学习python后写的关于网络编程,线程的例子
该例子综合了python的网络编程,线程,异常处理,字符串处理,函数,类,做为入门级的例子,很实用
服务器端server.py
#coding=utf-8
import socket
import threading
from time import sleep
class ThreadClass(threading.Thread):
def setClient(self,client):
self.client = client
def run(self):
print('threadname-->',self.getName())
s = self.client.recv(1024).decode('utf-8')
try:
s = eval(s)
s = str(s)
except NameError:
pass
s = 'server deal result:' + s + "\n"
self.client.send(s.encode('utf-8'))
self.client.close()
if __name__=='__main__':
s = socket.socket()
host = socket.gethostname()
port = 1234
s.bind((host,port))
#最多同时连5个客户端
s.listen(5)
while True :
client,addr = s.accept()
threadclass = ThreadClass()
threadclass.setClient(client)
threadclass.start()
#sleep(20)
#if threadclass.isAlive():
#print('alive')
#else:
#print("notAlive")
客户端client.py
#coding=utf-8
import socket
def sendSource(source):
return source.encode('utf-8')
def recvSource(source):
return source.decode('utf-8')
def dealSource(source):
try:
s = socket.socket()
s.connect(('10.9.9.12',1234))
s.send(sendSource(source))
#缓冲区1k
print(recvSource(s.recv(1024)))
except socket.timeout:
print("timeout")
finally:
s.close()
if __name__=='__main__':
while True:
source = input("input your source:\n")
if str.strip(source)=="quit":#退出
quit()
else:#交给服务器处理
dealSource(source)
几点需要注意:
1.代码里有中文的话要指定#coding=utf-8
2.命令行输入的数据要去空格str.strip(source)
