使用React入门套件同构时,使用Apollo客户端使用Apollo客户端时获取校验和无效的警告



我正在尝试使用Apollo客户端,我遇到了一些问题,将其放入带有Redux的React入门套件中。https://github.com/kriasoft/react-starter-kit/tree/feature/redux

尝试从这里使用这些技术:http://dev.apollodata.com/react/server-side-rendering.html

,但我得到了错误

warning.js:36Warning: React attempted to reuse markup in a container but the checksum was invalid. This generally means that you are using server rendering and the markup generated on the server was not what the client was expecting. React injected new markup to compensate which works but you have lost many of the benefits of server rendering. Instead, figure out why the markup being generated is different on the client or server:
 (client) </div></header><div data-reactid="19">Lo
 (server) </div></header><div class="Home-root-2IM

这是我的实施

// server.js
...
const component = (
  <App context={context}>
    <ApolloProvider client={context.client} store={context.store}>
      {route.component}
    </ApolloProvider>
  </App>
);

await getDataFromTree(component);
data.children = ReactDOM.renderToString(component);
data.style = [...css].join('');
data.scripts = [
  assets.vendor.js,
  assets.client.js,
];
data.state = context.store.getState();
if (assets[route.chunk]) {
  data.scripts.push(assets[route.chunk].js);
}
const html = ReactDOM.renderToStaticMarkup(<Html {...data} />);
res.status(route.status || 200);
res.send(`<!doctype html>${html}`);
...

和客户端

// client.js
...
const component = (
  <App context={context}>
    <ApolloProvider client={context.client} store={context.store}>
      {route.component}
    </ApolloProvider>
  </App>
);
appInstance = ReactDOM.render(
 component,
  container,
  () => onRenderComplete(route, location),
);
...

// Home.js
class Home extends React.Component {
  static propTypes = {
    collections: PropTypes.arrayOf(PropTypes.shape({
      id: PropTypes.string.isRequired,
      title: PropTypes.string.isRequired,
      subtitle: PropTypes.string.isRequired,
      photo: PropTypes.string,
    })).isRequired,
  };
  render() {
    const props = this.props;
    const { loading, allCollections } = props.data;
    if (loading) {
      return <div>Loading</div>;
    } else {
      return (
        <div className={s.root}>
          <div className={s.container}>
            <h1 className={s.title}>Collections</h1>
            <ul>
              {allCollections.map((collection) =>
                <li key={collection.id}>
                  <h3>{collection.title}</h3>
                  <img src={collection.photo} width="200"/>
                </li>
              )}
            </ul>
          </div>
        </div>
      );
    }
  }
}
Home.propTypes = {
  data: PropTypes.shape({
    loading: PropTypes.bool.isRequired,
    allCollections: PropTypes.array,
  }).isRequired,
};

const HomeWithStyles =  withStyles(s)(Home);
const HomeWithData = graphql(getQuery)(HomeWithStyles);
export default connect()(HomeWithData);

// App.js
import React, { Children, PropTypes } from 'react';
const ContextType = {
  // Enables critical path CSS rendering
  // https://github.com/kriasoft/isomorphic-style-loader
  insertCss: PropTypes.func.isRequired,
  // Integrate Redux
  // http://redux.js.org/docs/basics/UsageWithReact.html
  store: PropTypes.shape({
    subscribe: PropTypes.func.isRequired,
    dispatch: PropTypes.func.isRequired,
    getState: PropTypes.func.isRequired,
  }).isRequired,
  client: PropTypes.object.isRequired,
};
/**
 * The top-level React component setting context (global) variables
 * that can be accessed from all the child components.
 *
 * https://facebook.github.io/react/docs/context.html
 *
 * Usage example:
 *
 *   const context = {
 *     history: createBrowserHistory(),
 *     store: createStore(),
 *   };
 *
 *   ReactDOM.render(
 *     <App context={context}>
 *       <Layout>
 *         <LandingPage />
 *       </Layout>
 *     </App>,
 *     container,
 *   );
 */
class App extends React.PureComponent {
  static propTypes = {
    context: PropTypes.shape(ContextType).isRequired,
    children: PropTypes.element.isRequired,
  };
  static childContextTypes = ContextType;
  getChildContext() {
    return this.props.context;
  }
  render() {
    // NOTE: If you need to add or modify header, footer etc. of the app,
    // please do that inside the Layout component.
    return Children.only(this.props.children);
  }
}
export default App;

,因此答案是未为阿波罗客户端数据设置初始状态

// client.js 
let apolloOptions = {
  ssrMode: false,
  initialState: { apollo: { data: window.APP_STATE.apollo.data } }, // NOT __APOLLO_STATE__ as set in some of the examples online 
  ssrForceFetchDelay: 500,
  networkInterface: createNetworkInterface({
    uri: window.APP_STATE.runtime.graphUri,
  }),
  opts: {
    credentials: 'same-origin',
  },
};
const client = new ApolloClient(apolloOptions);

和在服务器上

// server.js
...
// data.state gets rendered by the server to client as APP_STATE
data.state = context.store.getState();
data.state.apollo = client.store ? client.store.getState().apollo : null;
...
