3.测试：
Administrator@USER-20150313KE ~
$ curl -XPUT http://127.0.0.1:8000/?message=
{‘Put‘:‘None‘}
$ curl -XPUT http://127.0.0.1:8000/?message=kkk
{‘Put‘:‘kkk‘}
$ curl -XDELETE http://127.0.0.1:8000/?message=kkk
delete: kkk
$ curl -XDELETE http://127.0.0.1:8000/?message=
delete:
#命令行可以识别put和delete方法，网页里确无法识别，仅能post和get,,,郁闷中
5.默认运行端口：8000
也可以设置：python web_run.py --port=8080
