sanic.response.json() 无法序列化bytes和datetime.datetime(),该如何处理？

Question

试图

# server.py
from sanic import Sanic
from sanic.response import json
from utils.dbhelper_mysql import DBHelper_MySQL

app = Sanic(__name__)
app.update_config('./config.py')
db = DBHelper_MySQL(
    app.config.get('MYSQL_HOST'),
    app.config.get('MYSQL_NAME'),
    app.config.get('MYSQL_USER'),
    app.config.get('MYSQL_PASSWORD'),
    sanic=app,
    minsize=1,
    maxsize=10
)


@app.route('/')
async def index(request):
    sql = 'SELECT * FROM categories;'
    data = await app.ctx.db.query(sql)
    print(data)
    return json(data)


if __name__ == '__main__':
    app.run()

查询方法

# dbhelper_mysql
    async def query(self, query, *parameters, **kwparameters):
        """Returns a row list for the given query and parameters."""
        if not self.pool:
            await self.init_pool()
        async with self.pool.acquire() as conn:
            async with conn.cursor() as cur:
                try:
                    await cur.execute(query, kwparameters or parameters)
                    ret = await cur.fetchall()
                except pymysql.err.InternalError:
                    await conn.ping()
                    await cur.execute(query, kwparameters or parameters)
                    ret = await cur.fetchall()
                return ret

数据表结构及内容

-- 创建分类表
CREATE TABLE IF NOT EXISTS `categories` (
    `id` BINARY ( 16 ) NOT NULL COMMENT '主键id',
    `pid` BINARY ( 16 ) COMMENT '父id,一级分类父id为空',

    `alias` VARCHAR ( 64 ) NOT NULL COMMENT '分类别名',
    `summary` TEXT COMMENT '分类描述',

    `status` CHAR ( 1 ) NOT NULL COMMENT '分类状态，H：隐藏，S：显示，T：垃圾箱，R：毁灭、彻底删除',
    `create_time` DATETIME ( 6 ) DEFAULT CURRENT_TIMESTAMP ( 6 ) COMMENT '创建时间',
    `modify_time` DATETIME ( 6 ) DEFAULT CURRENT_TIMESTAMP ( 6 ) ON UPDATE CURRENT_TIMESTAMP ( 6 ) COMMENT '修改时间',

    CONSTRAINT chk_c_level CHECK ( `level` = '1' OR `level` = '2' OR `level` = '3' ),
    CONSTRAINT chk_c_status CHECK ( `status` = 'H' OR `status` = 'S' OR `status` = 'T' OR `status` = 'R' ),
    UNIQUE KEY idx_c_name(`name`),
    UNIQUE KEY idx_c_alias ( `alias` ),
