Python Socket Server
今天做ftp的界面,做的相当郁闷，弄得心情及其不爽，在网上搜到死都不知道该怎么办，打算明天先看看C＋＋
的是怎么弄的再说。不过，现在我想写一下关于socket的编程。
先写一个时间服务器吧，他监听端口，并且会返回 服务器的时间
server.py
#!/usr/bin/python
# Copyright (c) angelipin (angelipin@126.com)
import SocketServer
import time
import logging
__version__ = "1.0.0"
class ServerHandler(SocketServer.BaseRequestHandler):
def setup(self):
logging.info("start thread.")
self.request.settimeout(60)
def finish(self):
self.request.close()
logging.info("end thread.")
def handle(self):
while 1:
try:
dataReceived = self.request.recv(1024)
if not dataReceived:
break
logging.info('Receive data '+dataReceived)
dataSend = time.ctime(time.time())
self.request.send(dataSend)
except socket.timeout:
print "Time out"
logging.error("Time out")
logging.basicConfig(level=logging.DEBUG,format='%(thread)d %(asctime)s %(levelname)s %(message)s',filename='log',filemode='a+')
Server = SocketServer.ThreadingTCPServer(('',8881),ServerHandler)
logging.info('Server start')
Server.serve_forever()
用来做测试用的client.py
import socket
remote_host = '127.0.0.1'
remote_port = 8881
send_buf = open('binary','rb').read()
sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
sock.connect((remote_host,remote_port))
sock.send(send_buf)
response_data = sock.recv(1024)
print response_data
sock.close()
随便在binary文件里面写点东西 或者 你直接换成。。。对吧
测试 先启动 server
然后运行几个client看看
while true;
do
python client.py;
done;
你也可以写个多线程的测试。像我这样的就是多开几个shell都运行上面的代码。唉，怎么结束呢？

A Byte Of Python
中关于继承有这样的文字：
Suppose you want to write a program which has to keep track of the
teachers and students in a college. They have some common

说实话，Python真的不太适合做这种二进制的东西，天生没有指针，导致在C/C++很容易的东西在Python下就很麻烦。不过好像3.1有了原生的bytes类型，不知道能不能改变现状。

偶尔做个简单的WEB服务测试程序，我还是喜欢采用PHP。简洁，风格和C/C++接近，上手快，而且库也很齐全。以前为广东移动做移动行业终端的演示程序时，采用国内一个兄弟写的FleaPHP开源框架，两周不到的时间，我从一个对PHP一无所知的水平，快速的搞定了30多个页面的后台，后来演示效果也不错，也很稳定，从此对PHP有� ......
