Question

也许我做错了什么。我正在尝试将flask-security-too auth_required与烧瓶的MethodView配合使用，如https://flask.palletsprojects.com/en/1.1.x/views/#decorating-views所述，当我尝试访问该页面时，出现了异常。 python 3.6.8

from flask_security import auth_required

class RunningRoutesAdmin(MethodView):
    decorators = [auth_required]

    def get(self):
        return render_template('admin.jinja2',
                               pagename='Admin Home')

admin_view = RunningRoutesAdmin.as_view('admin')
app.add_url_rule('/admin/', view_func=admin_view, methods=['GET',])

例外

好-简单的解决方案-由于auth_required需要参数-您需要：

decorators = [auth_required()]

对不起-我建议传递“无”-这当然是不正确的。不传递任何内容或传递可接受的方法列表（例如“会话”，“令牌”）都可以。
