我的代码如下：
from winrm.protocol import Protocol
p = Protocol(
endpoint='https://windows-host:5986/wsman',
transport='ntlm',
username=r'somedomain\someuser',
password='secret',
server_cert_validation='ignore')
shell_id = p.open_shell()
command_id = p.run_command(shell_id, 'ipconfig', ['/all'])
std_out, std_err, status_code = p.get_command_output(shell_id,
command_id)
p.cleanup_command(shell_id, command_id)
p.close_shell(shell_id)
我想知道什么是ca_trust_path。
