问在react-thunk中遇到的问题,请问这个是什么原因导致的？

import {createStore,compose,applyMiddleware } from 'redux'

import thunk from 'redux-thunk'

import reducer from '../Reducer/index'

const composeEnhancers =

window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ ?

window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__({}) : compose;

const enhancer = composeEnhancers(

applyMiddleware(thunk)

);

const store = createStore(reducer, enhancer);

export default store;

这是store的配置 中间件使用了thunk

function mapdispatchtoprops(dispatch){

return{

setLoginState:dispatch(login(token))

}

}

export default connect(null,mapdispatchtoprops)(withRouter(Login));

这是component中的使用

const login = (token)=>{

return {

type:'login',token:token,loginStatus:true

}

}

const loginAction = (token) => dispatch =>{

if(Object.getOwnPropertyNames(token).length > 0 ){

dispatch(login(token))

}else{

return false;

}

}

export default {loginAction,login}

这是自定的action

在component在执行报错：

Uncaught TypeError: Object(...) is not a function
