有一个拦截器，您需要在其中处理 401（未经授权）错误

 return next.handle(request)
      .pipe(catchError(error => {
          if (error instanceof HttpErrorResponse && error.status === 401) {
                 return this.handle401Error(req, next);
}
              return throwError(error);

由于某种原因，401 没有被捕获，尽管它在浏览器中可见。可能是什么问题？ 铬开发输出

      <ul>
        <li><Link to="/">Home</Link></li>
        <li><Link to="/about">About</Link></li>
        <li><Link to="/topics">Topics</Link></li>
      </ul>

      <hr/>

      <Route  component={Home}>
        <Route path="about" component={About}/>
        <Route path="topics" component={Topics}/>
      </Route>
    </div>
  </Router>

const Home = () => (
  <div>
    <h2>Home</h2>
