第二个例子

self.download_file(local, filename)
self.ftp.cwd('..')
debug_print('返回上层目录 %s' % self.ftp.pwd())
f.download_files(rootdir_local, rootdir_remote)
'''第二个例子'''区别很大
ftp:
ftp.retrlines('LIST', fuck_callback)
完全是循环，目录的进行循环操作，而文件下载。最底层目录的文件下载完，回归上级目录。继续循环。
self.ftp.pwd()
self.ftp.dir(self.get_file_list)
get_file_list(self, line)
self.ftp.cwd('..')
self.ftp.cwd(remotedir)
self.download_file(local, filename)
建立好本地目录，然后cd到远程目录，下载
