Unhandled Rejection (Error): You may not call store.getState() while the reducer is executing. The reducer has already received the state as an argument. Pass it down from the top reducer instead of reading it from the store.

是不是头皮发麻。。。哈哈

其实这不是你的代码问题，是**Redux Devtools的BUG**

为了使用redux-thunk和**Redux Devtools**是不是在生成store.js时写了如下代码

// const composeEnhancers =
    //   typeof window === 'object' &&
    //   window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ ?   
    //     window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__({
    //     }) : compose;
    
    //  const enhancer = composeEnhancers(
    //   applyMiddleware(thunk),
    // );

我们改成（这样不使用**Redux Devtools 或者试试第二种）**

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

const store = createStore(reducers, compose(
        applyMiddleware(thunk),
        window.devToolsExtension?window.devToolsExtension():f =>f
    ) )
