在redux-thunk中调用另一个异步函数

Question

我正在构建一个react应用程序并使用redux-thunk进行异步操作.我有两个功能getActivities(),createActivity()并且我想在成功调用后者之后调用前者.但是如果我放入它的getActivities()内部then块createActivity()就不会被调用(这是通过没有看到我放入的console.log()来证明的getActivities()).这两个功能:

export const getActivities = () => dispatch => {
console.log('again');
return axios.get(ENV.stravaAPI.athleteActivitiesBaseEndPoint, autHeaders)
    .then(resp => {
        dispatch({type: actions.GET_ACTIVITIES, activities: resp.data})
    })
    .catch(err => {
        if(window.DEBUG)console.log(err);
    })
};

export const createActivity = data => dispatch => {

dispatch(setLoadingElement('activityForm'));
return axios.post(URL, null, autHeaders)
    .then(resp => {
        if (resp.status === 201) {
            dispatch(emptyModal());
        }
        // I WANT TO CALL getActivities() HERE
        dispatch(unsetLoadingElement('activityForm'));
    })
    .catch(err => {
        if(window.DEBUG) console.log(err.response.data.errors);
        dispatch(unsetLoadingElement('activityForm'));
    });
};

我如何在另一个内部打电话？

为了从一个动作创建者内部调用另一个动作,你只需要dispatch像这样的动作dispatch(getActivities())

export const createActivity = data => dispatch => {

    dispatch(setLoadingElement('activityForm'));
    return axios.post(URL, null, autHeaders)
        .then(resp => {
            if (resp.status === 201) {
                dispatch(emptyModal());
            }
            dispatch(getActivities());
            dispatch(unsetLoadingElement('activityForm'));
        })
        .catch(err => {
            if(window.DEBUG) console.log(err.response.data.errors);
            dispatch(unsetLoadingElement('activityForm'));
        });
 };
