Python socket 实现进程间通

Python socket 使用方法如下

socket = socket.socket(family, type[, protocal])

• family代表地址家族，一般为AF_UNIX，AF_INET和AF_INET6。AF_UNIX用于同一台机器上的进程通信，AF_INET用于IPV4协议的TCP和UDP，AF_INET6用于IPV6协议；
• type代表套接字类型，一般为SOCK_STREAM，SOCK_DGRAM和SOCK_RAW。SOCK_STREAM为流式套接字，用于TCP通信，SOCK_DGRAM为数据报式套接字，用于UDP通信，SOCK_RAW为原始套接字，可以用于处理ICMP、IGMP等网络报文，这是普通套接字无法处理的;
• protocal代表协议编号，默认为0。

服务器端：

import socket
import os

if __name__ == '__main__':
    server = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
    if os.path.exists("/tmp/test.sock"):
        os.unlink("/tmp/test.sock")
    server.bind("/tmp/test.sock")
    server.listen(0)
    while True:
        connection, address = server.accept()
        connection.send("test: %s"% connection.recv(1024))
    connection.close()

客户端：

import socket
import os

if __name__ == '__main__':
    client = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
    client.connect("/tmp/test.sock")

    instr = raw_input()
    client.send(instr)
    print client.recv(1024)

    client.close()

服务器端：

import socket
import os

if __name__ == '__main__':
    server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server.bind(("localhost", 8888))
    server.listen(0)
    while True:
        connection, address = server.accept()
        connection.send("test: %s"% connection.recv(1024))
    connection.close()

客户端：

import socket
import os

if __name__ == '__main__':
    client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    client.connect(("localhost", 8888))

    instr = raw_input()
    client.send(instr)
    print client.recv(1024)

    client.close()
