我遇到了这个错误:不变违规:无法在“连接(过滤器)”的上下文或道具中找到“存储”.将根组件包装在< Provider>中,或者将“store”显式传递为“Connect(Filters)”.
原文链接:https://www.f2er.com/react/300827.html应用程序的根看起来像这样:
import { AppContainer } from 'react-hot-loader'; import React from 'react'; import { render } from 'react-dom'; import { Provider } from 'react-redux'; import Root from './Root'; import configureStore from './store/configure-store'; const props = Object.assign({},JSON.parse(document.getElementById('initial-json').innerHTML)); const reduxProps = { filters: props.filters }; const store = configureStore(reduxProps); render( <Provider store={store}> <AppContainer> <Root {...props} /> </AppContainer> </Provider>,reactRoot );
根组件
export default Root extends Component { render() { return( <div className="someClass"> <Filters /> <Body /> </div> ) } }
并且过滤器正在被挂钩到Redux中,如下所示:
过滤器
class Filters extends Component {} ... const mapStateToProps = (props) => { return props; }; export default connect(mapStateToProps)(Filters); // have also tried: connect()(Filters);
起初,我认为这可能只是组件如何连接到Redux存储的错误,但是我已经尝试了嵌套在Root内部的几个不同的组件,包括Root本身.我还尝试仅在提供程序中包装过滤器,但这会引入RHL重新加载存储的问题.
最后,我开始怀疑这与商店的配置方式有关.所以我正在通过configure-store查看:
配置-store.js
import { createStore,applyMiddleware,compose } from 'redux'; import createSagaMiddleware from 'redux-saga'; import logger from 'redux-logger'; import rootReducer from '../reducers'; import rootSaga from '../sagas'; const sagaMiddleware = createSagaMiddleware(); const enhancer = compose(applyMiddleware(sagaMiddleware,logger)); export default function configureStore(initialState) { const store = createStore(rootReducer,initialState,enhancer); sagaMiddleware.run(rootSaga); if (module.hot) { /* eslint-disable */ module.hot.accept('../reducers',() => store.replaceReducer(require('../reducers').default) ); } return store; }
到目前为止我的问题:我正在配置商店的方式有什么不妥之处,还是有其他我在这里看不到的东西?谢谢.
编辑:
应该可以通过this.context.store从根组件访问redux存储.从根组件记录时,this.context返回一个空对象…
