如何获取axios.get数据以及将其置于redux reducer初始状态的何处

npm install axios redux react-redux

import axios from 'axios';

export const fetchData = () => {
  return (dispatch) => {
    axios.get('your_api_endpoint')
      .then(response => {
        dispatch({ type: 'FETCH_DATA_SUCCESS', payload: response.data });
      })
      .catch(error => {
        dispatch({ type: 'FETCH_DATA_FAILURE', payload: error.message });
      });
  };
};

const initialState = {
  data: null,
  error: null,
};

const dataReducer = (state = initialState, action) => {
  switch (action.type) {
    case 'FETCH_DATA_SUCCESS':
      return {
        ...state,
        data: action.payload,
        error: null,
      };
    case 'FETCH_DATA_FAILURE':
      return {
        ...state,
        data: null,
        error: action.payload,
      };
    default:
      return state;
  }
};

export default dataReducer;

import { combineReducers } from 'redux';
import dataReducer from './dataReducer';

const rootReducer = combineReducers({
  data: dataReducer,
});

export default rootReducer;

import React, { useEffect } from 'react';
import { connect } from 'react-redux';
import { fetchData } from '../actions/dataActions';

const YourComponent = ({ data, error, fetchData }) => {
  useEffect(() => {
    fetchData();
  }, []);

  if (error) {
    return <div>Error: {error}</div>;
  }

  if (!data) {
    return <div>Loading...</div>;
  }

  return (
    <div>
      {/* Render your component with the fetched data */}
    </div>
  );
};

const mapStateToProps = (state) => {
  return {
    data: state.data.data,
    error: state.data.error,
  };
};

export default connect(mapStateToProps, { fetchData })(YourComponent);
