### 文件夹传输的客户端和服务端实现 以下是基于 Python 和 `tkinter` 的文件夹传输服务端和客户端代码实现。该方案利用了 `socket` 进行通信，并通过递归遍历目录结构来完成整个文件夹的内容传输。 --- #### **服务端代码** ```python import os import socket from pathlib import Path def send_folder(sock, folder_path): """发送指定路径下的所有文件""" sock.sendall(b"FOLDER_START") # 告知客户端即将接收的是一个文件夹 for root, dirs, files in os.walk(folder_path): relative_root = os.path.relpath(root, folder_path) if relative_root == ".": relative_root = "" # 发送当前子目录名 sock.sendall(("DIR:" + relative_root).encode()) sock.recv(1024) # 等待确认 for file_name in files: full_file_path = os.path.join(root, file_name) relative_file_path = os.path.join(relative_root, file_name) with open(full_file_path, "rb") as f: content = f.read() # 发送文件信息 sock.sendall(("FILE:" + relative_file_path + ":" + str(len(content))).encode()) sock.recv(1024) # 等待确认 # 发送文件数据 sock.sendall(content) sock.recv(1024) # 确认接收完毕 sock.sendall(b"FOLDER_END") if __name__ == "__main__": HOST = '127.0.0.1' PORT = 65432 with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s: s.bind((HOST, PORT)) s.listen() print("等待客户端连接...") conn, addr = s.accept() with conn: print(f"Connected by {addr}") folder_to_send = input("请输入要发送的文件夹路径: ") send_folder(conn, folder_to_send) ``` --- #### **客户端代码** ```python import os import socket def receive_folder(sock, base_dir): """接收并保存远程文件夹中的所有内容""" current_state = None while True: data = sock.recv(1024).strip() if not data or data == b"FOLDER_END": break if data.startswith(b"FOLDER_START"): continue elif data.startswith(b"DIR:"): # 处理新目录 dir_name = data.decode()[4:] new_dir = os.path.join(base_dir, dir_name.strip("/\\")) os.makedirs(new_dir, exist_ok=True) sock.sendall(b"DONE") elif data.startswith(b"FILE:"): # 处理文件 parts = data.decode()[5:].split(":") file_name = parts[0] file_size = int(parts[1]) file_path = os.path.join(base_dir, file_name) remaining_bytes = file_size with open(file_path, "wb") as f: while remaining_bytes > 0: chunk = sock.recv(min(remaining_bytes, 1024)) f.write(chunk) remaining_bytes -= len(chunk) sock.sendall(b"DONE") if __name__ == "__main__": HOST = '127.0.0.1' PORT = 65432 with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s: s.connect((HOST, PORT)) save_location = input("请输入保存文件夹的位置: ") os.makedirs(save_location, exist_ok=True) receive_folder(s, save_location) ``` --- #### **GUI 部分 (Tkinter)** 为了使用户能够更直观地选择文件夹，可以通过 `tkinter` 添加图形化界面支持： ##### **服务端 GUI** ```python import tkinter as tk from tkinter import filedialog def start_server(): folder_selected = folder_var.get() if not folder_selected: status_label.config(text="请选择文件夹！", fg="red") return try: # 启动服务端逻辑... status_label.config(text=f"正在发送文件夹：{folder_selected}", fg="green") except Exception as e: status_label.config(text=str(e), fg="red") root = tk.Tk() root.title("文件夹传输 - 服务端") frame = tk.Frame(root) frame.pack(padx=10, pady=10) tk.Label(frame, text="选择文件夹").grid(row=0, column=0, sticky=tk.W) folder_var = tk.StringVar() entry = tk.Entry(frame, textvariable=folder_var, width=50) entry.grid(row=0, column=1) browse_button = tk.Button( frame, text="浏览", command=lambda: folder_var.set(filedialog.askdirectory()), ) browse_button.grid(row=0, column=2) start_button = tk.Button(frame, text="启动服务", command=start_server) start_button.grid(row=1, columnspan=3, pady=(10, 0)) status_label = tk.Label(frame, text="", fg="black") status_label.grid(row=2, columnspan=3, pady=(10, 0)) root.mainloop() ``` ##### **客户端 GUI** ```python import tkinter as tk from tkinter import filedialog def start_client(): location_selected = location_var.get() if not location_selected: status_label.config(text="请选择保存位置！", fg="red") return try: # 启动客户端逻辑... status_label.config(text=f"正在接收文件到：{location_selected}", fg="green") except Exception as e: status_label.config(text=str(e), fg="red") root = tk.Tk() root.title("文件夹传输 - 客户端") frame = tk.Frame(root) frame.pack(padx=10, pady=10) tk.Label(frame, text="选择保存位置").grid(row=0, column=0, sticky=tk.W) location_var = tk.StringVar() entry = tk.Entry(frame, textvariable=location_var, width=50) entry.grid(row=0, column=1) browse_button = tk.Button( frame, text="浏览", command=lambda: location_var.set(filedialog.askdirectory()), ) browse_button.grid(row=0, column=2) start_button = tk.Button(frame, text="开始接收", command=start_client) start_button.grid(row=1, columnspan=3, pady=(10, 0)) status_label = tk.Label(frame, text="", fg="black") status_label.grid(row=2, columnspan=3, pady=(10, 0)) root.mainloop() ``` --- ### 功能说明 - 使用 `os.walk()` 方法递归获取文件夹内的所有文件及其相对路径。 - 利用自定义协议 (`FOLDER_START`, `FOLDER_END`, `DIR:`, `FILE:`)，确保双方能正确解析文件夹结构。 - 提供简单的 GUI 支持，便于用户交互[^1]。 --- ### 注意事项 - 确保服务端和客户端在同一局域网下运行，或者开放防火墙允许外部访问。 - 如果需要跨平台部署，可使用 PyInstaller 打包脚本为独立执行文件[^3]。 ---
