Javascript React Router Redux返回导致无限循环

我有一个用React+Redux构建的应用程序。我使用React路由器和React路由器Redux进行路由。我注意到了非常奇怪的行为。单击“上一步”按钮一次后，从0到-1将正常工作。但是，当您第二次单击它，打算从-1转到-2时，您将返回到0。随后的单击在0和-1之间循环。此行为与一致，而不是从历史中弹出并推到最后一个位置。这是这些库的预期行为吗？如果不是，我是不是用错了

以下是我认为相关的代码片段。文件不完整（太大），但我认为这是必要的，如果需要，愿意分享更多

root.tsx

：

import { Router, browserHistory } from 'react-router'
import { syncHistoryWithStore } from 'react-router-redux'

const history = syncHistoryWithStore(browserHistory, store)

const renderAsyncConnect = props =>
  <ReduxAsyncConnect
    {...props}
    helpers={{ client }}
    filter={notDeferredItems}
  />

const Root = () =>
  <Provider store={store} key="provider">
    <Router render={renderAsyncConnect} history={history}>
      {routes}
    </Router>
  </Provider>

export default Root

create store.js

：

import thunk from 'redux-thunk'
import { composeWithDevTools } from 'redux-devtools-extension/logOnly'
import { createStore as _createStore, applyMiddleware } from 'redux'
import { routerMiddleware } from 'react-router-redux'

import clientMiddleware from './middleware/client-middleware'
import browseStateMiddleware from './middleware/browse-state-middleware'

import combinedReducers from './modules/reducer'
import types from './modules/account/types'

export default function createStore(history, client, data, persister) {
  const storeData = data

  // Sync dispatched route actions to the history
  const reduxRouterMiddleware = routerMiddleware(history)

  const middleware = [
    browseStateMiddleware,
    reduxRouterMiddleware,
    clientMiddleware(client),
    analyticsMiddleware,
    thunk,
  ]

  const composeEnhancers = composeWithDevTools(
    {
      // options like actionSanitizer, stateSanitizer
    }
  )

  // See https://stackoverflow.com/questions/35622588/how-to-reset-the-state-of-a-redux-store/35641992#35641992
  const rootReducer = (state, action) => {
    if (action.type === types.LOGOUT) {
      if (persister) {
        persister.clear()
      }
      return combinedReducers(undefined, action)
    }

    return combinedReducers(state, action)
  }

  const store = _createStore(
    rootReducer,
    storeData,
    composeEnhancers(
      applyMiddleware(...middleware)
      // other store enhancers
    )
  )

  window.store = store

  if (__DEVELOPMENT__ && module.hot) {
    module.hot.accept('./modules/reducer', () => {
      store.replaceReducer(System.import('./modules/reducer'))
    })
  }

  return store
}

有什么问题吗？

此问题很可能是由以下原因引起的：

const browseStateMiddleware = ({ dispatch, getState }) => next => action => {
  if (action.type === '@@router/LOCATION_CHANGE') {
    // some dispatching of actions deleted here for clarity
    return next(action)
  }
}

您分派的操作发生在路由在存储中更新之前，这导致此行为源自（我看到它在版本4.0.8中被复制）

处理此问题的一种方法是执行以下操作：

const browseStateMiddleware = ({ dispatch, getState }) => next => action => {
  if (action.type === '@@router/LOCATION_CHANGE') {
    next(action);
    // dispatch your actions here
    return;
  }
}

这样，您就可以保证在正确的时间正确更新存储。

我也有类似的问题。在哪里可以解决这个问题？

const browseStateMiddleware = ({ dispatch, getState }) => next => action => {
  if (action.type === '@@router/LOCATION_CHANGE') {
    next(action);
    // dispatch your actions here
    return;
  }
}
