ftp 下载文件异常，只可以下载文件名字
def download_file(self, localfile, remotefile):

if file_arr[1] not in ['.', '..']:
self.file_list.append(file_arr)

def get_filename(self, line):

while(line[pos] != ' '):
pos += 1
while(line[pos] == ' '):
pos += 1
file_arr = [line[0],line[pos:]]
return file_arr


异常出现在 def download_file 中。
