javascript - redux react 错误 : Actions must be plain objects

Question

我正在学习 redux 并在设置完所有设置后收到此消息:

    Error: Actions must be plain objects. Use custom middleware for async actions.

我阅读了 10 个关于这个错误的不同问题，但没有一个解决方案适合我。这是我在 github 上的项目，以防问题不在以下代码中:https://github.com/CodeNinja1395/Test-task-for-inCode/tree/redux

商店:

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

const initialState = {};

const middleware = [thunk];


const store = createStore(
  rootReducer,
  initialState,
  applyMiddleware(thunk)
);

export default store;

Action :

import {FETCH_DATA} from './types';

export const fetchData = () => dispatch => {
  fetch('https://raw.githubusercontent.com/CodeNinja1395/Test-task-for-inCode/master/clients.json')
    .then(posts =>
      dispatch({
        type: FETCH_DATA,
        payload: posts
      })
    );
};

您使用旧版本的 redux - v1，而新版本是 v4。当您升级到 v4 时，它会起作用。

npm install redux@^4.0.0
