无法使用python套接字编程下载文件

import socket

def download_file(server_ip, server_port, file_path):
    # 创建套接字
    client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    
    try:
        # 连接服务器
        client_socket.connect((server_ip, server_port))
        
        # 发送下载请求
        request = f"GET {file_path} HTTP/1.1\r\nHost: {server_ip}\r\n\r\n"
        client_socket.send(request.encode())
        
        # 接收响应
        response = client_socket.recv(4096)
        
        # 解析响应头
        headers, content = response.split(b'\r\n\r\n', 1)
        status_code = headers.split(b' ')[1]
        
        if status_code == b'200':  # 下载成功
            # 提取文件名
            file_name = file_path.split('/')[-1]
            
            # 写入文件
            with open(file_name, 'wb') as file:
                file.write(content)
            
            print(f"文件下载成功，保存为 {file_name}")
        else:
            print("文件下载失败")
    finally:
        # 关闭套接字
        client_socket.close()

# 示例用法
download_file('server_ip', 80, '/path/to/file.txt')
