最近在用学习vuex，组件mapState,mapGetters拿数据出现了问题求教

首先我封装了axios get请求 文件为http.js

请输入import axios from 'axios'
import qs from 'qs'
axios.defaults.timeout = 10000;
export function get(url, params) {
    return new Promise((resolve, reject) => {
        axios.get(url, {
            params: params
        }).then(res => {
            resolve(res.data);
        }).catch(err => {
            reject(err.data)
        })
    });
}

然后在api.js 中暴露出来首页的数据请求

import {get,post} from './http'
// const url = '/api/'
// 首页总数据
export const indexRequest = p =>get('/api/getIndex',p)

在vuex中建立了一个首页模块 home.js

import {
    indexRequest
} from "@/request/api"
import {
    RECEIVE_INDEXDATAS
} from '../types'
const state = {
    gtId: 0,
    indexRequestData: []
}

const getters = {
    indexRequestData:state=>state.indexRequestData
}

const mutations = {
    [RECEIVE_INDEXDATAS](state, {
        indexRequestData
    }) { 
        state.indexRequestData = indexRequestData
    },
    gtIdChange: function (state, gtId) {
        state.gtId = gtId
    }
}

const actions = {
    async requestIndex({
        commit,
        state
    }) {
        const {
            gtId
        } = state
        const indexRequestData = await indexRequest({
            firstFl: gtId
        })
        commit(RECEIVE_INDEXDATAS, {
            indexRequestData
        })
    }
}
export default {
    state,
    getters,
    mutations,
    actions
}

在vuex index.js中调用了home.js

import Vue from 'vue'
import Vuex from 'vuex'
import home from './modules/home'

Vue.use(Vuex)

export default new Vuex.Store({

  modules: {
    home
  }
});

最后在我的组件 home.vue中

import { mapState,mapGetters } from "vuex";
import { indexRequest } from "@/request/api";
export default {
  name: "home",
  data() {
    return {
    };
  },
  mounted() {
    this.$store.dispatch("requestIndex");
    console.log(this.indexRequestData)
  },
  methods: {
  },
  computed: {
    ...mapGetters(["indexRequestData"])
  }
};

在home.vue中 用mapState拿state中数据渲染不到页面上
用mapGetters拿数据可以渲染到页面上但是console.log(this.indexRequestData)为空值。
我现在想对拿到的数据indexRequestData做处理在分发给各个组件 请问怎么解决？
