FTP upload files Python
提问by misguided
I am trying to upload file from windows server to a unix server (basically trying to do FTP). I have used the code below
我正在尝试将文件从 Windows 服务器上传到 unix 服务器（基本上是尝试执行 FTP）。我使用了下面的代码
#!/usr/bin/python
import ftplib
import os
filename = "MyFile.py"
ftp = ftplib.FTP("xx.xx.xx.xx")
ftp.login("UID", "PSW")
ftp.cwd("/Unix/Folder/where/I/want/to/put/file")
os.chdir(r"\windows\folder\which\has\file")
ftp.storbinary('RETR %s' % filename, open(filename, 'w').write)
I am getting the following error:
我收到以下错误：
Traceback (most recent call last):
File "Windows\folder\which\has\file\MyFile.py", line 11, in <module>
ftp.storbinary('RETR %s' % filename, open(filename, 'w').write)
File "windows\folder\Python\lib\ftplib.py", line 466, in storbinary
buf = fp.read(blocksize)
AttributeError: 'builtin_function_or_method' object has no attribute 'read'
Also all contents of MyFile.pygot deleted .
的所有内容也MyFile.py被删除了。
Can anyone advise what is going wrong.I have read that ftp.storbinary is used for uploading files using FTP.
谁能告诉我出了什么问题。我读过 ftp.storbinary 用于使用 FTP 上传文件。

If you are trying to store a non-binary file(like a text file) try setting it to read mode instead of write mode.
如果您尝试存储非二进制文件（如文本文件），请尝试将其设置为读取模式而不是写入模式。
ftp.storlines("STOR " + filename, open(filename, 'r'))
for a binary file(anything that cannot be opened in a text editor) open your file in read-binary mode
对于二进制文件（任何无法在文本编辑器中打开的文件）以读取二进制模式打开文件
ftp.storbinary("STOR " + filename, open(filename, 'rb'))
also if you plan on using the ftp lib you should probably go through a tutorial, I'd recommend this articlefrom effbot.
另外，如果您打算使用 ftp lib，您可能应该阅读教程，我会推荐effbot 的这篇文章。

try making the file an object, so you can close it at the end of the operaton.
尝试使文件成为对象，以便您可以在操作结束时关闭它。
myfile = open(filename, 'w')
ftp.storbinary('RETR %s' % filename, myfile.write)
and at the end of the transfer
并在传输结束时
myfile.close()
this might not solve the problem, but it may help.
这可能无法解决问题，但可能会有所帮助。

Combined both suggestions. Final answer being
结合这两个建议。最终答案是
#!/usr/bin/python
import ftplib
import os
filename = "MyFile.py"
ftp = ftplib.FTP("xx.xx.xx.xx")
ftp.login("UID", "PSW")
ftp.cwd("/Unix/Folder/where/I/want/to/put/file")
os.chdir(r"\windows\folder\which\has\file")
myfile = open(filename, 'r')
ftp.storlines('STOR ' + filename, myfile)
myfile.close()

ftplibsupports the use of context managersso you can make it even simpler as such
ftplib支持使用上下文管理器，因此您可以使其更简单
with ftplib.FTP('ftp_address', 'user', 'pwd') as ftp, open(file_path, 'rb') as file:
ftp.storbinary(f'STOR {file_path.name}', file)
...
This way you are robust against both file and ftp issues without having to insert try/except/finally blocks. And well, it's pythonic.
通过这种方式，您无需插入 try/except/finally 块即可应对文件和 ftp 问题。好吧，它是pythonic。
PS: since it uses f-strings is python >= 3.6 only but can easily be modified to use the old .format() syntax
PS：因为它使用 f-strings 只是 python >= 3.6 但可以很容易地修改为使用旧的 .format() 语法
