在Python子进程中打开SSH连接，避免子进程中出现无限循环

import paramiko

def open_ssh_connection(hostname, username, password):
    # 创建SSH客户端
    client = paramiko.SSHClient()
    # 设置自动添加主机密钥
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    # 连接SSH服务器
    client.connect(hostname, username=username, password=password)
    return client

def execute_command(ssh_client, command):
    # 执行命令
    stdin, stdout, stderr = ssh_client.exec_command(command)
    # 获取命令执行结果
    output = stdout.read().decode()
    return output

# 在子进程中打开SSH连接
if __name__ == '__main__':
    hostname = 'SSH服务器地址'
    username = 'SSH用户名'
    password = 'SSH密码'
    
    ssh_client = open_ssh_connection(hostname, username, password)
    output = execute_command(ssh_client, '远程命令')
    print(output)
    ssh_client.close()
