在石墨烯中使用具有多个分解器的相同连接

Question

我有这样的代码，

# SWAMI KARUPPASWAMI THUNNAI

import jwt
import graphene
from flask import request
from auth.helper import medease_token
from database.get_connection import get_connection
from flask_graphql import GraphQLView


class CredentialInformation(graphene.ObjectType):
    """
    graphene object type to get the personal information about the user
    """

    country_code = graphene.String()
    phone = graphene.String()
    verified = graphene.Int()

    @medease_token
    def resolve_country_code(self, root):
        customer_token = request.headers["x-access-token"]
        decoded_token = jwt.decode(customer_token, verify=False)
        customer_id = decoded_token["customer_id"]
        try:
            connection = get_connection()
            cursor = connection.cursor()
            cursor.execute("select country_code from customer_credential where id=%s limit 1", (customer_id, ))
            result = cursor.fetchone()
            return result["country_code"]
        finally:
            cursor.close()
            connection.close()

    @medease_token
    def resolve_phone(self, root):
        customer_token = request.headers["x-access-token"]
        decoded_token = jwt.decode(customer_token, verify=False)
        customer_id = decoded_token["customer_id"]
        try:
            connection = get_connection()
            cursor = connection.cursor()
            cursor.execute("select phone from customer_credential where id=%s limit 1", (customer_id, ))
            result = cursor.fetchone()
            return result["phone"]
        finally:
            cursor.close()
            connection.close()

    @medease_token
    def resolve_verified(self, root):
        customer_token = request.headers["x-access-token"]
        decoded_token = jwt.decode(customer_token, verify=False)
        customer_id = decoded_token["customer_id"]
        try:
            connection = get_connection()
            cursor = connection.cursor()
            cursor.execute("select verified from customer_credential where id=%s limit 1", (customer_id,))
            result = cursor.fetchone()
            return result["verified"]
        finally:
            cursor.close()
            connection.close()


def credential_information_wrapper():
    return GraphQLView.as_view("graphql", schema=graphene.Schema(query=CredentialInformation))

对于Python graphql使用flask-graphql和graphene。代码绝对可以正常工作，但是我想我在这里遗漏了一些东西，因为我需要在每个解析器中打开新的连接，并且我需要再次编写相同的查询，以便进行数据复制，这是正确的做法吗？缺少什么？

任何帮助将不胜感激！预先谢谢你。
