求等价于python -m http.server的可配置Python GET请求服务器类

你需要的是基于Python标准库的实现，直接复用官方http.server模块里的SimpleHTTPRequestHandler即可——它就是python -m http.server命令背后的核心处理类，已经完整实现了GET请求的静态文件服务逻辑（包括目录列表、文件读取与返回等）。

以下是支持配置地址、端口和目录的完整代码：

from http.server import HTTPServer, SimpleHTTPRequestHandler
import argparse
import os

def main():
    parser = argparse.ArgumentParser(description='Simple HTTP static file server')
    parser.add_argument('--bind', '-b', default='', help='Bind address (default: all interfaces)')
    parser.add_argument('--port', '-p', type=int, default=8000, help='Service port (default: 8000)')
    parser.add_argument('--directory', '-d', default=os.getcwd(), help='Root directory for file serving (default: current working directory)')
    args = parser.parse_args()

    # 切换到指定目录，SimpleHTTPRequestHandler会以此为根目录提供服务
    os.chdir(args.directory)
    
    server_address = (args.bind, args.port)
    httpd = HTTPServer(server_address, SimpleHTTPRequestHandler)
    
    print(f"Serving HTTP on {args.bind or '0.0.0.0'} port {args.port} (http://{args.bind or 'localhost'}:{args.port}/) ...")
    try:
        httpd.serve_forever()
    except KeyboardInterrupt:
        print("\nKeyboard interrupt received, shutting down server.")
        httpd.server_close()

if __name__ == '__main__':
    main()

说明 #

• 运行方式和官方命令行工具完全一致，例如：

  python your_server_script.py --bind 127.0.0.1 --port 9000 --directory /home/user/docs
  

• 如果不需要命令行参数，直接硬编码配置的话，可以简化成：

  from http.server import HTTPServer, SimpleHTTPRequestHandler
  import os
  
  # 直接配置参数
  BIND_ADDR = '127.0.0.1'
  PORT = 9000
  SERV_DIR = '/home/user/docs'
  
  os.chdir(SERV_DIR)
  httpd = HTTPServer((BIND_ADDR, PORT), SimpleHTTPRequestHandler)
  print(f"Serving HTTP on {BIND_ADDR} port {PORT} ...")
  try:
      httpd.serve_forever()
  except KeyboardInterrupt:
      httpd.server_close()
