从网上参考了一些代码，实现了一个Python实现的基于线程的socket server, 用来实现各种服务系统的原型。放在这里供以后参考。
#!/usr/bin/env python
import threading
import SocketServer
users = []
class MyTCPHandler(SocketServer.StreamRequestHandler):
def handle(self):
username = None
while True:
self.data = self.rfile.readline().strip()
cur_thread = threading.currentThread()
print "RECV from ", self.client_address[0]
cmd = self.data
if cmd == None or len(cmd) == 0:
break;
print cmd
# business logic here
try:
if cmd.startswith('echo'):
result = cmd[5:]
elif cmd.startswith('login'):
username = cmd[6:]
users.append({username:self.wfile})
result = username + ' logined.'
elif cmd == 'quit':
break
else:
result = 'error cmd'
self.wfile.write(result)
self.wfile.write('\n')
except:
print 'error'
break
try:
if username != None:
users.remove(username)
except:
pass
print username, ' closed.'
class ThreadedTCPServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer):
pass
if __name__ == "__main__":
HOST, PORT = "localhost", 9999
server = ThreadedTCPServer((HOST, PORT), MyTCPHandler)
server_thread = threading.Thread(target=server.serve_forever)
server_thread.setDaemon(True)
server_thread.start()
server.serve_forever()
想请问下，为什么在线程里面调用了serve_forever，后面再调用一次这个函数。如果仅仅是为了不让进程结束，为什么不直接server_thread.setDaemon(False)?
同疑惑
根据官方文档的同样用法,并没有server.serve_forever()这一句.
# Start a thread with the server — that thread will then start one
# more thread for each request
server_thread = threading.Thread(target=server.serve_forever)
# Exit the server thread when the main thread terminates
server_thread.setDaemon(True)
server_thread.start()
from:http://docs.python.org/library/socketserver.html
应该改为
server_thread = threading.Thread(target=server.serve_forever())

class MyTCPSocketServerHandler(SocketServer.BaseRequestHandler):
“””
The RequestHandler class for our server.
It is instantiated once per connection to the server, and must
override the handle() method to implement communication to the
client.
“””
def handle(self):
#self.request是处理来自客户端的原始类
self.data = self.request.recv(1024).strip()
print “{0} wrote :”.format(self.client_address[0])
print self.data
#收到数据后，回包
self.request.sendall(self.data.upper())
class ThreadedTCPServer(SocketServer.ThreadingMixIn,SocketServer.TCPServer):
pass
if __name__ == “__main__”:
HOST,PORT = “localhost”,8899
server = ThreadedTCPServer((HOST,PORT),MyTCPSocketServerHandler)
server_thread = threading.Thread(target=server.serve_forever())
server_thread.daemon = True
server_thread.start()
print “Server is loop running in “,server_thread.name
前几天刚开始练习 python,现在遇到验证码问题,网上查了下教程,了解到用python获取验证码还是不少.自己琢磨了整个晚上,用的是开源的打码工具tesseractor,但最后都没成功,不知道是什么问题

Hmm it seems like your blog ate my first comment (it was extremely long)
so I guess I’ll just sum it up what I submitted and say, I’m thoroughly enjoying
your blog. I too am an aspiring blog blogger but I’m still new to everything.
Do you have any points for rookie blog writers?
I’d definitely appreciate it.
Thanks for any other informative web site.
The place else could I get that type of information written in such an ideal way?
I’ve a undertaking that I’m just now running on, and I have been at the look out
for such information.
