Reducer没有捕获LOCATION_CHANGE动作

Question

我正在努力让我的React/Redux应用程序根据操作更新URL.我做了很多环顾四周.我以为我有一个处理它,但显然我错过了一些东西.我还有其他正确响应的减速器.

目前,我只是想记录行动.

路由减速器

const initialState = { locationBeforeTransitions: null };

export default function routing(state = initialState, action)
{
  switch (action.type)
  {
    case 'LOCATION_CHANGE':
      console.log(action)

    default:
      return state

  }

}

import { syncHistoryWithStore }                  from 'react-router-redux';
import { browserHistory }                        from 'react-router'
import   thunkMiddleware                         from 'redux-thunk'

import { fetchSuitesAndFails, fetchResults } from './actions/actions';
import   rootReducer                         from './reducers/index'

const enhancers = compose(
  window.devToolsExtension ? window.devToolsExtension() : f => f
);

const loggerMiddleware = createLogger()

/*

*/

export const store = createStore(
  rootReducer,
  enhancers,
  applyMiddleware(
    thunkMiddleware, // lets us dispatch() functions
    loggerMiddleware // neat middleware that logs actions
  )
);

// Export the history so we can keep track of things
export const history = syncHistoryWithStore(browserHistory, store);

if (module.hot) {
  // Enable Webpack hot module replacement for reducers
  module.hot.accept('./reducers/index', () => {
    const nextRootReducer = require('./reducers/index').default
    store.replaceReducer(nextRootReducer)
  })
}

const rootReducer = combineReducers({

  routing: routerReducer

export default rootReducer

您可以使用字符串"@@ router/LOCATION_CHANGE"来捕获操作.

react-router-redux为此提供了const

import { LOCATION_CHANGE } from 'react-router-redux'

....
case LOCATION_CHANGE:
      console.warn('LOCATION_CHANGE from your reducer',action)
      return state
