用 telnet 访问网站发送 HTTP 请求
我们平时对 telnet 用的最多的应该是 telnet 来快速测试服务端口是否可用，其实 telnet 还可以被用来发送 HTTP 请求，是的，没听错，发送 HTTP 请求！
1.首先启动一个 web server：
root@robert-Ubuntu:/media/sf_WorkSpace/HelloNG/src/testcode/djangoTest/robappdj# python manage.py runserver 0.0.0.0:8082
------In the manage.py, To test: this sentence will be output how many times------
---robert--BASE_DIR = /media/sf_WorkSpace/HelloNG/src/testcode/djangoTest/robappdj---
