关键词查询的分析网站有网打不开网页咋回事

局域网传输文件是最最常用的功能，我参考https://www.jb51.net/python/345837qrz.htm这篇文章，复制粘贴，开发了一个。但发现进度条没有用，也没有显示传输用时和传输速度的功能，于是我改写了代码，使它实现这个功能。

import socket
import osdef start_server(host='192.168.1.145', port=8888):server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)server_socket.bind((host, port))server_socket.listen(1)print(f"服务器启动，监听 {host}:{port}")while True:client_socket, addr = server_socket.accept()print(f"连接来自 {addr}")# 接收文件名和大小file_info = client_socket.recv(1024).decode()file_name, file_size = file_info.split('|')file_size = int(file_size)# 创建文件并写入数据with open('d:/socketfile/'+file_name, 'wb') as file:received = 0while received < file_size:data = client_socket.recv(4096)file.write(data)received += len(data)print(f"接收进度: {received}/{file_size} 字节")client_socket.close()print(f"文件 {file_name} 接收完成")if __name__ == "__main__":start_server()

上面是服务器端，没有怎么改，增加了'd:/socketfile/'+file_name，把文件放在我们想要放的文件夹。

以上就改动比较大，也让我慢慢熟悉面向对象编程，用self.可以为公用变量，增加时间和速度的显示，原来代码出现tk.Progressbar报错，进度条无法正常显示等问题。

速度还是可以的。

用一段时间，感觉还是不爽，要开2个程序，一个是服务器端，一个是客户端，才能在2台电脑中互传文件，为此，我把它一体化，只要用一个程序就实现了服务器端和客户端的功能，又能接受文件，又能发送文件。同时，加上我一直喜欢用的拖放功能，不能每次去选择文件传输。

填好ip，点击启动服务器就可以接收文件。下面还能显示接收到的文件。
