本文实例为大家分享了python实现单线程多任务非阻塞TCP服务端的具体代码,供大家参考,具体内容如下


    # coding:utf-8
    from socket import *

    # 1.创建服务器socket
    sock = socket(AF_INET, SOCK_STREAM)

    # 2.绑定主机和端口
    addr = ('', 7788) #
    sock.bind(addr)

    # 3. 设置最大监听数目,并发
    sock.listen(10)

    # 4. 设置成非阻塞
    sock.setblocking(False)
    # 保存客户端socket
    clientAddrList = []
    # print(sock.)

    while 1:
      try:
        clientSocket, clientAddr = sock.accept()
      except:
        pass
      else:
        print("一个新客户端到来:%s" % str(clientAddr))
        clientSocket.setblocking(False)
        clientAddrList.append((clientSocket, clientAddr))

      for clientSocket, clientAddr in clientAddrList:
        try:
          recvData = clientSocket.recv(1024)
        except:
          pass
        else:
          if len(recvData) > 0:
            print("%s:%s" % (str(clientAddr), recvData))
          else:
            clientSocket.close()
            clientAddrList.remove((clientSocket, clientAddr))
            print("%s 已经下线" % str(clientAddr))

以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
