我能够成功地将 sftp 与 pysftp 连接起来，但是在下载文件时出现错误，因为FileNotFoundError: [Errno 2] No such file.我还观察到该文件只是在本地路径中添加“？” 连同扩展。以下是更多细节。

在 ftp 中以 Test_03132018080105.csv 的形式文件。在本地路径创建文件为 Test_03132018080105.csv？零字节

代码：

def get_move_on_ftp(ftpsource,localsource):
    if (os.stat(envvar.validfiles).st_size == 0) and (os.stat(envvar.invalidfiles).st_size == 0):
        print("There are no Source files on FTP.")
    else:
        srcinfo={'host':envvar.src_ftphost,'port':envvar.src_ftpport,'username':envvar.src_uname,'password':envvar.src_passwd}
        sftp = pysftp.Connection(**srcinfo)
        sftp.cwd(ftpsource)
        '''  Downloading Files   '''
        avail_files=open(envvar.validfiles,'r')
        for filename in avail_files:
            print(sftp.getcwd())
            #sftp.get(filename, preserve_mtime=True)
            print(filename) # for debug
            sftp.get(filename)
        sftp.close()

错误：

只需在 ftpsource 前面添加“/”即可。即“/2020/Jan/10/”。它应该工作
