频率组件

-频率是什么?节流,访问控制
        
        -内置的访问频率控制类SimpleRateThrottle
        -写一个类,继承SimpleRateThrottle
        -class MyThrottle(SimpleRateThrottle):
            scope='aaa'
            def get_cache_key(self, request, view):
                return self.get_ident(request)
        -在setting中:
            REST_FRAMEWORK = {
                'DEFAULT_THROTTLE_RATES':{
                    'aaa':'10/m'
                }
            }
        
        -使用
            局部使用:
                -在视图类中写
                throttle_classes = [MyThrottle,]
            全局使用:
                -在setting中写
                 'DEFAULT_THROTTLE_CLASSES':['app01.MyAuth.MyThrottle',],
        
                -局部禁用:
                    -在视图类中写
                    throttle_classes = []
                    
                    
    
        错误信息改成中文显示:
            def throttled(self, request, wait):
                class MyThrottled(exceptions.Throttled):
                    default_detail = '傻逼'
                    extra_detail_singular = '还剩 {wait} 秒.'
                    extra_detail_plural = '还剩 {wait} 秒'

                raise MyThrottled(wait)
