sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 创建UDP Socket: sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) Socket 函数 TCP发送数据时,已建立好TCP链接,所以不需要指定地址,而UDP是面向无连接的,每次发送都需要指定发送给谁。

1、创建和销毁socket socket 模块中的socket(family,type[,proto])函数创建一个新的socket对象。family的取值通常是AF_INET。type 的取值通常是SOCK_STREAM(用于定向的连接,可靠的TCP连接)或SOCK_DGRAM(用于UDP): >>> from socket import * >>> s=socket(AF_INET,SOCK_STREAM) ...
