在我的表格中，我執行以下操作import useReactRouter from 'use-react-router';const { history } = useReactRouter();onSubmit={async (values, { setSubmitting }) => {  setSubmitting(true);  fetch('/register', {    method: 'POST',    body: JSON.stringify(values),    headers: {      'Content-Type': 'application/json'    }  })    .then(res => res.json())    .then(async response => {      setSubmitting(false);      if (!response.success) return showAlert();      await login();      history.push('/profile');    })登錄這樣做：export const AuthContext = createContext<any>(null);const AuthProvider = ({ children }: ProviderProps): JSX.Element => {  const [auth, setAuth] = useState({    isAuthenticated: false,    user: null  });  const login = () => {    fetch('/me')      .then(res => res.json())      .then(response => {        if (response) setAuth({ isAuthenticated: true, user: response });      });  };  const logout = () => {    fetch('/logout').then(() =>      setAuth({ isAuthenticated: false, user: null })    );  };  return (    <AuthContext.Provider      value={{        state: {          auth        },        actions: {          login,          logout        }      }}    >      {children}    </AuthContext.Provider>  );};注冊后，`isAuthenticated 在下面的代碼中返回true，但導航到另一個頁面后又返回false，可能是什么問題？const PrivateRoute = (props: PrivateRouteProps) => {  const { component: Component, ...rest } = props;  const {    state: {      auth: { isAuthenticated }    }  } = useContext(AuthContext);  console.log(isAuthenticated);<Router>  <div>    <AuthProvider>      <Header />      <Route exact path="/" component={Home} />      <MuiPickersUtilsProvider utils={LocalizedUtils} locale={nlLocale}>        <Route exact path="/register" component={Register} />      </MuiPickersUtilsProvider>      <PrivateRoute exact path="/profile" component={Profile} />    </AuthProvider>  </div></Router>我正在尋找一種解決方案來在登錄所有頁面后保持 isAuthenticated 狀態，即使在單擊另一個鏈接或調用 history.push 之后
