问python3.6: socket.recv() vs socket.recv_into()性能EN作者 ｜ Raúl Gracia，王钟乐，周煜敏，...
socket.recv_into(buffer[, nbytes[, flags]]) recv_into() 从 socket 中读取nbytes字节的数据写到缓存buffer中,而不是创建一个新的字符串; 参数: buffer—— 接收读取到的数据的缓存, nbytes——打算读取的字节数,如果为0或者没有指定,则会读取 buffer 能容纳的上限个字节; flags同recv() 返回:实际读取的...

4.socket通信的在py3里面,只能发送bytes类型 str-->bytes: bytes(str,"utf-8") bytes-->str:str(bytes"utf-8") 一.基础代码 server端: import socket server = socket.socket() server.bind(("127.0.0.1",6969)) server.listen() con,addr=server.accept() while True: data=con.recv(1024) data_u...
Python Socket API 使用socket.recv(pack_length)接收不定长的数据,如果数据包长度超过一定值,则接收的数据不全,同时还会多触发一次 socket.recv(). 参照python3.4的文档可发现: socket.recv(bufsize[,flags]) Receive data from the socket. The return value is a bytes object representing the data received....

通过socket.socket(family,type,protocol)实现套接字的创建。 1、family:协议簇/地址簇,socket.AF_INET 服务器之间网络通信; 2、Type: socket的类型,socket.SOCK_RAW原始套接字,普通的套接字无法处理ICMP、IGMP等网络报文,而SOCK_RAW可以; 3、protocol:协议类型,IPPROTO_ICMP为1;(socket.getprotobyname(protocolname...
