关于#python#的问题，如何解决？

Question

from http.server import HTTPServer, BaseHTTPRequestHandler
from http import HTTPStatus# 导入库


class Handler(BaseHTTPRequestHandler):  # 处理用户请求
    def do_GET(self):  # 修改方法名
        self.send_response(200)  # 告诉用户接通了
        self.send_header("Content_type", 'text/plain;charset=utf-8')
        self.end_header()
        self.wfile.write("hello,zhis:".encode()+self.path[1:].encode())


if __name__ == '__main__':  # 修改变量名
    server_address = ('', 9999)  # 监听端口
    httpd = HTTPServer(server_address, Handler)
    httpd.serve_forever()  # 让程序运行下去

这段代码是搭建一个服务端,然后通过访问http://localhost:9999在网页显示一段文字,课程效果示例截图

但是在我本地运行一直报错

报错内容:

AttributeError: 'Handler' object has no attribute 'end_header'

Answer 1

把self.end_header()改成self.end_headers()
