redux- API -中间件从两个不同的API调用中分配状态

// actions.js
import axios from 'axios';

export const fetchData = () => {
  return (dispatch) => {
    dispatch({ type: 'FETCH_DATA_REQUEST' });

    axios.get('https://api.example.com/data1')
      .then(response => {
        dispatch({ type: 'FETCH_DATA_SUCCESS', payload: response.data });
      })
      .catch(error => {
        dispatch({ type: 'FETCH_DATA_FAILURE', payload: error.message });
      });
  };
};

// reducer.js
const initialState = {
  data: null,
  loading: false,
  error: null
};

const reducer = (state = initialState, action) => {
  switch (action.type) {
    case 'FETCH_DATA_REQUEST':
      return { ...state, loading: true };
    case 'FETCH_DATA_SUCCESS':
      return { ...state, loading: false, data: action.payload };
    case 'FETCH_DATA_FAILURE':
      return { ...state, loading: false, error: action.payload };
    default:
      return state;
  }
};

// store.js
import { createStore, applyMiddleware } from 'redux';
import thunk from 'redux-thunk';
import reducer from './reducer';

const store = createStore(reducer, applyMiddleware(thunk));

export default store;

// MyComponent.js
import React, { useEffect } from 'react';
import { useDispatch, useSelector } from 'react-redux';
import { fetchData } from './actions';

const MyComponent = () => {
  const dispatch = useDispatch();
  const data = useSelector(state => state.data);
  const loading = useSelector(state => state.loading);
  const error = useSelector(state => state.error);

  useEffect(() => {
    dispatch(fetchData());
  }, [dispatch]);

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

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

  return (
    <div>
      {data && data.map(item => (
        <div key={item.id}>{item.name}</div>
      ))}
    </div>
  );
};

export default MyComponent;
