你可以通过将此代码添加到动作文件中来清空减速器的数据，

首先导入所有类型:

import * as types from './types';

将此代码添加到注销操作

for(let key of Object.values(types)) {
        dispatch({ type: key, payload: [] });
    }

    }

这种方法非常正确:销毁任何特定状态“NAME”以忽略并保留其他状态。

const rootReducer = (state, action) => {
    if (action.type === 'USER_LOGOUT') {
        state.NAME = undefined
    }
    return appReducer(state, action)
}

为了避免Redux引用初始状态的相同变量，我的建议是:

// write the default state as a function
const defaultOptionsState = () => ({
  option1: '',
  option2: 42,
});

const initialState = {
  options: defaultOptionsState() // invoke it in your initial state
};

export default (state = initialState, action) => {

  switch (action.type) {

    case RESET_OPTIONS:
    return {
      ...state,
      options: defaultOptionsState() // invoke the default function to reset this part of the state
    };

    default:
    return state;
  }
};

我在使用typescript时的解决方案，建立在Dan Abramov的答案之上(redux类型使得不可能将undefined作为第一个参数传递给reducer，所以我将初始根状态缓存在一个常量中):

// store

export const store: Store<IStoreState> = createStore(
  rootReducer,
  storeEnhacer,
)

export const initialRootState = {
  ...store.getState(),
}

// root reducer

const appReducer = combineReducers<IStoreState>(reducers)

export const rootReducer = (state: IStoreState, action: IAction<any>) => {
  if (action.type === "USER_LOGOUT") {
    return appReducer(initialRootState, action)
  }

  return appReducer(state, action)
}


// auth service

class Auth {
  ...

  logout() {
    store.dispatch({type: "USER_LOGOUT"})
  }
}

在服务器中，有一个变量:global。isSsr = true 在每个reducer中，我都有一个const: initialState 要重置存储中的数据，我对每个Reducer执行以下操作:

appReducer.js的例子:

 const initialState = {
    auth: {},
    theme: {},
    sidebar: {},
    lsFanpage: {},
    lsChatApp: {},
    appSelected: {},
};

export default function (state = initialState, action) {
    if (typeof isSsr!=="undefined" && isSsr) { //<== using global.isSsr = true
        state = {...initialState};//<= important "will reset the data every time there is a request from the client to the server"
    }
    switch (action.type) {
        //...other code case here
        default: {
            return state;
        }
    }
}

最后在服务器的路由器上:

router.get('*', (req, res) => {
        store.dispatch({type:'reset-all-blabla'});//<= unlike any action.type // i use Math.random()
        // code ....render ssr here
});
