如何将 CSV 文件直接发送到 FTP 服务器

我的问题是如何将 CSV 文件发送到 FTP 服务器。如您所见，以下脚本是我当前的代码：

代码示例：

def download_outage_info_all(request):

    upload_data = download_data_form(request.POST)
    if upload_data.is_valid():
        print("valid")
        start = upload_data.cleaned_data['start_date_time']

        end = upload_data.cleaned_data['end_date_time']
        print(start, '-', end)

        start_timestamp = datetime.strptime(
            start, '%Y-%m-%d %H:%M')
        end_timestamp = datetime.strptime(
            end, '%Y-%m-%d %H:%M')

    try:
        info = planned_outages.objects.filter(
            start_timestamp__gte=start_timestamp, end_timestamp__lte=end_timestamp).values()
    except Exception as e:
        print("EXCEPTION", e)
        print("**** Data not found *** ")

    filename_date_part = datetime.now().strftime("%Y%m%d%H%M")

    response = HttpResponse(content_type='text/csv')

    response['Content-Disposition'] = 'attachment;filename=m_availability_' + \
                                      filename_date_part + '.csv'
    writer = csv.writer(response, delimiter=';')

    writer.writerow(['starts YYYY-mm-dd HH:MM:SS', 'time_zone',
                     'ends YYYY-mm-dd HH:MM:SS', 'asset id', 'availability type', 'PowerKW'])

    for x in info:

        try:
            unit_mw = unit_details.objects.get(
                unit_id=x['unit_id_id'])


            # prints to csv file
            writer.writerow([x['start_timestamp'], 'UTC',
                             x['end_timestamp'], unit_mw.unit_name,x['availability_type'], x['capacity_kw']])

        except Exception as e:
            print("EXCEPTION", e)
            print("**** Data not found for unit_mw*** ")

    return response

这是 Django 视图，我不想将 CSV 保存在本地系统上，我只想将其直接发送到 FTP 服务器。谁能帮我？

将 CSV 文件写入内存中的类似文件的对象（例如BytesIO）并上传：

from ftplib import FTP
from io import BytesIO
import csv

flo = BytesIO() 
writer = csv.writer(flo, delimiter=';')

writer.writerow(...)

ftp = FTP('ftp.example.com')
ftp.login('username', 'password')

flo.seek(0)
ftp.storbinary('STOR test.csv', flo)
