Python大摇大摆

Question

我有一个oracle过程，当接收到一些参数时，抛出一个JSON格式的字符串，如下所示：

{"list_pais": [ {"pais":"URUGUAY"},{"pais":"ARGENTINA"},{"pais":"PARAGUAY"},{"pais":"VENEZUELA"}] }

这个过程是从Python中的一个webservice调用的，我用FlaskResfutl开发它来创建swagger，这是de代码：

但执行时会产生以下错误：

我不知道怎么解决它。 有人能给我一些线索来解决这个问题吗？在

看https://flask-restplus.readthedocs.io/en/stable/_modules/flask_restplus/swagger.html和{a2}

注册的模型不能是dict，您需要一个模型，请尝试替换

md_respuesta = {'pais': fields.String(required=True, description='Agrupador de Paises'), 'list_pais': fields.Nested(fields.String)}

通过
