我有以下代码要从4个不同的FTP服务器下载。它在我的本地机器上工作，但在服务器上"；ftp4"；未连接。奇怪的是，我可以连接到"；ftp4"；使用FileZilla在服务器上没有任何问题。这是代码：
HOST_LIST = [["10.10.10.04", "user", "pasword"]] #ftp4
self.cnopts = pysftp.CnOpts()
self.cnopts.hostkeys = None
def get_r_portable(self, sftp, remotedir, localdir, preserve_mtime=False):
for entry in sftp.listdir(remotedir):
remotepath = remotedir + "/" + entry
localpath = os.path.join(localdir, entry)
mode = sftp.stat(remotepath).st_mode
if S_ISREG(mode):
if self.PATHFILTER.strip() != "":
if str(remotepath).lower().find(self.PATHFILTER.lower()) > -1:
sftp.get(remotepath, localpath, preserve_mtime=preserve_mtime)
for host in self.HOST_LIST:
with pysftp.Connection(host[0], username=host[1], password=host[2], cnopts=self.cnopts) as sftp:
try:
for dirs in self.FOL_LIST:
currdir = REMOTEFOLDER + dirs + ""
try:
self.get_r_portable(sftp, currdir, self.LOCALFOLDER, True)
except Exception as e:
self.logger.error("Exception in dir exploration" + str(e))
except Exception as e:
print('error')
我得到的错误是"；ftp4"：

您正在连接FileZilla中的FTP服务器。
pysftp是SFTP库。
FTP和SFTP是完全不同的协议。
要在Python中连接FTP，请使用ftplib。
如果您试图连接到错误的端口，也可能发生此错误。
默认情况下，pysftp使用端口22(标准SFTP端口(，但有些主机使用不同的端口。
例如，Namecheap使用端口21098进行SFTP连接。为此，您可以在对pysft的调用中包含port参数。连接：
pysftp.Connection(host, username=myusername, password=mypassword, port=21098, cnopts=mycnopts)
