我试图生成User Authentication，并从JWT Token解码User credentials，同时跟踪用户是否登录。因此，signIn方法是一个异步函数，因此，当我更新isLogged时，它总是返回false。这是下面的代码。

const useAuth = () => {
  const tokenKey = 'authToken';
  const [isLogged, setIslogged] = useState<boolean>(false);
  const [loggedUser, setloggedUser] = useState<authUsers | null>(null);
  const {user, setUser} = useContext(AuthContext);

  const singIn = async function LoginUser(token: string) {
    console.log('calling singin');
    if (isLogged && loggedUser) return;

    console.log('The USer was not logged in');

    try {
      console.log('calling singin try');
      await AsyncStorage.setItem(tokenKey, token);
      console.log('calling singin try setItem with token:', token);
      const tok = await AsyncStorage.getItem(tokenKey);
      console.log('calling singin try getItem with token:', tok);

      if (!token) return;
      console.log('Token Found Trying to decode');
      const decodedUser = convertTokenToUser(token);
      if (!decodedUser) return;
      console.log('Decode Successfull Here ', decodedUser);
      setIslogged(true);
      if (decodedUser) {
        console.log('Setting is logged to true ');
        console.log('User logged in', isLogged);
        console.log('Setting logged user done');
        setloggedUser(decodedUser);
        console.log('User logged in', decodedUser);
        setUser(decodedUser);
      }
    } catch (error) {
      setIslogged(false);
    }
  };

  useLayoutEffect(() => {
    const getTokenAndSignIn = async () => {
      const token = await getToken();
      if (token) {
        singIn(token);
      }
    };
    getTokenAndSignIn();
  }, []);

  return {isLogged, singIn, singOut, getToken, loggedUser};
};

export default useAuth;

字符串
这是我的控制台上的输出...

我希望isLogged返回true，这样我就可以呈现用户 Jmeter 板。
