写一个基于TCP协议套接字，服务端实现接收客户端的连接并发。

1. 基于多线程实现

   # server.py
   import socket
   from threading import Thread
   
   def task(server):
       while True:
           try:
               data = server.recv(1024).decode('utf-8')
               print(data)
   
               server.send(data.encode('utf-8'))
           except Exception:
               break
       conn.close()
   
   server = socket.socket()
   server.bind(('127.0.0.1',9999))
   server.listen()
   
   while True:
       conn ,addr = server.accept()
       t = Thread(target=task, args=(conn,))
       t.start()

   # client.py
   import socket
   
   client = socket.socket()
   
   client.connect(('127.0.0.1',9999))
   
   while True:
       msg = input('请输入')
       client.send(msg.encode('utf-8'))
   
       data = client.recv(1024).decode('utf-8')
       print(data)
   

2. 基于多进程实现

   # server.py
   import socket
   from multiprocessing import Process
   
   def task(conn):
   
       while True:
           try:
               data = conn.recv(1024).decode('utf-8')
               print(data)
   
               conn.send(data.encode('utf-8'))
           except Exception:
               break
       conn.close()
   
   if __name__ == '__main__':
       server = socket.socket()
       server.bind(('127.0.0.1', 9999))
       server.listen()
       while True:
           conn, addr = server.accept()
   
           t = Process(target=task,args=(conn,))
           t.start()
   

   # client.py
   import socket
   
   client = socket.socket()
   
   client.connect(('127.0.0.1',9999))
   
   while True:
       msg = input('请输入')
       client.send(msg.encode('utf-8'))
   
       data = client.recv(1024).decode('utf-8')
       print(data)

3. 单线程内多协程实现并发

   # server.py
   from gevent import monkey;monkey.patch_all()
   import gevent
   import socket
   
   def talk(conn):
       try:
           while True:
               data = conn.recv(1024).decode('utf-8')
               print(data)
               conn.send(data.encode('utf-8'))
       except Exception:
           pass
       conn.close()
   
   server = socket.socket()
   server.bind(('127.0.0.1', 9999))
   server.listen()
   while True:
       conn, addr = server.accept()
       gevent.spawn(talk, conn)

   # client.py
   import socket
   
   client = socket.socket()
   
   client.connect(('127.0.0.1',9999))
   
   while True:
       msg = input('请输入')
       client.send(msg.encode('utf-8'))
   
       data = client.recv(1024).decode('utf-8')
       print(data)
