如何在python 3中通过FTP发送StringIO? [英] How can I send a StringIO via FTP in python 3?

问题描述

我想通过FTP将文本字符串作为文件上传.

I want to upload a text string as a file via FTP.

import ftplib
from io import StringIO

file = StringIO()
file.write("aaa")
file.seek(0)


with ftplib.FTP() as ftp:
    ftp.connect("192.168.1.104", 2121)
    ftp.login("ftp", "ftp123")
    ftp.storbinary("STOR 123.txt", file)

此代码返回错误:

TypeError: 'str' does not support the buffer interface

推荐答案

这可能是python 3的一个困惑点，尤其是因为像csv这样的工具只会写str，而ftplib只接受bytes.

This can be a point of confusion in python 3, especially since tools like csv will only write str, while ftplib will only accept bytes.

您可以通过使用io.TextIOWrapper来解决此问题:

You can deal with this is by using io.TextIOWrapper:

import io
import ftplib


file = io.BytesIO()

file_wrapper = io.TextIOWrapper(file, encoding='utf-8')
file_wrapper.write("aaa")

file.seek(0)

with ftplib.FTP() as ftp:
    ftp.connect(host="192.168.1.104", port=2121)
    ftp.login(user="ftp", passwd="ftp123")

    ftp.storbinary("STOR 123.txt", file)
