基于Python實(shí)現(xiàn)局域網(wǎng)內(nèi)Windows桌面文件傳輸

更新時間：2025年11月23日 14:12:52 作者：燕鵬01

這篇文章介紹了如何使用Python實(shí)現(xiàn)一個局域網(wǎng)文件傳輸系統(tǒng),包括發(fā)送端和接收端的代碼示例,發(fā)送端和接收端都需要在同一局域網(wǎng)內(nèi)運(yùn)行,并且確保防火墻允許通信,圖形界面版本需要安裝tkinter庫,需要的朋友可以參考下

發(fā)送端代碼 (sender.py)

import socket
import os
import tqdm
import argparse

def send_file(host, port, file_path):
    """

    filename = os.path.basename(file_path)
    
    # 創(chuàng)建socket對象
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    
    print(f"[+] 正在連接到 {host}:{port}")
    s.connect((host, port))
    print("[+] 連接成功")
    
    # 發(fā)送文件名和文件大小
    file_info = f"{filename}|{file_size}"
    s.send(file_info.encode())
    
    # 等待確認(rèn)
    response = s.recv(1024).decode()
    if response != "READY":
        print("[-] 接收端未準(zhǔn)備就緒")

使用說明

命令行版本

安裝依賴：

pip install tqdm

在接收端運(yùn)行：

python receiver.py -H 0.0.0.0 -p 8888 -d received_files

在發(fā)送端運(yùn)行：

python sender.py 192.168.1.100 file.txt -p 8888

圖形界面版本

安裝依賴：

pip install tqdm

運(yùn)行圖形界面：

python file_transfer_gui.py

注意事項(xiàng)

確保發(fā)送端和接收端在同一個局域網(wǎng)內(nèi)
確保防火墻允許程序通過指定端口通信
大文件傳輸可能需要較長時間
圖形界面版本需要安裝tkinter（通常Python自帶）

這個實(shí)現(xiàn)提供了基本的文件傳輸功能，可以根據(jù)需要進(jìn)行擴(kuò)展，比如添加加密、壓縮、斷點(diǎn)續(xù)傳等功能。

到此這篇關(guān)于基于Python實(shí)現(xiàn)局域網(wǎng)內(nèi)Windows桌面文件傳輸?shù)奈恼戮徒榻B到這了,更多相關(guān)Python Windows文件傳輸內(nèi)容請搜索腳本之家以前的文章或繼續(xù)瀏覽下面的相關(guān)文章希望大家以后多多支持腳本之家！
