如何从python发送正确的http响应？

import http.server
import http.client

class MyHandler(http.server.BaseHTTPRequestHandler):
    def do_GET(self):
        self.send_response(200)  # 设置响应状态码
        self.send_header('Content-type', 'text/html')  # 设置响应头
        self.end_headers()
        self.wfile.write(b"Hello, World!")  # 发送响应内容

if __name__ == '__main__':
    server_address = ('', 8000)
    httpd = http.server.HTTPServer(server_address, MyHandler)
    httpd.serve_forever()

import http.client

conn = http.client.HTTPSConnection("www.example.com")
conn.request("GET", "/")
response = conn.getresponse()

print(response.status)  # 打印响应状态码
print(response.read())  # 打印响应内容
