方式一 常用到GET请求（params）
@url http://example.com/orders?name='shubiao'&color='red'
这种是通过url传参（params），那么应该使用：
from rest_framework.views import APIView
from django.http import JsonResponse
class LoginView(APIView):
ret = {'code': 1000, 'msg': 'GET'}
def get(self, request, *args, **kwargs):
name = request.query_params.dict().name
# name = 'shubiao'
color = request.query_params.dict().color
# color = 'red'
return JsonResponse(ret)
request.query_params拿到的是QueryDict的类型，使用dict()方法转化为dict
注意：此处可以使用dict()方法，但不要盲目使用dict(), 大家不妨试试{username: ['zhangning', 'ermeng'], age: 18}.dict(), 遇到这种的QueryDict的时候，你可能就会特别特别的开心。一定要试试，一定要试试， 一定要试试！只有试了才能记得住！
方式二 常用到POST请求
1. formdata

from rest_framework.views import APIView
from django.http import JsonResponse
class LoginView(APIView):
def post(self, request, *args, **kwargs):
ret = {'code': 1000, 'msg': None}
usernames = request.data.getlist('username')
# usernames = ['zhangning', 'hello'] (list)
color = request.data.get('color')
# color = 'red'
username = request.data.get('username')
# username = 'hello'
return JsonResponse(ret)

request.data拿到的参数是QueryDict的类型，此处只讲获取，QueryDict类包含了很多方法，具体的可以参考：https://www.cnblogs.com/scolia/p/5634591.html
2. application/json

from rest_framework.views import APIView
from django.http import JsonResponse
class LoginView(APIView):
def post(self, request, slug=None, *args, **kwargs):
ret = {'code': 1000, 'msg': None}
username = request.data.get('username')
# username = 'xiaoming'
age= request.data.get('age')
# age = 18 (number)
languages= request.data.get('languages')
# languages = ['js', 'node', 'python'] (list)
return JsonResponse(ret)
request.data 拿到是Dict类型
3. application/x-www-form-urlencoded

from rest_framework.views import APIView
from django.http import JsonResponse
class LoginView(APIView):
def post(self, request, slug=None, *args, **kwargs):
ret = {'code': 1000, 'msg': None}
username = request.data.get('username')
# username = 'lin'
age= request.data.get('age')
# age = 18 (number)
return JsonResponse(ret)
request.data 拿到的也是QueryDict类型，获取方法可以参考https://www.cnblogs.com/scolia/p/5634591.html链接
注意：
此处都是基于继承 rest framework 中APIView的类重新封装的request来获取参数喔！
