Whether to support APIView ?

f I use APIView to design API, what should I do

eg :

`url(r'^alipay.pay.unified.order/$', views.AlipayPayUnifiedOrderView.as_view(), name='alipay.pay.unified.order'),
`

```
class AlipayPayUnifiedOrderView(BaseOpenGateWayRequestView):
request_params = ('merchant_code', 'total_amount', 'out_trade_no', 'subject', 'card_code')

def get(self, request, format=None):
"""
"""
return resp_data(pay_api.alipay_pay_unified_order(self.get_request_params(request, self.request_params)))
```

Start with the APIView example in the issue, including the URL entry point and AlipayPayUnifiedOrderView class. Determine what APIView support should cover and how it should be documented; the work is done when the supported behavior and usage are clearly recorded.
