如何使用Python BaseHTTPServerRequestHandler do_GET方法提供图像内容类型？

from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer
import os

class MyHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        try:
            # 设置响应状态码为200
            self.send_response(200)
            
            # 设置响应头部
            self.send_header('Content-type', 'image/jpeg')
            self.end_headers()
            
            # 读取图像文件
            with open('image.jpg', 'rb') as f:
                image_data = f.read()
            
            # 发送图像数据作为响应内容
            self.wfile.write(image_data)
        
        except IOError:
            # 发生IO错误时，返回404错误
            self.send_error(404, 'File Not Found')

def run():
    try:
        # 创建HTTP服务器，并指定处理请求的处理程序
        server = HTTPServer(('', 8000), MyHandler)
        print('Started HTTP server on port 8000')
        
        # 启动服务器，一直运行直到按下Ctrl+C
        server.serve_forever()
    
    except KeyboardInterrupt:
        print('^C received, shutting down the server')
        server.socket.close()

if __name__ == '__main__':
    run()
