Javascript 反应：动作必须是普通对象

我有以下项目结构-

我有GlobalStore.js，其中有以下代码：-

import React from 'react'

const GlobalContext=React.createContext();
const GlobalProvider=GlobalContext.Provider;
const GlobalConsumer=GlobalContext.Consumer;


export  {GlobalProvider,GlobalConsumer}

const VERIFY_CREDENTIALS ='VERIFY_CREDENTIALS'
export function VerifyCredentials()
{
    return{
        type :VERIFY_CREDENTIALS
    }
}

import Axios from "axios";
import { VerifyCredentials } from "./Login_Action";

const initialState={
    userName:"",
    password:"",
    isVarified:false
}
const url='http://localhost:52016/api/values/';
export const  LoginReducer=(state=initialState,action)=>{
    switch (action.type) {
        case 'VERIFY_CREDENTIALS':
            
            Axios.get(url)
                 .then(x=>{
                     alert(x.data);

                 })
    
        default:
            break;
    }
}

import { createStore } from 'redux';

}

export default App;

npm install --save redux-thunk

import { applyMiddleware } from 'redux';
import thunk from 'redux-thunk';

export const  store=createStore(LoginReducer,applyMiddleware(thunk));

LoginReducers/Login\u Action.js，代码如下-

  );
}

export default App;

npm install --save redux-thunk

import { applyMiddleware } from 'redux';
import thunk from 'redux-thunk';

export const  store=createStore(LoginReducer,applyMiddleware(thunk));

从“/logo.svg”导入徽标；
导入“/App.css”；
从“./Components/Login”导入登录名；
从“/GlobalStorage/store”导入{store}；
从“/GlobalStore”导入{GlobalProvider，GlobalConsumer}”；
函数App（）{
返回(

}
导出默认应用程序；

我得到以下错误：-

import React from 'react'

const GlobalContext=React.createContext();
const GlobalProvider=GlobalContext.Provider;
const GlobalConsumer=GlobalContext.Consumer;


export  {GlobalProvider,GlobalConsumer}

const VERIFY_CREDENTIALS ='VERIFY_CREDENTIALS'

  );
}

export default App;

npm install --save redux-thunk

import { applyMiddleware } from 'redux';
import thunk from 'redux-thunk';

export const  store=createStore(LoginReducer,applyMiddleware(thunk));

请建议可以进行哪些更改以解决此错误

另外，请建议是否建议在我通过

GlobalProvider

共享

store

的地方使用上述代码结构-

import React from 'react'

const GlobalContext=React.createContext();
const GlobalProvider=GlobalContext.Provider;
const GlobalConsumer=GlobalContext.Consumer;


export  {GlobalProvider,GlobalConsumer}

const VERIFY_CREDENTIALS ='VERIFY_CREDENTIALS'

  );
}

export default App;

npm install --save redux-thunk

import { applyMiddleware } from 'redux';
import thunk from 'redux-thunk';

export const  store=createStore(LoginReducer,applyMiddleware(thunk));

还在store.js中添加了以下代码-

const GlobalConsumer=GlobalContext.Consumer;


export  {GlobalProvider,GlobalConsumer}

此外，您的减速机应该是纯功能的，并让您的员工采取以下行动：

行动

import Axios from "axios";

const VERIFY_CREDENTIALS ='VERIFY_CREDENTIALS';
const ERROR_CREDENTIALS='ERROR_CREDENTIALS';

export function VerifyCredentials(username,password)
{
  return Axios.post(url,{username,password})
    .then(x=>{
        {type :VERIFY_CREDENTIALS,payload:{userData:x.data, isVarified:true} }
    })
    .catch((err) => {type :ERROR_CREDENTIALS});
}

减速器

import { VERIFY_CREDENTIALS ,ERROR_CREDENTIALS} from "./Login_Action";

const initialState={
    userData:"",
    isVarified:false
}
const url='http://localhost:52016/api/values/';
export const  LoginReducer=(state=initialState,action)=>{
    switch (action.type) {
        case VERIFY_CREDENTIALS:
            return action.payload;
        case ERROR_CREDENTIALS:
            return state;
        default:
            return state;
    }
}

此外，您的减速机应为纯功能减速机，并对您的员工进行如下操作：

行动

import Axios from "axios";

const VERIFY_CREDENTIALS ='VERIFY_CREDENTIALS';
const ERROR_CREDENTIALS='ERROR_CREDENTIALS';

export function VerifyCredentials(username,password)
{
  return Axios.post(url,{username,password})
    .then(x=>{
        {type :VERIFY_CREDENTIALS,payload:{userData:x.data, isVarified:true} }
    })
    .catch((err) => {type :ERROR_CREDENTIALS});
}

减速器

import { VERIFY_CREDENTIALS ,ERROR_CREDENTIALS} from "./Login_Action";

const initialState={
    userData:"",
    isVarified:false
}
const url='http://localhost:52016/api/values/';
export const  LoginReducer=(state=initialState,action)=>{
    switch (action.type) {
        case VERIFY_CREDENTIALS:
            return action.payload;
        case ERROR_CREDENTIALS:
            return state;
        default:

你的代码是非常错误的！！！ 请注意以下所有事项。也请阅读文档-以便编写更好的代码 使用

react redux

library-对于创建异步操作，使用

redux thunk

import   {Provider} from "react-redux"; // you need this
import logo from './logo.svg';
import './App.css';
import Login from './Components/Login';
import { store } from "./GlobalStorage/store";

function App() {
  return (
    <div className="App">
      <Provider store={store}> 
         <Login/>
      </Provider>
    </div>
  );
