从v1.x升级到v2.x的路由器中继(位置"/“与任何路由不匹配)

Question

我正试图在我的应用程序中更新react路由器到v2.6和react路由器中继到v0.7，但是我很难跟随变更来处理所有的破坏变化。我想我已经解决了所有的变化，但我还是不能让它发挥作用。

警告: routes路由器位置"/“与任何路由不匹配

下面是我为解决这些变化所做的一步一步的指导。首先，我更新了国家预防机制模块。

我以前的package.json，在那里一切都很好：

"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，在那里我会发现错误：

"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，因为它现在是一个反应路由器的直接依赖。一旦我安装了最新的模块，我就重新加载我的页面并得到以下错误：

错误1:

警告: React路由器如果您正在使用自定义历史记录，请使用useRouterHistory创建它，有关详细信息，请参阅https://github.com/reactjs/react-router/blob/master/upgrade-guides/v2.0.0.md#using-history-with-router。

错误2:

警告:失败的上下文类型:向Relay(App)提供的无效的Relay(App)/ context undefined，期望undefined是一个符合RelayEnvironment接口的对象。 在中继(应用程序)中(由RouterContext创建)在路由器中的RouterContext(由路由器创建)

错误3:

警告:失败的上下文类型:必需的上下文route没有在Relay(App)中指定。 在中继(应用程序)中(由RouterContext创建)在路由器中的RouterContext(由路由器创建)

错误4:

不变体冲突: RelayContainer：Relay(App)是用无效的中继上下文undefined呈现的。确保React上下文上的relay属性符合RelayEnvironment接口。

第一个错误给出了一个方便的链接到升级指南的反应路由器，所以我遵循它和更新我的app.js文件相应。

在进行更改之前，它看起来如下：

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，我将app.js文件更改为使用自定义历史记录，如下所示：

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，在浏览器中出现以下错误：

误差5

警告: routes路由器位置"/“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，所以我还尝试了使用Browser (HTML5 pushState) History的方式，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'));

当加载这个错误时，我会得到错误2、3和4。我认为尝试1是正确的方法，但是我不知道这个错误意味着什么并在谷歌上搜索它，给了我大量的答案(1，2，它把我和3.联系在一起，甚至4.和IndexRoute)，我尝试过，但是没有一个答案有效。

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')}
      }
    `,
  },
});

我不确定这是否是原因，但我知道，随着顶级路由器导出被删除，Rc6路由器v2.0.0-rc6发生了重大变化，但我真的不知道这对我意味着什么？我不能再用路由器了吗？如果是的话，我该怎么做呢？

经过几天的研究、尝试和错误，我放弃了，希望这里有人能帮上忙。任何指向正确方向的指示都将不胜感激。

Answer 1

最后得到了这个问题的答案，必须添加以下更改才能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'));

也许这会帮助其他人:)
