废话就不说了，这里就给出我封装的 ftp 工具类，有兴趣的自己看一下吧–_--

然后使用代码在这里
from tel.api.ftp_utils import ftp as FTP
# Download zip_file from FTP
ip = CONF.upf.ip
port = CONF.upf.port
user = CONF.upf.user
password = CONF.upf.password
ftp = FTP(ip, port, user, password)
remote_path = "raypick/5GC_GD_HUAWEI.zip"
local_path = CONF.upf.local_path
tmp_file_path = local_path + remote_path.split('/')[-1]
ftp.ftp_download(remote_path, local_path)
关于 ftp，部分功能解释如下
ftp登陆连接
from ftplib import FTP #加载ftp模块
ftp=FTP() #设置变量
ftp.set_debuglevel(2) #打开调试级别2，显示详细信息
ftp.connect("IP","port") #连接的ftp sever和端口
ftp.login("user","password") #连接的用户名，密码
print ftp.getwelcome() #打印出欢迎信息
ftp.cmd("xxx/xxx") #进入远程目录
bufsize=1024 #设置的缓冲区大小
filename="filename.txt" #需要下载的文件
file_handle=open(filename,"wb").write #以写模式在本地打开文件
ftp.retrbinaly("RETR filename.txt",file_handle,bufsize) #接收服务器上文件并写入本地文件
ftp.set_debuglevel(0) #关闭调试模式
ftp.quit() #退出ftp
ftp相关命令操作
ftp.cwd(pathname) #设置FTP当前操作的路径
ftp.dir() #显示目录下所有目录信息
ftp.nlst() #获取目录下的文件
ftp.mkd(pathname) #新建远程目录
ftp.pwd() #返回当前所在位置
ftp.rmd(dirname) #删除远程目录
ftp.delete(filename) #删除远程文件
ftp.rename(fromname, toname)#将fromname修改名称为toname。
ftp.storbinaly("STOR filename.txt",file_handel,bufsize) #上传目标文件
ftp.retrbinary("RETR filename.txt",file_handel,bufsize) #下载FTP文件
