Ⅰ 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。

Ⅱ 有大神知道怎么使用python 往ftp服务器上连续上传下载多张图片吗
例：下载、上传文件
#coding:utf-8
fromftplibimportFTP
importtime
importtarfile
importos
#!/usr/bin/python
#-*-coding:utf-8-*-
fromftplibimportFTP
defftpconnect(host,username,password):
ftp=FTP()
#ftp.set_debuglevel(2)
ftp.connect(host,21)
ftp.login(username,password)
returnftp
#从ftp下载文件
defdownloadfile(ftp,remotepath,localpath):
bufsize=1024
fp=open(localpath,'wb')
ftp.retrbinary('RETR'+remotepath,fp.write,bufsize)
ftp.set_debuglevel(0)
fp.close()
#从本地上传文件到ftp
defuploadfile(ftp,remotepath,localpath):
bufsize=1024
fp=open(localpath,'rb')
ftp.storbinary('STOR'+remotepath,fp,bufsize)
ftp.set_debuglevel(0)
fp.close()
if__name__=="__main__":
ftp=ftpconnect("113.105.139.xxx","ftp***","Guest***")
downloadfile(ftp,"Faint.mp4","C:/Users/Administrator/Desktop/test.mp4")
#调用本地播放器播放下载的视频
os.system('start"C:.exe""C:/Users/Administrator/Desktop/test.mp4"')
uploadfile(ftp,"C:/Users/Administrator/Desktop/test.mp4","test.mp4")
ftp.quit()
Ⅲ 用python写脚本，从本地上传文件至ftp远程路径的方法，谢谢，
文件ftp用FileZilla For Windows比较好用；
要是托管代码的话，可以使用SVN或者GIt。
Ⅳ python ftp上传文件卡住也没有报错怎么回事
时间过长也就会卡住，但是没有什么报错；这个情况下只能sleep(10)是暂停多少秒，再次上传
Ⅳ python 实现复制粘贴文件后 打包压缩 并连接FTP自动上传到FTP指定目录下
直接用批处理行了
Ⅵ 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。
Ⅶ 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.')
Ⅷ python写的ftp自动上传脚本，怎么判断重复的文件不重传呢size判断不够精确 有没有更好的方式跪求大神
这个没有特别准确的办法。你连SIZE检测也信不过。只有自己改程序了。
办法1：改写FTP程序，加一个hash确认。以前我这么做过。在python里可以轻松做一个FTP SERVER，加上自己做的MD5检测就可以了。
办法2：通过nc转发请求，在NC里设置一个检测。
办法3：如果文件不大，上传完再下载下来检测
办法4：采用自己传有的流水号，重新设置FTP SERVER，让它定期根据流水号，生成检验码，然后你在客户端定期下载这个文件。 这个方法过去在电信系统里经常使用。防出错效果很好。
Ⅸ python ftplib 传输文件大小的文件,如何传输较大文件
没有矛盾啊。只要你不一口气将所有文件都加载到内存里去。使用FTP协议，发送大文件不成问题。
FTP协议是个很简单的协议。你可以仔细看一下原理。然后再配合python的ftplib看。你会发现那些cmd就是FTP的命令。
