python的ftp
这要看你下载用了哪个ftp库
搜到的代码
files = ftp.nlst()
for f in files:
print f
⑵ 求帮忙写个python的FTP小脚本或者批处理，复制文件到多个文件夹
有几个办法
1.如果是linux，用scp，最简单。
2.如果是windows，用共享文件夹最简单，共享完后，复制就可以
3.在目标服务器上弄一个服务，可以是FTP也可以是自己定义的socketserver。自己做服务端，也做客户端。这样权限比较大。
4.在目录服务器上安装一个标准的ftp服务器。然后客户端用python，使用ftplib
具体的用法。你自己去试验。不会花多少时间。1个小时就弄好了。
先是使用ftp的CD命令到指定的目录。然后是使用PUT命令上传文件。
不过如果是方法4，而a,b,c又不是在同一个父目录下，可能会有权限问题。
⑶ 如何在Python中使用FTP
from
ftplip
import
FTP
#
首先要引入
ftplib
这个库
#
接着，这是我自定义的几个用于操作
ftp
的函数，def
后面跟的是自定义函数名，函数体内FTP
相关的语句和函数来自上面
import
那个包，你自己体会吧：
#
初始化
FTP
连接
def
ftp_open(HOST,PORT,USERNAME,PASSWORD):
ftp=FTP()
ftp.set_debuglevel(2)
ftp.connect(host=HOST,port=PORT)
ftp.login(USERNAME,PASSWORD)
return
ftp
#
关闭
FTP
连接
def
ftp_close(ftp):
ftp.set_debuglevel(0)
ftp.quit()
#
文件上传函数，filename
可以是windows
格式包含全路径的文件
def
ftp_up(ftp,filename):
#print(ftp.getwelcome())
#ftp.cwd('xxx/www')
file_handler=open(filename,'rb')
ftp.storbinary('STOR
%s'
%
os.path.basename(filename),file_handler)
file_handler.close()
print('FTP
up
OK.')
#
文件下载函数，filename
可以是windows
格式包含全路径的文件
def
ftp_down(ftp,filename):
#print(ftp.getwelcome())
#ftp.cwd('xxx/www')
file_handler=open(filename,'wb')
ftp.retrbinary('RETR
%s'
%
os.path.basename(filename),file_handler)
file_handler.close()
print('FTP
down
OK.')
⑷ 如何用python写ftp服务器

⑸ python怎么实现管理ftp服务器文件
1. 客户端以随机非特权端口N，就是大于1024的端口，对server端21端口发起连接
2. 客户端开始监听 N+1端口；
3. 服务端会主动以20端口连接到客户端的N+1端口。
⑹ python查看FTP是否能连接成功的方法
#!/usr/local/bin/python

# python 查看FTP是否能连接成功
####################################################################
#import ftplib
##f = ftplib.FTP('192.168.100.214')
##f.login('GDATA_MEM','123456')
##ftplib.set_debuglevel(2) #打开调试级别2，显示详细信息
#data=ftplib.FTP('127.0.0.1','admin','123456')
#print data
from ftplib import FTP
def ftp_open(host='',user='',passwd=''): #打开FTP
try:
ftp=FTP()
) #打开调试级别2，显示详细信息
) #连接
data=ftp.login(user,passwd) #登录，如果匿名登录则用空串代替即可
print () #欢迎词
#print data
return 1
except:
return 0
if __name__=='__main__':
if ftp_open('127.0.0.1','admin','1234561'): #打开FTP
print "打开FTP成功"
else:
print "打开FTP失败"
⑺ 哪个ftp客户端是用python写的
使用Python写FTP客户端时，你所需要做的就是导入ftplib模块，并实例化一个ftplib.FTP类对象，所有的FTP操作（如登陆，传输文件和登出等）都要使用这个对象来完成。
以下是操作的基本步骤：
(1) 连接到服务器
(2) 登陆服务器
(3) 发出服务请求(文件交互)
(4) 退出
⑻ python如何创建FTP目录
直接使用ftplib就可以实现，其中有一个nlst功能用于查询目录，cwd用于改变目录，还有一个size功能。你这边只需要保留一个目录的镜像。如果发现有目录差异，或者是文件大小发生变更，就用retrbinary进行文件同步就可以。
⑼ python ftp连接指定服务器，并下载指定文件
ftp客户端一般只有显示、上传、下载，并没有打开文件的操作，所以你得先下载相应配置文件，在本地解析后，再继续用相关参数下载后续文件。
⑽ python ftp permission denied怎么解决
FTP 550 Permission denied 只能建文件夹，没法删除及上传文件的解决方法，需要的朋友可以参考下。
出现这种问题，
①首先检查用户对应的角色名，然后看路径设置是否正确，有没有相关的权限，如果这些都没问题，然后就尝试下面的操作：
②重起FTP服务，最好从服务里面重启(不能根本解决)；
③重新设置Server-U帐号和目录访问里的文件路径(如果还不行，尝试下面操作)；
④删除用户，重新建。
