如何使用python直接创建一个csv文件到ftp服务器？

Question

我有一个代码来创建一个 csv 文件并且可以将它上传到 ftp 服务器

with open(csv_file, 'w') as csvfile:
    writer = csv.DictWriter(csvfile, fieldnames=csv_columns1) #csv_columns1 is a list of value to become  as heading
    writer.writeheader()
    for data in vals['details']:# values for the header
        writer.writerow(data)
    writer = csv.DictWriter(csvfile, fieldnames=csv_columns2)#csv_columns1 is a list of value to become  as heading
    writer.writeheader()
    writer = csv.DictWriter(csvfile, fieldnames=csv_columns)#csv_columns1 is a list of value to become  as heading
    writer.writeheader()
    for data in vals['OrderLine']:# values for the header
        writer.writerow(data)
        print(os.system('pwd'))

     Output_Directory = "ftp_path_to_store_file"
     username = "ftp_user_names"
     password = "ftp_password"
     ftp_ip = "ftp_host_ip"
     a1 = 'STOR %s.csv' % (order.name)

     try:
        ftp = FTP(ftp_ip)
        ftp.login(username, password)
        ftp.cwd(Output_Directory)
        with open(csv_file, "rb") as f:
             ftp.storbinary('STOR ' + os.path.basename(csv_file), f)

但我需要的是没有在我的电脑上创建文件我想直接创建一个文件到 ftp 服务器

任何帮助，将不胜感激

您可以让 csv writer 写入io.StringIO对象，然后io.BytesIO在将其文本值编码为字节后将输出转换为对象：

import io
csvfile = io.StringIO()
writer = csv.DictWriter(csvfile, fieldnames=csv_columns1) #csv_columns1 is a list of value to become  as heading
writer.writeheader()
for data in vals['details']:# values for the header
    writer.writerow(data)
writer = csv.DictWriter(csvfile, fieldnames=csv_columns2)#csv_columns1 is a list of value to become  as heading
writer.writeheader()
writer = csv.DictWriter(csvfile, fieldnames=csv_columns)#csv_columns1 is a list of value to become  as heading
writer.writeheader()
for data in vals['OrderLine']:# values for the header
    writer.writerow(data)
    print(os.system('pwd'))

Output_Directory = "ftp_path_to_store_file"
username = "ftp_user_names"
password = "ftp_password"
ftp_ip = "ftp_host_ip"
a1 = 'STOR %s.csv' % (order.name)

try:
    ftp = FTP(ftp_ip)
    ftp.login(username, password)
    ftp.cwd(Output_Directory)
    ftp.storbinary('STOR ' + os.path.basename(csv_file), io.BytesIO(csvfile.getvalue().encode()))
