如何使用redux从我自己的api获取数据？

npm install redux react-redux @reduxjs/toolkit axios

// store.js
import { configureStore } from '@reduxjs/toolkit';
import thunk from 'redux-thunk';
import rootReducer from './rootReducer';

const store = configureStore({
  reducer: rootReducer,
  middleware: [thunk],
});

export default store;

// dataSlice.js
import { createSlice, createAsyncThunk } from '@reduxjs/toolkit';
import axios from 'axios';

export const fetchData = createAsyncThunk('data/fetchData', async () => {
  const response = await axios.get('/api/data');
  return response.data;
});

const dataSlice = createSlice({
  name: 'data',
  initialState: { entities: [], loading: 'idle' },
  reducers: {},
  extraReducers: (builder) => {
    builder
      .addCase(fetchData.pending, (state) => {
        state.loading = 'pending';
      })
      .addCase(fetchData.fulfilled, (state, action) => {
        state.loading = 'fulfilled';
        state.entities = action.payload;
      })
      .addCase(fetchData.rejected, (state) => {
        state.loading = 'rejected';
      });
  },
});

export default dataSlice.reducer;

// rootReducer.js
import { combineReducers } from 'redux';
import dataReducer from './dataSlice';

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

export default rootReducer;

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

function App() {
  const dispatch = useDispatch();
  const { entities, loading } = useSelector((state) => state.data);

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

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

  if (loading === 'rejected') {
    return <div>Error fetching data</div>;
  }

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

export default App;
