如何在Python中从多个远程服务器读取多个文件？

import paramiko

def read_remote_files(server_list, file_list):
    for server in server_list:
        try:
            # 创建SSH客户端
            client = paramiko.SSHClient()
            # 自动添加远程主机的SSH密钥
            client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
            # 连接远程服务器
            client.connect(server['host'], username=server['username'], password=server['password'])
            
            for file_path in file_list:
                # 打开远程文件
                sftp = client.open_sftp()
                remote_file = sftp.open(file_path)
                # 读取文件内容
                file_content = remote_file.read()
                print(f"Content of {file_path} on {server['host']}:")
                print(file_content)
                # 关闭文件和SFTP连接
                remote_file.close()
                sftp.close()
            
            # 关闭SSH连接
            client.close()
        except paramiko.AuthenticationException:
            print(f"Authentication failed for {server['host']}")
        except paramiko.SSHException as e:
            print(f"SSH error occurred: {str(e)}")
        except paramiko.sftp.SFTPError as e:
            print(f"SFTP error occurred: {str(e)}")

# 服务器列表
servers = [
    {'host': 'server1.example.com', 'username': 'user1', 'password': 'password1'},
    {'host': 'server2.example.com', 'username': 'user2', 'password': 'password2'}
]

# 文件列表
files = ['/path/to/file1.txt', '/path/to/file2.txt']

# 从多个远程服务器读取多个文件
read_remote_files(servers, files)
