Flask 学习-82.Flask-RESTX使用reqparse 解析器校验枚举类型choices 参数

    def post(self):
        # 校验入参
        parser = reqparse.RequestParser()
        parser.add_argument('username', required=True, type=str,  nullable=False, help='username is required')
        parser.add_argument('password', required=True, type=str,  nullable=False, help='password is required')
        parser.add_argument('sex', choices=["男", "女"],  type=str, help='sex invalid')
        args = parser.parse_args()
