无法使用aiohttp发出异步请求

请移动所有数据库访问代码( SELECT ...

def sync_db_request(container_id):
    data = mysqlcon("SELECT date,moves,location,vessel,voyage,current_status FROM container_status WHERE date_current in (SELECT max(date_current) FROM container_status) and company_id={0}".format(container_id),"rpa")
    a = {"Result":[]}
    if data == ():
        pass
    else:
        for i in data:
            a["Result"].append(i)
    return a

async def Logistic(request):
    container_id = request.query['container_id']
    company = request.query['company']
    a = await request.loop.run_in_executor(None, sync_db_request, container_id)
    return web.Response(text=json.dumps(a),headers={'ACCESS-CONTROL-ALLOW-ORIGIN':'*'})
