Question

（我有以下代码，它们想要实现服务器端应用程序并向客户端发送响应：

>#r "C:\Users\...\Project.dll"
>using System;
>using System.Reflection;
>Assembly assembly = >Assembly.LoadFrom("C:\Users\...\Project.dll");
> Object mc = assembly.CreateInstance("AccessInternal.MyClass");
> Type t = mc.GetType();
> BindingFlags bf = BindingFlags.Instance | BindingFlags.NonPublic;
> MethodInfo mi = t.GetMethod("MyMethod", bf);
> string result = (string)mi.Invoke(mc, null);
> Console.WriteLine(result);
Hello world!
>

现在我写一个简单的客户端：

class client(Thread):
  def __init__(self, socket, address):
     Thread.__init__(self)
     self.sock = socket
     self.addr = address
     self.start()

def run(self):
    request=''
    while 1:
      data=self.sock.recv(1024).decode() #the program hangs here with large message
      if not data:
         break
      request+=data
   print(request, self.addr[1], self.addr[0]))
   message = "test"
   self.sock.send(message.encode())


def init_server():
  serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  serversocket.bind((host, int(port)))
  serversocket.listen(5)     
  while 1:
      clients, address = serversocket.accept()
      client(clients, address)
  return

现在的问题是服务器挂在具有大消息的recv中。该怎么解决？

您的客户端套接字和服务器套接字是不同的套接字。

您可以使用serversocket对象来获取服务器信息，就像尝试self.sock

一样。

我建议将serversocket作为第三个参数解析到您的client类中，然后像这样在类中使用它

class client(Thread):
  def __init__(self, socket, address, server):
     Thread.__init__(self)
     self.sock = socket
     self.addr = address
     self.server = server
     self.start()

def run(self):
    request=''
    while 1:
      data=self.sock.recv(1024).decode()
      if not data:
         break
      request+=data
   print(request, self.server.getsockname()[1], self.server.getsockname()[0]))

def init_server():
  serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  serversocket.bind((host, int(port)))
  serversocket.listen(5)     
  while 1:
      clients, address = serversocket.accept()
      client(clients, address, serversocket)
  return

这应该输出服务器信息

如果您需要客户端信息，则将其作为元组解析在“地址”中，您可以看到用于进行通信的远程IP和套接字端口（不是开放端口）

Python套接字利用客户端地址和端口进行响应
