ser.serve_forever()
sys.exit(0)
运行服务
./thread_http_server.py
curl ，不等待返回，ctrl +C 来模拟客户端断开
[~]$ ctrl+C
此时服务器端输出日志如下：
query: /hello2 thread=<Thread(Thread-1, started 1103210816)>
search041142.sqa.cm4.tbsite.net - - [15/May/2014 15:54:09] "GET /hello2 HTTP/1.1" 200 -

after call do_Get
after wfile.flush()
希望本文所述对大家的Python程序设计有所帮助。
