redux从后端获得数据怎么传递给state

Question

比如一个博客，首次进入页面，我从后端同时获得了user，article，comment，我是一个一个传递给他们吗？就像这样const article = (article) => ({type: 'INIT_ARTICLE', article});const user = (user) => ({type: 'INIT_USER', user});const comment = (user) => ({type: 'INIT_COMMENT', comment});获取后触发三个dispatch吗？目前我的做法const blogReducer = (state = {}, action) => {    switch (action.type) {        case RECEIVE_DATA:            return action.data;        default:            return {                comment: commentHelper(state.comment, action),                article: articleHelper(state.article, action),                user: userHelper(state.user, action),            }    }}    const commentHelper = (state = [], action) => {        switch (action.type) {            case 'ADD_COMMENT':                return [...state, action.comment];            default:                return state;         }        }获取数据时触发RECEIVE_DATA，更改comment时，触发ADD_COMMENT就行。不知是否合理。

更好的方式是合并成一个dispatch:

const data = (user, article, comment) => ({type: 'INIT_BLOG', data: {user, article, comment}})

dispatch 这个Action

reducer:

const blogReducer = (state = {}, action) => {

    switch (action.type) {

        case 'INIT_BLOG':

            return {...state,

                comment: action.data.comment,

                article: action.data.article,

                user: action.data.user

   

            };

        case 'ADD_COMMENT':

            return {...state, comment: [...state, action.data.comment]};

              

        default:

            state;

    }

}

你上面的写法功能是可以的，但不符合reducer的习惯写法
