I need to simulate a UDP server, which sends content of a text file line by line in an endless loop. I have written the code below but at the other end I do not receive anything (The other side is Qt code and I am sure it works): ...
s.sendto(string[,flag],address) 发送UDP 数据。将数据发送到套接字,address 是形式为(ipaddr,port)的元组,指定远程地址。返回值是发送的字节数。 s.close() 关闭套接字。 流式套接字 当你需要使用 TCP 协议进行通信时,需要创建流式套接字。这是套接字编程中最常用的一种。
UDP是一种无连接协议,服务器无需预先建立连接就可以直接发送和接收数据报文。这意味着效率更高,但同时也失去了TCP提供的诸如流量控制、拥塞控制和错误校验等功能。 2.3.2 实现UDP服务器与客户端通信 2.3.2.1 数据报的发送与接收 在UDP服务器端,我们不需要调用listen()和accept(),而是直接recvfrom()和sendto():...
