drf除了在数据序列化部分简写代码以外,还在视图中提供了简写操作。所以在django原有的django.views.View类基础上,drf封装了多个子类出来提供给我们使用。
Django REST framwork 提供的视图的主要作用:
请求与响应
REST framework 传入视图的request对象不再是Django默认的HttpRequest对象,而是REST framework提供的扩展了HttpRequest类的Request类的对象。
REST framework 提供了Parser解析器,在接收到请求后会自动根据Content-Type指明的请求数据类型(如JSON、表单等)将请求数据进行parse解析,解析为类字典[QueryDict]对象保存到Request对象中。
Request对象的数据是自动根据前端发送数据的格式进行解析之后的结果。
包含了解析之后的文件和非文件数据
包含了对POST、PUT、PATCH请求方式解析后的数据
利用了REST framework的parsers解析器,不仅支持表单类型数据,也支持JSON数据
request.query_params与Django标准的 request.GET 相同,只是更换了更正确的名称而已。
REST framework提供了一个响应类Response,使用该类构造响应对象时,响应的具体数据内容会被转换(render渲染)成符合前端需求的类型。
REST framework提供了 Renderer 渲染器,用来根据请求头中的Accept(接收数据类型声明)来自动转换响应数据到对应格式。如果前端请求中未进行Accept声明,则会采用默认方式处理响应数据,我们可以通过配置来修改默认响应格式。
可以在rest_framework.settings查找所有的drf默认配置项
REST_FRAMEWORK = { ‘DEFAULT_RENDERER_CLASSES‘: ( # 默认响应渲染类 ‘rest_framework.renderers.JSONRenderer‘, # json渲染器 ‘rest_framework.renderers.BrowsableAPIRenderer‘, # 浏览API渲染器 ) }
构造方式:
Response(data, status=None, template_name=None, headers=None, content_type=None)
data数据不要是render处理之后的数据,只需传递python的内建类型数据即可,REST framework会使用 renderer 渲染器处理data。
data不能是复杂结构的数据,如Django的模型类对象,对于这样的数据我们可以使用 Serializer 序列化器序列化处理后(转为了Python字典类型)再传递给data参数。
参数说明:
data: 为响应准备的序列化处理后的数据;
status: 状态码,默认200;
template_name: 模板名称,如果使用HTMLRenderer 时需指明;
headers: 用于存放响应头信息的字典;
content_type: 响应数据的Content-Type,通常此参数无需传递,REST framework会根据前端所需类型数据来设置该参数。
REST framework 提供了众多的通用视图基类与扩展类,以简化视图的编写。
Django REST framwork 提供的视图的主要作用:
APIView 与View的不同之处在于:
支持定义的类属性
在APIView中仍以常规的类视图定义方法来实现get() 、post() 或者其他请求方式的方法。

rest_framework.generics
import
GenericAPIView
继承自APIView,主要增加了操作序列化器和数据库查询的方法,作用是为下面Mixin扩展类的执行提供方法支持。通常在使用时,可搭配一个或多个Mixin扩展类。
提供的关于序列化器使用的属性与方法
方法:get_serializer_class(self)
def get_serializer_class(self):
if self.request.user.is_staff:
return FullAccountSerializer
return BasicAccountSerializer
get_serializer(self, args, *kwargs)
返回序列化器对象,主要用来提供给Mixin扩展类使用,如果我们在视图中想要获取序列化器对象,也可以直接调用此方法。
提供的关于数据库查询的属性与方法
属性:queryset 指明使用的数据查询集
get_queryset(self)
返回视图使用的查询集,主要用来提供给Mixin扩展类使用,是列表视图与详情视图获取数据的基础,默认返回queryset属性,可以重写,例如:
def get_queryset(self):
user = self.request.user
return user.accounts.all()
返回详情视图所需的模型类数据对象,主要用来提供给Mixin扩展类使用。
在试图中可以调用该方法获取详情信息的模型类对象。
其他可以设置的属性
url路由
