简单的python django框架开发例子

在此目录下/home/ubuntu/mysite/mysite创建 views.py 文件内容如下：

from django.http import HttpResponse,Http404
import datetime
import os
def sayhi(request):
    return HttpResponse('Hello World,this is my first Web page'）

def current_time(request):
    ow = datetime.datetime.now()
    html = '<html><body> It is now: %s </body></html>'%now
    return HttpResponse(html)

def cpu(request):
    cpu_status = os.popen('cat /proc/cpuinfo').read()
    html = '<html><body><pre> %s</pre></body>'%cpu_status
    return HttpResponse(html)

def hours_ahead(request,offset):
    try:
        offset = int(offset)
    except ValueError:
        raise Http404()
    dt = datetime.datetime.now() + datetime.timedelta(hours=offset)
    html = '<html><body> In %s hour(s),it will be %s</body></html>'%(offset,dt)
    return HttpResponse(html)

在/home/ubuntu/mysite/mysite下修改urls.py文件：

添加代码：

from mysite.views import sayhi
from mysite.views import current_time
from mysite.views import cpu
from mysite.views import hours_ahead

url(r'^views/$',sayhi),
url(r'^time/$',current_time),
url(r'^cpu/$',cpu),
url(r'^time/plus/(\d+)/$',hours_ahead)

运行命令：pythom manage.py runserver 0.0.0.0:9999
