Python 使用pysftp和paramiko时出现权限错误

我有一个通过sftp传输文件的用例，计划使用python3.7的paramiko或pysftp模块，并且与其中一个目的地/目标有问题。使用winSCP时，文件传输工作正常。任何解决此问题的建议，或实现此目标的具体原因

方法#1：使用paramiko和open#sftp

import paramiko
import os
ssh_client =paramiko.SSHClient()
ssh_client.load_system_host_keys()
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh_client.connect(hostname='abc.com', username='username', password='pwd')
sftp_client=ssh_client.open_sftp()

print(sftp_client.stat(path='/receive/file))
sftp_client.file("createfile","w+")
print(sftp_client.listdir(path='/receive/file'))

import os
import sys
import pysftp
cnopts = pysftp.CnOpts()
cnopts.hostkeys = None
sftp_client = pysftp.Connection(host='abc.com', username='username', password='pwd', cnopts=cnopts,port=22)
print(sftp_client)
sftp_client.chdir ('/receive/file')
print(sftp_client.pwd)
print(sftp_client.listdir())
sftp_client.put('testingfile',preserve_mtime=True)
sftp_client.close()

方法#1-错误
