python - 使用 socketserver 处理 http 协议

Question

使用 socketserver 处理 http 协议

我正在构建一个 Web 服务器（...），旨在解释 Python 语言（就像 apache 对 php 所做的那样）。我使用python的socketserver模块通过TCP协议在传输层建立连接（客户端x服务器）。现在我需要捕获请求头数据并向客户端（浏览器）发送一个 http 响应，我该怎么做呢？下面是处理的代码和结果：

文件：httptcpipv4.py

# Module Name : socketserver -> https://docs.python.org/3/library/socketserver.html#module-socketserver
from socketserver import BaseRequestHandler, ThreadingTCPServer


# Transport Layer Protocol : TCP
# This is the superclass of all request handler objects. It defines the interface, given below.
class HTTPTCPIPv4(BaseRequestHandler):
    
    def handle(self):
        
        # self.request is the TCP socket connected to the client
        self.data = self.request.recv(1024).decode()
        print(self.data)


if __name__ == "__main__":
    HOST, PORT = "", 8080

    # Create the asynchronous server, binding to localhost on port 8080
    with ThreadingTCPServer((HOST, PORT), HTTPTCPIPv4) as server:
        print("Server : Action v0.0.1, running address http://127.0.0.1:8080,")
        print("cancel program with Ctrl-C")
        server.serve_forever()

输出 ：
