Redux 程序 - 以下代码的输出不会在 VS Code 终端中打印。没有错误,但未打印输出

Redux program - Output is not printed in VS Code terminal for below code. There are no errors but output is not printed

const FETCH_USERS_REQUEST = 'FETCH_USERS_REQUEST'
const FETCH_USERS_SUCCESS = 'FETCH_USERS_SUCCESS'
const FETCH_USERS_FAILURE = 'FETCH_USERS_FAILURE'

下面的代码没有显示错误,但它不起作用。我在这里没有看到任何错误,因为我是 Redux 的新手。所以我请求任何人调查这个并找出为什么输出没有打印到控制台。我可能在这里缺少一些非常基本的东西。请check.please检查图像以获取剩余代码。

//Reducer function
const reducer = (state=initialState,action)=>{
    switch(action.type)
    {
        case 'FETCH_USERS_REQUEST':
            return {
                ...state,
                loading:true

            }
            case 'FETCH_USERS_SUCCESS':
                return {
                    ...state,
                    loading:false,
                    users: action.payload,
                    error:''
    
                }
                case 'FETCH_USERS_FAILURE':
                    return {
                        ...state,
                        loading:false,
                        users: [],
                        error:action.payload
        
                    }
                
        
    }

}
//common channel
const fetchUsers = () => {
    return function(dispatch){
        dispatch(fetchUsersRequest())
        axios.get('https://jsonplaceholder.typicode.com/users')
        .then(response => {
            const users = response.data.map(user => user.id)
            dispatch(fetchUsersSuccess(users))
        })
        .catch(error => {
            dispatch(fetchUsersFailure(error.message))
        })
    }

}
const store = createStore(reducer, applyMiddleware(thunkMiddleware))
console.log("Debugging")
store.subscribe(() => {console.log((store.getState()))})
console.log("post subscribe")
store.dispatch(fetchUsers)

问题出在这一行:

store.dispatch(fetchUsers)

您必须实际调用这样的函数才能使其工作:

store.dispatch(fetchUsers())
