Question

我正在研究React / Redux电子商务项目，我正在制作添加用户地址的功能，功能正常，我能够添加新的用户地址，但问题是我必须刷新页面到显示新的地址卡，地址卡保存后没有显示地址，我要刷新页面显示新地址，任何人都可以帮忙解决这个问题，我的动作，reducer和saga文件附在下面

操作文件

const addAddressByBuyerId = (address: Object, params: string) => ({
    type: Types.ADD_ADDRESS_BY_BUYER_ID,
    address,
    params,
});
const addAddressByBuyerIdSuccess = (addresses: Object, params: string) => ({
    type: Types.ADD_ADDRESS_BY_BUYER_ID_SUCCESS,
    addresses,
    params,
});
const addAddressByBuyerIdFailure = (errorMessage: Object) => ({
    type: Types.ADD_ADDRESS_BY_BUYER_ID_FAILURE,
    errorMessage,
});

传奇文件

function* addAddressByBuyerId(action) {
        try {
            const response = yield call(api.account.postAddressByBuyerId, action.address);
            if (response.ok && response.data && {}.hasOwnProperty.call(response.data, 'data')) {
                yield put(Actions.getAddressesByBuyerId());
                yield put(Actions.addAddressByBuyerIdSuccess(response.data.data));
            } else {
                yield put(Actions.addAddressByBuyerIdFailure(response.errorMessage));
            }
        } catch (error) {
            yield put(Actions.addAddressByBuyerIdFailure());
        }
    }
    function* watchAddAddressByBuyerId(): Generator<void, void, void> {
        yield takeLatest(Types.ADD_ADDRESS_BY_BUYER_ID, addAddressByBuyerId);
    }

减少文件

export const addAddressByBuyerId = (state: Object = INITIAL_STATE) => ({
    ...state,
    isLoading: true,
    successMessage: null,
    errorMessage: null,
});

export const addAddressByBuyerIdSuccess = (state: Object = INITIAL_STATE, action: Object) => {
    const successMessage = I18n.getText('account.address-added', {}, 'Address added!');
    return {
        ...state,
        address: action.address,
        isLoading: false,
        successMessage,
    };
};

export const addAddressByBuyerIdFailure = (state: Object = INITIAL_STATE, action: Object) => ({
    ...state,
    errorMessage: action.errorMessage || genericError,
    isLoading: false,
});

你有一个错字。

在操作文件中，您返回包含addresses属性的对象（请参阅addAddressByBuyerIdSuccess函数）。

但是在您的reducer（addAddressByBuyerIdSuccess）中，您正在访问未定义的address属性。

我无法在redux saga中显示新的用户地址
