FTP Server, pyftplib, a lightweight and portable FTP server ready to use

Create FTP:

FTP便携服务器.py

#!/usr/bin/env python
import traceback
import os

from pyftpdlib.authorizers import DummyAuthorizer
from pyftpdlib.handlers import FTPHandler
from pyftpdlib.servers import FTPServer

import socket


os.system('chcp 936')  ## 指定本次CMD窗口编码：gbk

hostname = socket.gethostbyname(socket.gethostname()) # 获取某一网络分配到本机的IP地址
port = 2121

username = 'username'
password = 'password'





"""A basic FTP server which uses a DummyAuthorizer for managing 'virtual
users', setting a limit for incoming connections and a range of passive
ports.
"""

def main():

    '''
    add_user(username, password, homedir, perm="elr", msg_login="Login successful.", msg_quit="Goodbye.")
    Add a user to the virtual users table. AuthorizerError exception is raised on error conditions such as insufficient permissions or duplicate usernames. Optional perm argument is a set of letters referencing the user’s permissions. Every letter is used to indicate that the access rights the current FTP user has over the following specific actions are granted. The available permissions are the following listed below:

    Read permissions:

    "e" = change directory (CWD, CDUP commands)
    "l" = list files (LIST, NLST, STAT, MLSD, MLST, SIZE commands)
    "r" = retrieve file from the server (RETR command)
    Write permissions:

    "a" = append data to an existing file (APPE command)
    "d" = delete file or directory (DELE, RMD commands)
    "f" = rename file or directory (RNFR, RNTO commands)
    "m" = create directory (MKD command)
    "w" = store a file to the server (STOR, STOU commands)
    "M" = change file mode / permission (SITE CHMOD command) New in 0.7.0
    "T" = change file modification time (SITE MFMT command) New in 1.5.3
    Optional msg_login and msg_quit arguments can be specified to provide customized response strings when user log-in and quit. The perm argument of the add_user() method refers to user’s permissions. Every letter is used to indicate that the access rights the current FTP user has over the following specific actions are granted.


    add_anonymous(homedir, **kwargs)
    Add an anonymous user to the virtual users table. AuthorizerError exception is raised on error conditions such as insufficient permissions, missing home directory, or duplicate anonymous users. The keyword arguments in kwargs are the same expected by add_user() method: perm, msg_login and msg_quit. The optional perm keyword argument is a string defaulting to “elr” referencing “read-only” anonymous user’s permission. Using a “write” value results in a RuntimeWarning.

Note:

Log in to FTP using Windows File Explorer to display garbled Chinese characters

Because Windows File Explorer uses gbk encoding, and pyftpdlib uses utf8 encoding by default, garbled characters will appear when displaying Chinese

solution:

The pyftpdlib package filesystems.pywith handlers.pyall utf8all changed gbk, changed GBK coding is about pyftpdlib
