Python socket 实现进程间通

发布时间:2019-09-26 12:29:09编辑:auto阅读(2125)

    基本用法

    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。

    本地进程间通信实例

    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()
    

    远程进程间通信实例

    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()
