多线程 上传一个文件到sftp

可以使用paramiko库来实现SFTP文件上传,并且使用Python的多线程实现并发上传。
下面是一个示例代码,其中使用了ThreadPoolExecutor实现并发上传。
```python
import paramiko
import os
from concurrent.futures import ThreadPoolExecutor
class SftpUploader:
def __init__(self, host, port, username, password):
self.host = host
self.port = port
self.username = username
self.password = password
self.transport = None
self.sftp = None
def connect(self):
self.transport = paramiko.Transport((self.host, self.port))
self.transport.connect(username=self.username, password=self.password)
self.sftp = paramiko.SFTPClient.from_transport(self.transport)
def close(self):
if self.sftp:
self.sftp.close()
if self.transport:
self.transport.close()
def upload(self, local_path, remote_path):
self.sftp.put(local_path, remote_path)
print(f'Uploaded {local_path} to {remote_path}')
def upload_file(sftp, local_path, remote_path):
sftp.connect()
sftp.upload(local_path, remote_path)
sftp.close()
if __name__ == '__main__':
sftp = SftpUploader('your_host', 22, 'your_username', 'your_password')
local_folder = '/path/to/local/folder'
remote_folder = '/path/to/remote/folder'
with ThreadPoolExecutor(max_workers=5) as executor:
for file_name in os.listdir(local_folder):
local_path = os.path.join(local_folder, file_name)
remote_path = os.path.join(remote_folder, file_name)
executor.submit(upload_file, sftp, local_path, remote_path)
```
需要注意的是,由于SFTPClient不是线程安全的,因此每个线程需要创建一个SftpUploader对象并连接到SFTP服务器,上传完成后关闭连接。同时,由于SFTP上传速度较慢,可以使用ThreadPoolExecutor控制并发上传的数量。
