#login(user='anonymous',passwd='', acct='') 登录到FTP服务器,所有的参数都是可选的
#pwd() 得到当前工作目录
#cwd(path) 把当前工作目录设置为path
#dir([path[,...[,cb]]) 显示path目录里的内容,可选的参数cb 是一个回调函数,它会被传给retrlines()方法
#nlst([path[,...]) 与dir()类似,但返回一个文件名的列表,而不是显示这些文件名
#retrlines(cmd [, cb]) 给定FTP 命令(如“RETR filename”),用于下载文本文件。可选的回调函数cb 用于处理文件的每一行
#retrbinary(cmd, cb[,bs=8192[, ra]]) 与retrlines()类似,只是这个指令处理二进制文件。回调函数cb 用于处理每一块(块大小默认为8K)下载的数据。
#storlines(cmd, f) 给定FTP 命令(如“STOR filename”),以上传文本文件。要给定一个文件对象f
#storbinary(cmd, f[,bs=8192]) 与storlines()类似,只是这个指令处理二进制文件。要给定一个文件对象f,上传块大小bs 默认为8Kbs=8192])
#rename(old, new) 把远程文件old 改名为new
#delete(path) 删除位于path 的远程文件
#mkd(directory) 创建远程目录
#每个需要输入的地方,需要进行排查检错。仅仅这个功能太小了。不过根据实际情况更改,放在bt里边当个小工具即可
#有点烂,没有做任何try
