我已经使用了thunk中间件，但仍然得到错误，这是为什么？-------我错过了什么？x1c 0d1x
App.js

useEffect(() => {
    dispatch(getPosts())
  }, [dispatch])

操作文件：

import * as api from "../api/index"

export const getPosts = async dispatch => {
    try {
        const { data } = await api.fetchPosts()
        dispatch({ type: "GET_ALL", payload: data })
    } catch (error) {
        console.log(error)
    }

异径管文件：

export const reducers = (posts = [], action) => {
    switch (action.type) {
        case "GET_ALL":
            return action.payload

        default:
            return posts
    }
}

存储文件：

import thunk from "redux-thunk";
import { reducers } from "../reducers/index"
import { createStore, applyMiddleware, compose } from 'redux';

const store = createStore(reducers, compose(applyMiddleware(thunk)))
export default store
