ts:如何访问redux存储内部的状态

Question

我的还原器集合存储在rootReducer中(有普通还原器和切片还原器(。

我需要使用useSelector钩子访问这些减速器内部的状态。

我的商店：

const store = configureStore({reducer : rootReducer});

RootReducer:

const reducers = {
getName,
getSomething,
getCollection,
getSomethingelse
}
const rootReducer = combineReducers(reducers);

样本缩减器(createSlice(：

const initialState:any = {
nameList:[]
}
const setNameList = createSlice({
name:"setNameList",
initialState,
reducers:{
setNameList(state,action){
state.nameList.push(action.payload);
}
}
});

另一个样品还原剂(正常(：

export default function somethingReducer(state = {
something:{}
}, action) {
switch(action.type){
case C.SOMETHING_ZONE:{        
return {
...state
,something :action.payload
}
}
default : {}
}
return state
}

我试过了，

const name = useSelector(state => state.getName.nameList)
const something = useSelector(state => state.getSomething.something)

但出现错误：Property 'getName' does not exist on type 'DefaultRootState'.

RootReducer中存在问题。更改常量变量的方式如下：

const reducers = {
getName: setNameList.reducer,
getSomething: somethingReducer.reducer  
}

不要忘记导入减速器，并以相同的方式使用其他减速器。
