Curried 函数导致错误，但如果没有 Curried 则有效

Question

export const postMoviePopular = url = dispatch => {    const data = axios.get(url);    dispatch(saveMoviePopular(data));}const saveMoviePopular = payload => {    return {        type: POST_MOVIE_POPULAR,        payload    }}这是我的代码不起作用，因为它是柯里化的，但如果它不是像下面一样柯里化，它可以工作，这是为什么？export const postMoviePopular = url => {    return dispatch => {        const data = axios.get(url);        dispatch(saveMoviePopular(data));    }    } 我想知道它是否与我调用 mapDispatchToProps 的方式有关？？？componentDidMount() {        this.props.postMDBConfig(`https://api.themoviedb.org/3/configuration?api_key=${this.props.apiKey}`);        this.props.postMoviePopular(`https://api.themoviedb.org/3/movie/popular?api_key=${this.props.apiKey}&language=en-US&page=1&region=US`)    }const mapDispatchToProps = (dispatch) => {    return {        postMDBConfig: url => dispatch(postMDBConfig(url)),        postMoviePopular: url => dispatch(postMoviePopular(url))    }}

Answer 1

你需要一个return语句。还有一个箭头。

export const postMoviePopular = url => dispatch => {

    const data = axios.get(url);

    return dispatch(saveMoviePopular(data));

}
