我正在做一个flash消息，这样当用户注册时，它会显示一条消息“用户注册成功！”，但当我尝试登录时，它会显示一条消息“请登录以访问该页面”，即使我已经登录。我如何解决这个问题？
这是登录路线

@bp.route("user_settings/login", methods=["GET","POST"])
def login():
    if current_user.is_authenticated:
        return redirect(url_for('main.user_settings'))
    form = LoginForm()
    if form.validate_on_submit():
        user = User.query.filter_by(username=form.username.data).first()
        if user is None or not user.check_password(form.password.data):
            return redirect(url_for("auth.login"))
        login_user(user, remember=form.remember_me.data)
        next_page = request.args.get("next")
        if not next_page or url_parse(next_page).netloc != '':
            next_page = url_for("main.user_settings")
        return redirect(next_page)
    return render_template("auth/login.html", title='Log In', form=form)

这是注册路径

@bp.route("user_settings/register", methods=['GET', 'POST'])
@login_required
def register():
    form = RegistrationForm()
    if form.validate_on_submit():
        user = User(username=form.username.data, password_string=form.password.data, access_level=form.access_level.data)
        user.set_password(form.password.data)
        db.session.add(user)
        db.session.commit()
        flash("User Successfully Registered!", "success")
        return redirect(url_for('main.admin_mid', mode="admin")) 
    return render_template("auth/register.html", title="Register User", form = form)

HTML模板

{% with messages = get_flashed_messages() %} {% if messages %} {% for
    message in messages %}
    <div class="alert alert-success alert-dismissible fade show" role="alert">
      {{ message }}
      <button type="button" class="btn-close" data-bs-dismiss="alert"></button>
    </div>
    {% endfor %} {% endif %} {% endwith %}
