我无法在 useState 钩子中使用来自 redux 商店的数据来展示图像

如何解决我无法在 useState 钩子中使用来自 redux 商店的数据来展示图像

enter image description here 此处的 singleCard 对象包含有关产品的所有详细信息，例如 id、title、src 等。我可以将 singleCard 控制台记录为 console.log(singleCard)，其中显示从 redux store 传递的所有数据，但我无法访问其单个元素，如 singleCard.src 或 singleCard.title 。我想在 useState 钩子的帮助下通过将 initialState 设置为 singleCard.src 来展示图像，我该怎么做？？

    

        function Singlecard() {
        
        
          const dispatch = useDispatch();
          const { id } = useParams();
          const productId = id;
          const productDetails = useSelector((state) => state.productDetails);
          const { loading,error,singleCard } = productDetails;
        
          const [currentImg,setcurrentimg] = useState(singleCard.src);
        
          console.log(currentImg);
        
          useEffect(() => {
            dispatch(detailsProduct(productId));
          },[dispatch,productId]);
    
         return (
            <div>
               <div className="singlecard-wrapper">
                  <div className="singlecard">
                    {/* card left */}
                    <div className="product-img">
                      <div className="img-display">
                        <div className="img-showcase">
                          <img src={currentImg} height="552px" width="552px" />
                        </div>
                      </div>
                      <div className="img-select">
                        <div className="img-item">
                          <Link to="#">
                            <img
                              src="https://instagram.fccu3-1.fna.fbcdn.net/v/t51.2885-15/e35/121105212_197680348436281_873870113726337107_n.jpg?tp=1&_nc_ht=instagram.fccu3-1.fna.fbcdn.net&_nc_cat=101&_nc_ohc=nsNxf_rVgeUAX9KUkp-&edm=AP_V10EAAAAA&ccb=7-4&oh=6b955579988a6dcbef129b3ad606fecd&oe=60918B32&_nc_sid=4f375e"
                              onClick={(e) => setcurrentimg(e.target.src)}
                            />
                          </Link>
                        </div>
                   </div>
              </div>
        </div>
     </div>

在 useState 中使用 singleCard.src 时，它显示无法读取 undefined 的属性“src”。请帮忙！

productAction：

    export const detailsProduct = (productId) => async (dispatch) => {
  dispatch({ type: PRODUCT_DETAILS_REQUEST,payload: productId });
  try {
    const response = await axios.get(`/cardUpload/${productId}`);
    dispatch({ type: PRODUCT_DETAILS_SUCCESS,payload: response.data });
  } catch (err) {
    dispatch({
      type: PRODUCT_DETAILS_FAIL,payload:
        err.response && err.response.data.message
          ? err.response.data.message
          : err.message,});
  }
};

productReducer：

    export const detailsProduct = (productId) => async (dispatch) => {
  dispatch({ type: PRODUCT_DETAILS_REQUEST,});
  }
};

商店：

import { applyMiddleware,combineReducers,compose,createStore } from "redux";
import thunk from "redux-thunk";
import {
  productDetailsReducer,productListReducer,} from "./reducers/productReducers";
const initialState = {};

const reducer = combineReducers({
  productList: productListReducer,productDetails: productDetailsReducer,});

const composeEnhancer = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
const store = createStore(
  reducer,initialState,composeEnhancer(applyMiddleware(thunk))
);

export default store;
