python基于paramiko将文件上传到服务器代码实现

import paramikoimport datetimeimport oshostname = '服务器ip'username = 'root'password = '服务器密码'port = 22#配置信息可以写到配置文件中#loacl_file是要上传的本地文件路径#remote_path是要上传到服务器上指定文件的路径def upload(local_file, remote_path):  try:    t = paramiko.Transport((hostname, port))    t.connect(username=username, password=password)    sftp = paramiko.SFTPClient.from_transport(t)    print('开始上传文件%s ' % datetime.datetime.now())    try:      sftp.put(local_file, remote_path)    except Exception as e:      sftp.mkdir(os.path.split(remote_path)[0])      sftp.put(local_file, remote_path)      print("从本地： %s 上传到： %s" % (local_file, remote_path))    print('文件上传成功 %s ' % datetime.datetime.now())    t.close()  except Exception as e:    print(repr(e))if __name__ == '__main__':  local_file = r'/home/shl/dataETL/timings/words/word_pos.csv'  remote_path = os.path.join('/home/',"word_pos.csv")  upload(local_file, remote_path)
