二、主要特性
1、 支持多线程、多连接的文件传输。
示例代码:
class MultiThreadFTPTransfer: def __init__(self, num_threads, host, port, username, password, local_file_path, remote_file_path): self.num_threads = num_threads self.host = host self.port = port self.username = username self.password = password self.local_file_path = local_file_path self.remote_file_path = remote_file_path self.file_size = os.path.getsize(local_file_path) self.block_size = self.file_size // num_threads def download(self): threads = [] for i in range(self.num_threads): start_pos = i * self.block_size end_pos = (i + 1) * self.block_size - 1 thread = Thread(target=self._download_block, args=(i + 1, start_pos, end_pos)) thread.start() threads.append(thread) for thread in threads: thread.join() def _download_block(self, block_num, start_pos, end_pos): ftp = FTP(host=self.host, user=self.username, passwd=self.password) ftp.login() ftp.cwd(os.path.dirname(self.remote_file_path)) ftp.sendcmd('TYPE I') ftp.sendcmd('REST {}'.format(start_pos)) buffer_size = 1024 * 1024 * 10 buf = BytesIO() ftp.retrbinary('RETR %s' % os.path.basename(self.remote_file_path), buf.write, buffer_size, end_pos - start_pos + 1) with open('{}.block{}'.format(self.local_file_path, block_num), 'wb') as f: f.write(buf.getvalue()) ftp.quit() os._exit(0)
2、 提供丰富的界面配置选项。
示例代码:
class XFTPMAC(QWidget): def __init__(self): super(XFTPMAC, self).__init__() self.initUI() def initUI(self): # set window title, icon, and size self.setWindowTitle('XFTPMAC') self.setWindowIcon(QIcon('icon.png')) self.resize(800, 600) # create widgets toolbar = QToolBar() toolbar.addAction(QAction('Connect', self)) toolbar.addAction(QAction('Upload', self)) toolbar.addAction(QAction('Download', self)) treeview = QTreeView() model = QFileSystemModel() model.setRootPath('') treeview.setModel(model) treeview.setRootIndex(model.index(os.path.expanduser("~"))) tabwidget = QTabWidget() tabwidget.addTab(QLabel('Tab 1'), 'Tab 1') tabwidget.addTab(QTextEdit(), 'Tab 2') statusbar = QStatusBar() statusbar.showMessage('Ready') # create layout vbox = QVBoxLayout() vbox.addWidget(toolbar) vbox.addWidget(treeview) vbox.addWidget(tabwidget) vbox.addWidget(statusbar) # set main window layout self.setLayout(vbox) self.show()
三、应用案例
1、 用于网站搭建。
示例代码:
ftp = ftplib.FTP() ftp.connect('ftp.example.com', 21) ftp.login(user='username', passwd='password') ftp.cwd('path/to/remote/directory') with open('path/to/local/file', 'rb') as f: ftp.storbinary('STOR filename', f) ftp.quit()
2、 用于文件备份。
示例代码:
import paramiko ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect('ssh.example.com', username='username', password='password') sftp = ssh.open_sftp() sftp.put('path/to/local/file', 'path/to/remote/file') sftp.close() ssh.close()
3、 用于数据导入导出。
示例代码:
import pandas as pd ftp = ftplib.FTP() ftp.connect('ftp.example.com', 21) ftp.login(user='username', passwd='password') ftp.cwd('path/to/remote/directory') with ftp.open('filename.csv', 'wb') as f: df = pd.read_sql_query('SELECT * FROM table', con) df.to_csv(f, index=False) ftp.quit()
四、总结
综上所述,XFTPMAC是一个功能强大的文件传输工具,提供了多种连接协议和高级功能,适用于各种文件传输场景。如果你需要进行文件上传、下载、备份、导出等操作,XFTPMAC绝对是一个不错的选择。
