python socketserver安装 socket.socket python,本文用python进行socket编程,实现客户端和服务器互相发送字符串,并在标准输出打印。TCP协议版本下面是客户端程序:importsocketsock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)server_address=('192.168.33.5',666
AF_UNIX, AF_LOCAL:用于本地通信,Unix Domain Socket AF_INET:IPv4协议栈 AF_INET6:IPv6协议栈 还有其他一些参看官方文档 type参数定义通信语义 SOCK_STREAM:提供一种有序的,可靠的,双向的,基于连接的字节流 SOCK_DGRAM:支持数据报文(非连接的,不可靠的具有固定的最大字节长度的消息) ...
