pysftp下载失败，因为客户端超出了服务器的内部缓冲区 [英] pysftp download fails because of client exceeded server's internal buffers

问题描述

我只需要从python脚本下载文件，因此代码很简单:

I need just to download a file from a python script, so the code is simple:

import pysftp
sftp = pysftp.Connection('test_host','test',password='test')
sftp.get('testfile', 'c:\\tmp\\testfile3')

下载将开始并以正常速度进行几秒钟，然后停止.没有更多下载，几分钟后服务器关闭了连接. 我要连接的服务器的管理员出于安全原因"不会透露服务器的任何详细信息，但写信给他，他可以看到这样的错误:

The download will start and proceed for a few seconds at normal speed and then stall. Nothing more is downloaded and after a few minutes the connection is closed by the server. The Admin of the server I am connecting to won't disclose any details of the server for 'security reasons', but wrote me that on his end, he can see an error like this:

SFTP错误发送，同时出现太多客户端请求.客户端已超出服务器的内部缓冲区.

SFTP error sending, too many simultaneous client requests. Client has exceeded the server's internal buffers.

我可以从python代码中做些什么吗?

Is there anything I can do about it from the python code?

推荐答案

这是MAX_REQUEST_SIZE问题的另一种体现，在此处的帖子中进行了描述:

This one is another manifestation of the MAX_REQUEST_SIZE problem described in a post here: Paramiko Fails to download large files >1GB

所以我也更改了 sftp_file.py :

MAX_REQUEST_SIZE = 32768

到

MAX_REQUEST_SIZE = 1024

神奇的是，问题似乎已经解决了.

and magically, the problem seems to be solved.
