我真的很难将一个简单的.txt文件上传到 FTP 服务器。我的桌面上有一个文件夹，其中包含两个文件：text.txt和upload_to_ftp.py.
我试过这些：
FTP文件上传
Python脚本通过FTP上传文件
但似乎都不起作用。
我已经重写了很多次代码，我一直在努力，我不断收到错误，例如：
sftp = ftplib.FTP('REMOTEFTPSITE.com', 'MYUSERNAME', 'MYPASSWORD')
File "C:\Python27\lib\ftplib.py", line 117, in __init__
self.connect(host)
File "C:\Python27\lib\ftplib.py", line 135, in connect
self.welcome = self.getresp()
File "C:\Python27\lib\ftplib.py", line 210, in getresp
resp = self.getmultiline()
File "C:\Python27\lib\ftplib.py", line 196, in getmultiline
line = self.getline()
File "C:\Python27\lib\ftplib.py", line 183, in getline
line = self.file.readline()
File "C:\Python27\lib\socket.py", line 447, in readline
data = self._sock.recv(self._rbufsize)
error: [Errno 10054] An existing connection was forcibly closed by the remote host
任何帮助都会很棒！提前致谢。
