django GET POST
django需要读取客户端get和post请求的值。读取处理方法和异常记录于此。

-
request.GET['sth']如果'sth'不存在,将会触发KeyError异常。
-
request.GET.get('sth')如果'sth'不存在,将会得到None。
POST使用的时候也是一样。
example
def index(request):
count = 0
if request.method == 'GET':
try:
t = time.objects.get(id=1)
count = request.GET['onoff']
t.count = int(count)
t.save()
except KeyError:
t = time.objects.get(id=1)
count = str(t.count)
print 'hello'
return render(request, 'index.html', { 'onoff': count})
return render(request, 'index.html')
