嗨，我是新的redux和身份验证。我正在创建一个React/redux应用程序，用户可以登录，并能够通过提交一个表单添加一个故事。我能够登录，但当我到达故事创建页面，我点击提交，我得到一个POST http://localhost:3000/api/v1/stories 401 (Unauthorized)错误。我正在使用一个API登录，该API在登录时提供一个令牌。然后我将用户名和令牌保存到sessionstorage。但我如何修复这个错误？
App.js

import './App.scss';
import Login from './components/Login';
import { Router, Switch, Route, NavLink } from 'react-router-dom';
import PrivateRoute from './utils/PrivateRoute';
import CreateStory from './components/CreateStory';
import history from './utils/history';

function App() {

  return (
    <div className="App">

      <Router history={history}>
        <Switch>
          <Route exact path="/" component={Login} />
          <PrivateRoute path="/user" component={CreateStory}/>

        </Switch>
      </Router>
    </div>

您必须将auth token从sessionStorage传递到您要将故事发布到的API的头部：-

const token = sessionStorage.getItem('token'); //Add this line

return fetch('http://localhost:3000/api/v1/stories', {
    method: 'POST',
    headers: {  
      Accept: 'application/json',
      'Content-Type': 'application/json',
       Authorization: `Bearer ${token}` //Add this line
    },
    body: JSON.stringify(storyInput),
  })

在我的情况下，GET，PUT和POST工作，但唯一的问题是与POST。我也尝试通过中间件。但不去中间件，直接返回401状态代码。
然后，我只需更改端点的名称，它就可以为我工作。
