我正在尝试使用python paramiko代码学习在远程系统上执行命令。 我收到长度为12519个字符的部分输出。 如何获得12550或更长的完整结果？
以下是代码，这是从仅限互联网的其他网站获取的代码
def _run_poll(self, session, timeout, input_data):
'''
Poll until the command completes.
@param session The session.
@param timeout The timeout in seconds.
@param input_data The input data.
@returns the output
'''

maxcount = maxseconds / interval

# because it stalls at 64K bytes (65536).
