python ftp服务器显示“150文件状态没问题.即将打开数据连接.“

我使用ftp命令通过cmd登录.

PL帮助.

这是服务器代码：

import os
import sqlite3
from pyftpdlib import ftpserver


def main():

    authorizer = ftpserver.DummyAuthorizer()

    ftp_auth_table="H:ftp_auth_table1.db"
    connection=sqlite3.connect(ftp_auth_table,isolation_level=None)
    cursor=connection.cursor()
    cursor.execute('''SELECT * FROM ftp_auth_table1''')
    entry=cursor.fetchall()
    # change os.gtcwd() with ftp_actv_dir
    for x in entry:
        authorizer.add_user(x[1],x[2],"H:/MS EVERYTHING",perm='elradfmwM')


    # Instantiate FTP handler class
    handler = ftpserver.FTPHandler
    handler.authorizer = authorizer


    handler.banner = "pyftpdlib %s based ftpd ready." %ftpserver.__ver__


    address = ('127.0.0.1',21)
    ftpd = ftpserver.FTPServer(address,handler)

    ftpd.max_cons = 256
    ftpd.max_cons_per_ip = 5

    # start ftp server
    ftpd.serve_forever()

if __name__ == '__main__':
    main()
