Python socket 實現程序間通訊
阿新 • • 發佈:2019-02-07
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,一般為AF_UNIX,AF_INET和AF_INET6。AF_UNIX用於同一臺機器上的程序通訊,AF_INET用於IPV4協議的TCP和UDP,AF_INET6用於IPV6協議;
- type代表套接字型別,一般為SOCK_STREAM,SOCK_DGRAM和SOCK_RAW。SOCK_STREAM為流式套接字,用於TCP通訊,SOCK_DGRAM為資料報式套接字,用於UDP通訊,SOCK_RAW為原始套接字,可以用於處理ICMP、IGMP等網路報文,這是普通套接字無法處理的;
- protocal代表協議編號,預設為0。
本地程序間通訊例項
伺服器端:
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()
客戶端:
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()
遠端程序間通訊例項
伺服器端:
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()
客戶端:
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()
