Python 学习笔记（十七）--Django REST Framework之Response

2023-12-31 10:42 由 东山絮柳仔 发表于 #后端开发

1.函数也是对象

一切皆对象，其实函数也是一个对象，具有属性（可以使用dir()查询）。作为对象，它还可以赋值给其它对象名，或者作为参数传递。

2.Response对象体

from rest_framework.response import Response

Response对象

"""
An HttpResponse that allows its data to be rendered into
arbitrary media types.
"""
    def __init__(self, data=None, status=None,
                 template_name=None, headers=None,
                 exception=False, content_type=None):
        """
        Alters the init arguments slightly.
        For example, drop 'template_name', and instead use 'data'.

        Setting 'renderer' and 'media_type' will typically be deferred,
        For example being set automatically by the `APIView`.

参数说明

data属性对应的为要返回的数据, 字典类型．

status:返回的状态吗,默认为200．

template_name:渲染的模板名字(可以自定义模板).

headers:响应头(可以向响应头中添加数据--字典).

content_type:响应的编码格式

例如:

return Response(serializer.data, status=status.HTTP_201_CREATED)

3.常用属性

.data 传给response对象的序列化后,但尚未rendered处理的数据.
.status_code 为响应状态吗.
.content 经过rendered处理后的数据

4.常用状态码

from rest_framework import status
"""
Descriptive HTTP status codes, for code readability.

See RFC 2616 - https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
And RFC 6585 - https://tools.ietf.org/html/rfc6585
