如何在vuex模块中编写异步函数

async fetchData({ commit }) {
  try {
    const response = await axios.get('/api/data');
    commit('SET_DATA', response.data);
  } catch (error) {
    console.error(error);
  }
}

this.$store.dispatch('fetchData');

// store.js

import Vue from 'vue';
import Vuex from 'vuex';
import axios from 'axios';

Vue.use(Vuex);

const store = new Vuex.Store({
  modules: {
    myModule: {
      state: {
        data: null
      },
      mutations: {
        SET_DATA(state, data) {
          state.data = data;
        }
      },
      actions: {
        async fetchData({ commit }) {
          try {
            const response = await axios.get('/api/data');
            commit('SET_DATA', response.data);
          } catch (error) {
            console.error(error);
          }
        }
      }
    }
  }
});

export default store;

this.$store.dispatch('myModule/fetchData');
