Python http requests.exceptions.ConnectionError : ('Connection aborted.' , RemoteDisconnected ('Remote end closed connection without response' ))

Question

我正在编写一个聊天程序。我的每个客户端在一个单独的线程(以及另一个用于发布自己的消息的线程)中都有一个对服务器的开放获取请求。我不想有很多开销。也就是说，客户端不会频繁发送 get 请求来查看是否有任何看不见的消息。相反，它们总是只有一个打开的 get 请求来获取新消息，一旦服务器用新的未见消息响应它们，它们就会立即向服务器发送另一个 get 请求以保持更新等等。
所以在客户端，我有这样的事情:

def coms():
   headers = {'data': myAut.strip()}
   resp = requests.get("http://localhost:8081/receive", headers=headers,timeout=1000000)
   print(resp.text)
   t = threading.Thread(target=coms, args=())
   t.start()

在服务器端，我有这样的事情:

def do_GET(self):

    if self.path == '/receive':
        auth=self.headers['data']
    
    #Using auth, find who has sent this message
        u=None
        for i in range(len(users)):
            print(users[i].aut,auth)
            if users[i].aut==auth:
                u=users[i]
                break


        t=threading.Thread(target=long_Poll,args=(u,self))
        t.start()

和

def long_Poll(client,con):

   while True:

       if len(client.unreadMessages) != 0:
           print("IM GONNA RESPOND")
           con.end_headers()
           con.wfile.write(bytes(client.unreadMessages, "utf8"))
           client.unreadMessages=[]
           break
   con.send_response(200)
   con.end_headers()

而这背后的逻辑是服务器要做长轮询，即保持 GET/receive请求在另一个忙等待线程中打开。当任何客户端通过 POST/message 向服务器发送消息时它只是将此新消息添加到其他客户端 unseenMessages所以一旦他们的线程运行，他们就会从 while True: 中出来循环，服务器向他们提供新消息。换句话说，我想持有客户的 GET/receive打开并且只要我愿意就不会回复它。
这个过程可能需要很长时间。可能是聊天室闲着，很久没有消息了。
现在我遇到的问题是，只要我的客户发送第一个 GET/receive消息，即使我在 GET/receive 中设置了超时值，它也会收到此错误要求这么多。

================================================== ==========================
更新:
奇怪的部分是每当我编辑 GET/receive模块到这个:

 def do_GET(self):
      while True:
         pass

一切正常。
但是当我这样做时:

def do_GET(self):
   t=threading.Thread(target=long_Poll,args=(self))
   t.start()

def long_Poll(con):

  client =None
  while True:
    pass

它给客户端同样的错误!
我的意思是问题是因为我将 self 对象传递给另一个函数来响应？也许它会中断连接？我记得在 Java 套接字编程中遇到过同样的问题，当我想使用套接字在两个函数中进行通信时，有时会遇到一些错误？但是，在这里我只想在长轮询功能中进行交流，而不是其他任何地方。
========================================
更新:
我还将我的服务器和客户端代码放在这里。为简洁起见，我在这里发布了 paste.ubuntu 链接。
客户:
https://paste.ubuntu.com/p/qJmRjYy4Y9/
服务器:
https://paste.ubuntu.com/p/rVyHPs4Rjz/
客户第一次打字时，他输入他的名字，然后他开始发送 GET/receive要求。客户端然后可以通过发送 POST/message 将他的消息发送给其他人。要求。任何时候用户向服务器发送消息，服务器都会找到他(通过他的身份验证)并更新所有其他客户端 unseenMessages这样每当他们的长轮询线程继续时，他们就会收到新消息，他们的客户也会发送另一个 GET/receive立即留言。
