel-preset-react": "^6.11.1",
    "babel-preset-stage-0": "^6.5.0",
    "babel-preset-stage-1": "^6.5.0",
    "babel-preset-stage-2": "^6.11.0",
    "babel-relay-plugin": "^0.9.2",
    "jest-cli": "^12.1.1",
    "react-addons-test-utils": "^15.2.1",
    "webpack": "^1.13.1"
  },

我删除了历史模块，因为它现在是反应路由器的直接依赖项。安装最新模块后，我重新加载页面并收到以下错误：

Error 1:

警告：[react-router] 看来您已经提供了一个已弃用的历史对象<Router/>，请使用 React Router 提供的历史记录import { browserHistory } from 'react-router' or import { hashHistory } from 'react-router'。如果您使用自定义历史记录，请使用以下命令创建它useRouterHistory, see https://github.com/reactjs/react-router/blob/master/upgrade-guides/v2.0.0.md#using-history-with-router https://github.com/reactjs/react-router/blob/master/upgrade-guides/v2.0.0.md#using-history-with-router了解详情。

Error 2:

警告：失败的上下文类型：无效的 prop/contextrelay供应给Relay(App)， 预期的undefined是一个符合RelayEnvironment界面。

in Router

Error 3:

警告：失败的上下文类型：必需的上下文route没有指定在Relay(App).

Error 4:

未捕获的不变违规：RelayContainer：Relay(App)使用无效的中继上下文进行渲染undefined。确保relayReact 上下文上的属性符合RelayEnvironment界面。

第一个错误提供了一个指向 React-router 升级指南的便捷链接，因此我按照它进行操作并相应地更新了我的 app.js 文件。

在我进行更改之前，它看起来是这样的：

import babelPolyfill from 'babel-polyfill';
import React from 'react';
import ReactDOM from 'react-dom';
import ReactRouterRelay from 'react-router-relay';
import Loader from 'react-loader';
import { Router, Route } from 'react-router';
import createBrowserHistory from 'history/lib/createBrowserHistory';

import WelcomeQueries from './queries/WelcomeQueries';
import AppQueries from './queries/AppQueries';
import LandingQueries from './queries/LandingQueries';

import App from './components/app';
import Landing from './components/landing';

import './relay';

const renderProps = {
  renderLoading: () => <Loader />,
};

ReactDOM.render((
  <Router history={createBrowserHistory()} createElement={ReactRouterRelay.createElement}>
    <Route component={App} queries={AppQueries} {...renderProps}>
      <Route path="/myapp" component={Landing} queries={LandingQueries} {...renderProps} />
    </Route>
    <Route path="/myapp/tracks" component={Welcome} queries={WelcomeQueries} {...renderProps}/>
  </Router>
), document.getElementById('myapp-body'));

尝试1

使用 2.x 的更新指南，我已将 app.js 文件更改为使用自定义历史记录像这样：

import babelPolyfill from 'babel-polyfill';
import React from 'react';
import ReactDOM from 'react-dom';
import ReactRouterRelay from 'react-router-relay';
import Loader from 'react-loader';

import { Router, Route, useRouterHistory } from 'react-router'
import { createHashHistory } from 'history'

import WelcomeQueries from './queries/WelcomeQueries';
import AppQueries from './queries/AppQueries';
import LandingQueries from './queries/LandingQueries';

import App from './components/app';
import Landing from './components/landing';

import './relay';

const renderProps = {
  renderLoading: () => <Loader />,
};

const appHistory = useRouterHistory(createHashHistory)({ queryKey: false })

ReactDOM.render((
  <Router history={appHistory} createElement={ReactRouterRelay.createElement}>
    <Route component={App} queries={AppQueries} {...renderProps}>
      <Route path="/myapp" component={Landing} queries={LandingQueries} {...renderProps} />
    </Route>
    <Route path="/myapp/tracks" component={Welcome} queries={WelcomeQueries} {...renderProps}/>
  </Router>
), document.getElementById('myapp-body'));

然后，这会在浏览器中出现以下错误：

Error 5

警告：[react-router] 位置“/”与任何路由不匹配

我相信这就是我想要的解决方案..但是我不确定，所以我也尝试去浏览器 (HTML5 PushState) 历史记录方式并尝试了以下更改：

尝试2

import babelPolyfill from 'babel-polyfill';
import React from 'react';
import ReactDOM from 'react-dom';
import ReactRouterRelay from 'react-router-relay';
import Loader from 'react-loader';

import { Router, Route, browserHistory } from 'react-router'

import WelcomeQueries from './queries/WelcomeQueries';
import AppQueries from './queries/AppQueries';
import LandingQueries from './queries/LandingQueries';

import App from './components/app';
import Landing from './components/landing';

import './relay';

const renderProps = {
  renderLoading: () => <Loader />,
};

const appHistory = useRouterHistory(createHashHistory)({ queryKey: false })

ReactDOM.render((
  <Router history={browserHistory} createElement={ReactRouterRelay.createElement}>
    <Route component={App} queries={AppQueries} {...renderProps}>
      <Route path="/myapp" component={Landing} queries={LandingQueries} {...renderProps} />
    </Route>
    <Route path="/myapp/tracks" component={Welcome} queries={WelcomeQueries} {...renderProps}/>
  </Router>
), document.getElementById('myapp-body'));

加载此内容时，我收到错误 2、3 和 4。我认为尝试 1 是正确的方法，但我不知道这个错误意味着什么，谷歌搜索它，给了我大量答案（1 https://stackoverflow.com/questions/34837138/react-router-location-did-not-match-any-routes, 2 https://github.com/reactjs/react-router/issues/2117，这将我链接到3 https://github.com/reactjs/react-router/blob/master/upgrade-guides/v1.0.0.md#links乃至4 https://github.com/reactjs/react-router/issues/3541与 IndexRoute），我尝试过，但没有一个答案有效。

我的 App.js 文件如下所示，仅供参考：

import React from 'react';
import Relay from 'react-relay';
import Top from './top';

export class App extends React.Component {
  render() {
    return (
      <div>
        <Top viewer={this.props.viewer}/>
        {this.props.children}
      </div>
    );
  }
}

export default Relay.createContainer(App, {
  fragments: {
    viewer: () => Relay.QL`
      fragment on Viewer {
        ${Top.getFragment('viewer')}
      }
    `,
  },
});

我不能 100% 确定这是否是原因，但我知道反应路由器 v2.0.0-rc6 https://github.com/reactjs/react-router/blob/master/CHANGES.md#v200-rc6发生了重大变化，顶级路由器导出被删除，但我真的不知道这对我意味着什么？那我就不能再用路由器了吗？如果是这样，我该怎么办？

经过几天的研究和反复试验，我放弃了，希望这里有人能提供帮助。任何正确方向的指示将不胜感激。


终于得到了这个问题的答案，并且必须添加以下更改以使我的代码再次工作：

import babelPolyfill from 'babel-polyfill';
import React from 'react';
import ReactDOM from 'react-dom';
import Loader from 'react-loader';

import Relay from 'react-relay';
import useRelay from 'react-router-relay';
import { Router, Route, IndexRoute, browserHistory } from 'react-router';
import applyRouterMiddleware from 'react-router/lib/applyRouterMiddleware';

import WelcomeQueries from './queries/WelcomeQueries';
import AppQueries from './queries/AppQueries';
import LandingQueries from './queries/LandingQueries';

import App from './components/app';
import Landing from './components/landing';

import './relay';

ReactDOM.render((
  <Router 
    history={browserHistory} 
    render={applyRouterMiddleware(useRelay)} 
    environment={Relay.Store}>

    <Route 
      component={App} 
      queries={AppQueries} 
      render={({ props }) => props ? <App {...props} /> : <Loader />}>

      <Route 
        path="/myapp" 
        component={Landing} 
        queries={LandingQueries} 
        render={({ props }) => props ? <Landing {...props} /> : <Loader />} />
    </Route>

    <Route 
      path="/myapp/tracks" 
      component={Welcome} 
      queries={WelcomeQueries} 
      render={({ props }) => props ? <Welcome {...props} /> : <Loader />} />

  </Router>
), document.getElementById('myapp-body'));

也许这会帮助别人:)
