Python 将数据从数据库存储到json文件

所以我创建了数据库，将一些数据存储到表中，并希望将其导入JSON格式，以便使用一些JS脚本将其可视化。但是当我试图将其写入JSON时，我得到了

ValueError:无法解码任何JSON对象

代码如下：

from PyBambooHR import PyBambooHR
import sqlalchemy
from sqlalchemy import Column, Integer, String
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker
import json


Base = declarative_base()


class EmployeeData(Base):

    __tablename__ = 'employee_data'
    id = Column(Integer, primary_key=True)
    name = Column(String(120))
    department = Column(String(120))
    jobTitle = Column(String(120))
    email = Column(String(120))

    def __init__(self, name, department, jobTitle, email):
        self.name = name
        self.department = department
        self.jobTitle = jobTitle
        self.email = email


engine = sqlalchemy.create_engine('sqlite:///employee_db.db')

connection = engine.connect()

Base.metadata.create_all(engine)


bamboo = PyBambooHR(subdomain='domain', api_key='apikey')

session_factory = sessionmaker(engine)
session = session_factory()

employees = bamboo.get_employee_directory()
employees_list = [EmployeeData(name=item['displayName'], department=item['department'], jobTitle=item['jobTitle'], email=item['workEmail']) for item in employees]

avoid_duplicates = list(connection.execute('select * from employee_data'))

for i in employees_list:
    if i.name not in [j[1] for j in avoid_duplicates]:
        session.add(i)

session.commit()
session.close()
connection.close()

with open('employee_db.db', 'rb') as input_file:
    content = json.load(input_file)
with open('employee_data.json', 'wb') as output_file:
    json.dump(content,output_file, indent=1)

嗯，似乎很明显：

with open('employee_db.db', 'rb') as input_file:
    content = json.load(input_file)

您是从哪里得到sqlite数据库将采用json格式的巴洛克想法的

好的，如果有人需要它来与BambooHR合作，这里是工作代码

url=“具有api密钥的请求”必须如下所示 ''

你可以从BambooHR获得你的API密钥，方法是点击右角的照片，然后点击API密钥

你试过检查数据库的编码吗？认为它可以使用数据库中的字符串来填充jsonOh是的，我的错，显然json解析器应该知道如何读取任意二进制格式，并将其转换为你心目中的确切json输出格式。。。
