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,但我很难按照变更日志来解决所有重大变更。我想我解决了所有的变化,但我仍然无法让它发挥作用。

警告:[react-router] 位置“/”不匹配任何路由

这是我为解决这些变化所做的分步指南。首先我更新了 npm 模块。

我以前的 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 react-router 的直接依赖项。安装最新模块后,我重新加载了页面并收到以下错误:

错误 1:

警告:[react-router] 看来您已向 <Router/> 提供了一个已弃用的历史记录对象,请使用 React Router 提供的历史记录与 import browserHistory from 'react-router'import hashHistory from 'react-router'。如果您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:上下文类型失败:提供给Relay(App) 的属性/上下文relay 无效,应将undefined 视为符合RelayEnvironment 接口的对象。

in Relay(App) (created by RouterContext)
in RouterContext (created by Router)
in Router

错误 3:

警告:上下文类型失败:Relay(App) 中未指定必需的上下文 route

in Relay(App) (created by RouterContext)
in RouterContext (created by Router)
in Router

错误 4:

未捕获的不变违规:RelayContainer:Relay(App) 使用无效的中继上下文 undefined 呈现。确保 React 上下文中的 relay 属性符合 RelayEnvironment 接口。

第一个错误提供了一个方便的链接到 react-router 的升级指南,所以我按照它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'));

这会在浏览器中出现以下错误:

错误 5

警告:[react-router] 位置“/”不匹配任何路由

我相信这是我想要的解决方案。但是我不确定,所以我也尝试了 Browser (HTML5 pushState) History 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,我返回错误 2、3 和 4。我认为尝试 1 是正确的方法,但我不知道此错误是什么意思,用谷歌搜索它,给了我很多答案 (1, @ 987654323@,它把我链接到3,甚至用IndexRoute链接到4),我试过了,但没有一个答案奏效。

我的 App.js 文件长这样,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 react-router v2.0.0-rc6 发生了重大变化,移除了***路由器导出,但我真的不知道这对我意味着什么?难道我不能再使用路由器了吗?如果是这样,我应该怎么做?

经过几天的研究和反复试验,我放弃了,希望这里有人可以提供帮助。任何指向正确方向的指针将不胜感激。

【参考方案1】:

终于得到了这个问题的答案,不得不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'));

也许这对其他人有帮助:)
