我需要在 python 上的 POST 网络服务器中修复什么？

Question

我有一个脚本来获取 json 并在我的 ubuntu 服务器上使用白色 IP 运行它 我接受json，但不完全接受，接受后，脚本关闭连接并且不起作用 我认为问题是我错误地接收了数据包，但是由于我的经验很少，我不清楚为什么它不接受第二个数据包以及为什么它会在无限循环中关闭

import os
import socket
from pathlib import Path
from dotenv import load_dotenv
import json


#Init .env
env_path = Path('.') / '.env'
load_dotenv(dotenv_path=env_path)
#create webserver socket
def start_my_server():
    socket_server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    socket_server.bind(('ip', port))
    socket_server.listen(32768)
    print('Working...')
    global data
    global HDRS
    while True:
        client_socket, address = socket_server.accept()
        data = client_socket.recv(32768).decode('utf-8')
        # content = 'Well done'.encode('utf-8')
        HDRS = 'HTTP/1.1 200 OK\r\nContent-Type: text/html; charset=utf-8\r\n\r\n'
        # content = load_page_from_get_request(data)
        client_socket.send(HDRS.encode('utf-8'))
        # a = client_socket.send(HDRS.encode('utf-8'))
        # print(a, '+'*20)
        client_socket.shutdown(socket.SHUT_WR)
        load_page_from_get_request(32768)
    # print('end')
    # socket_server.close()

def load_page_from_get_request(request_data):
    HDRS = 'HTTP/1.1 200 OK\r\nContent-Type: text/html; charset=utf-8\r\n\r\n'
    HDRS_404 = 'HTTP/1.1 404 OK\r\nContent-Type: text/html; charset=utf-8\r\n\r\n'
    try:
        with open('data.json', 'w') as output_file:
            json.dump(data, output_file)
        return HDRS.encode('utf-8')
    except EOFError:
        return HDRS_404.encode('utf-8')
    # try

if __name__ == '__main__':
    start_my_server()
