带有装饰器的烧瓶 MethodView 给出错误

Question

也许我做错了什么。我正在尝试使用flask-security-too auth_required 和flask 的MethodView，如https://flask.palletsprojects.com/en/1.1.x/views/#decorating-views 所述，当我尝试访问该页面时会引发异常。蟒蛇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',])

异常

Answer 1

好的 - 简单的解决方案 - 因为 auth_required 需要参数 - 你需要：

decorators = [auth_required()]

抱歉 - 我建议传入 None - 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”）都可以正常工作。
