我正在学习 Redux，我对这里发生的事情感到非常困惑。我正在使用 thunk 并且 GET_ITEMS 在我的减速器中，所以我不确定我做错了什么？错误在dispatch(getItemsAction());

Redux.js

function reducer(state, action) {
    switch (action.type) {
        case 'GET_ITEMS':
            return {
                ...state,
                items: action.payload,
                loading: false,
            };
        case 'ADD_ITEM':
            return {
                ...state,
                items: [...state.items, action.payload],
            };
        case 'DELETE_ITEM':
            return {
                ...state,
                items: state.items.filter(item => item.id !== action.payload),
            };
        case 'ITEMS_LOADING':
            return {
                ...this.state,
                loading: true,
            };
        default:
            return state;
    }
}

export const getItemsAction = () => ({
    return(dispatch) {
        axios.get('api/items').then(response => {
            console.log(response);
            dispatch({ type: 'GET_ITEMS', payload: response.data });
        });
    }, …
