我正在尝试通过 pysftp 发送一些文件，身份验证似乎很好，但实际上将文件放入它会导致它挂起，什么也不做。这些文件很小（<200kb），所以我不认为这是一个上传问题（互联网访问很好）。最终连接超时。
代码：
if os.listdir(ftp_path):# only do if files are there
with pysftp.Connection(FTP_SERVER,
port=FTP_PORT
username=FTP_USER,
private_key=FTP_SSH_PRIVATE_KEY_PATH
) as sftp:
with sftp.cd(FTP_REMOTE_FOLDER):
for f in os.listdir(ftp_path):
if os.path.isfile(os.path.join(ftp_path,f)) :
# upload image to server
self.log.info("HB FTP, Start upload: "+f)
print(ftp_path+"\\"+f)
sftp.put(os.path.join(ftp_path,f))
self.log.info("HB FTP, Finished Upload: "+f)
在此处记录输出：
