Question

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

lm.out <- lm(Humerus ~ $Radius,data=new_data)
newx = seq(min(new_data$Radius),max(new_data$Humerus),by = 0.05)
conf_interval <- predict(lm.out, newdata=data.frame(Radius=newx), interval="confidence",level = 0.95)
plot(new_data$Radius, new_data$Humerus, xlab="Radius", ylab="Humerus", main="Regression")
abline(lm.out, col="lightblue")
lines(newx, conf_interval[,2], col="blue", lty=2)
lines(newx, conf_interval[,3], col="blue", lty=2)

此过程是从我使用FlaskResfutl开发的Python Web服务中调用的，以创建通用控件，这是代码：

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

但是在执行它时，会产生以下错误：

import cx_Oracle
import json
from app import APP
import log
import graypy
import database
from flask_restplus import Api, Resource, fields

with open('./config/config_countries.json', 'r') as config_file:
    config = json.load(config_file)

log.init()

#Se inicializa la base de datos
#Importando de database la conexión a la BD
database.init()

#Invoca al archivo de configuración
with open('./config/config_countries.json', 'r') as config_file:
    config = json.load(config_file)

with open('./config/config_general.json', 'r') as config_file:
    config_general = json.load(config_file)

srv_name = config["CONFIG"]["LOG_TAG"]
db_str = config["CONFIG"]["DB"]
max_return = config_general["CONFIG"]["MAX_RETURN"]
limite = config["CONFIG"]["LIMIT_PER_SECOND"]
api = Api(APP, version='1.0', title=srv_name,
          description='getCountries de Callejero Predictivo\n'
                      'Conexión a BD:' + db_str + '\n'
                      'Cantidad máxima de invocaciones por segundo:' + limite)

ns = api.namespace('getCountry', description='getCountries de Callejero Predictivo')


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


@ns.route('/<string:country>')
@ns.response(200, 'Success')
@ns.response(404, 'Not found')
@ns.response(429, 'Too many request')
@ns.param('country', 'Introducir Cadena de Caracteres para el Pais')
class getCountryClass(Resource):
    @ns.doc('getCountry')
    @ns.marshal_list_with(md_respuesta)
    def post(self, country):
        try:
            cur = database.db.cursor()
            listOutput = cur.var(cx_Oracle.STRING)
            cur.callproc('PREDICTIVO.get_pais', (country, max_return, listOutput))
        except Exception as e:
            database.init()
            if database.db is not None:
                log.err('Reconexion OK')
                cur = database.db.cursor()
                listOutput = cur.var(cx_Oracle.STRING)
                cur.callproc('PREDICTIVO.get_pais', (country, max_return, listOutput))
            else:
                log.err('Sin conexion a la base de datos')
                listOutput = None


        return listOutput, 200

，我找不到解决方法。有人可以给我提示解决的线索吗？

查看https://flask-restplus.readthedocs.io/en/stable/_modules/flask_restplus/swagger.html和https://flask-restplus.readthedocs.io/en/stable/quickstart.html

注册的模型不能是字典，您需要一个模型，尝试替换

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

通过

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

Python麻烦的麻烦
