React/Redux调度不会触发reducer

Question

苦苦挣扎从我的React组件派遣一个动作.这是我的第一个Redux应用程序.一切似乎都运转良好,但如果是,我不会发布这个问题.我正在使用Redux devTool来调试我的应用程序.如果我使用devTools中的调度程序,我的减速器会被触发,没有任何问题.但是,我无法从我的React组件中调度相同的操作.我在动作中添加了一个断点,看它是否被触发.我肯定是,它也返回一个有效的动作(类型和有效负载).这是我的代码:

store.js

import {createStore, applyMiddleware, compose} from 'redux'
import {createLogger} from 'redux-logger'
import thunk from 'redux-thunk'
import promise from 'redux-promise-middleware'
import reducers from './reducers/index'

const logger = createLogger()

const store = createStore(
    reducers,
    window.__REDUX_DEVTOOLS_EXTENSION__ && 
    window.__REDUX_DEVTOOLS_EXTENSION__(),
    compose(
      applyMiddleware(thunk, promise, logger)
    )
)

export default store

减速器(index.js)

import {combineReducers} from 'redux'
import userReducer from './userReducer'

const allReducers = combineReducers({
    user: userReducer
})

export default allReducers

client.js

import React from 'react'
import ReactDOM from 'react-dom'
import {Provider} from 'react-redux'
import store from './store'
import Router from './modules/router'
import MuiThemeProvider from 'material-ui/styles/MuiThemeProvider'
import getMuiTheme from 'material-ui/styles/getMuiTheme'
import CustomTheme from './modules/theme'
import injectTapEventPlugin from 'react-tap-event-plugin'
require('../scss/style.scss')

// Needed for onTouchTap
// http://stackoverflow.com/a/34015469/988941
injectTapEventPlugin();

ReactDOM.render(
  <Provider store={store}>
    <MuiThemeProvider muiTheme={CustomTheme}>
      <Router/>
    </MuiThemeProvider>
  </Provider>,
  document.getElementById('app')
);

userReducer.js

export default function (state = {loggedIn: false}, action) {
    console.log("THIS IS THE REDUCER: STATE: ", state, " - ACTION: ", action)
    switch (action.type) {
        case 'LOGIN':
            return {...state, loggedIn: action.payload}
    }
    return state;
}

userActions.js

export const login = () => {
  console.log("TEST")
    return {
        type: 'LOGIN',
        payload: true
    }
}

login.js

import React from 'react'
import ReactDOM from 'react-dom'
import LoginForm from '../containers/loginform'

class Login extends React.Component {
  render() {
    return (
      <LoginForm/>
    )
  }
}

export default Login

loginform.js

import React, {PropTypes} from 'react'
import ReactDOM from 'react-dom'
import {Redirect} from 'react-router-dom'
import {connect} from 'react-redux'
import {login} from '../actions/userActions'
import RaisedButton from 'material-ui/RaisedButton'
import TextField from 'material-ui/TextField'

class LoginForm extends React.Component {
  constructor(props) {
    super(props)
  }
  loginReq(e){
     e.preventDefault()
     this.props.login()
  }
  render() {
    return (
      <div>
        <form className='login-form-container' onSubmit=    {this.loginReq.bind(this)}>
          <div className='login-form-row'>
            <TextField
              ref='email'
              hintText='Email'
              floatingLabelText='Email'
              className='login-form-field'/>
          </div>
          <div className='login-form-row'>
            <TextField
              ref='password'
              hintText='Password'
              floatingLabelText='Password'
              type='password'
              className='login-form-field'/>
          </div>
          <div className='login-form-row'>
            <RaisedButton
              type= 'submit'
              label='Login'
              className='login-form-button'/>
          </div>
        </form>
      </div>
    )
  }
}

const mapStateToProps = (state) => {
    return {
        loggedIn: state.user.loggedIn
    }
}

const mapDispatchToProps = (dispatch) => {
    return {
      login: () => dispatch(login())
    }
}

export default connect(mapStateToProps, mapDispatchToProps)(LoginForm)

请你能给我一些指导,告诉我如何进行调试,找出为什么这个调度不起作用.我已经尝试将动作对象直接添加到该调度函数中.仍然没有运气.我在控制台中没有任何错误.我的console.logs仅在视图呈现时以及单击登录提交按钮时打印.

终于找到了我的问题.我的中间件实现导致了这个问题.我传球promise不正确.应该:

import {createStore, applyMiddleware} from 'redux'
import {composeWithDevTools} from 'redux-devtools-extension'
import {createLogger} from 'redux-logger'
import thunk from 'redux-thunk'
import promise from 'redux-promise-middleware'
import reducers from './reducers/index'

const logger = createLogger()

const middleware = applyMiddleware(promise(), logger, thunk)

const store = createStore(reducers, composeWithDevTools(middleware))

export default store

还发现redux-devtools-extension对Redux devTools来说更干净.
