問題描述

我的問題是如何將 CSV 文件發送到 FTP 服務器.如您所見，以下腳本是我當前的代碼:

My question is How can I send a CSV file to an FTP server. As you can see, the following script is the current code of mine:

代碼示例:

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

這是一個 Django 視圖，我不想將 CSV 保存在本地系統上，我只想將其直接發送到 FTP 服務器.誰能幫幫我?

This is a Django view, I don't want to save the CSV on my local system, I just want to directly send it to an FTP server. Can anyone help me?

推薦答案

將 CSV 文件寫入內存中類似文件的對象(例如 BytesIO) 并上傳:

Write the CSV file to an in-memory file-like object (e.g. BytesIO) and upload that:

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)
