    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
    # 每页显示多少条数据
    'PAGE_SIZE': 1000
}

from rest_framework import serializers
from .models import EmployeeUser

# 定义ModelSerializer类
class EmployeeUserSerializer(serializers.ModelSerializer):
    class Meta:
        model = EmployeeUser
        #fields = '__all__'
        fields = ("site",
                "employee_name",
                "plantid",
                "employee_id",

PageNumberPagination()可以替换成PageNumberPaginator(PageNumberPagination)，也可以使用默认的PageNumberPagination()

# page参数失效，默认返回前1000条数值
from rest_framework.pagination import PageNumberPagination
class PageNumberPaginator(PageNumberPagination):
    page_size = 1000  # 每页显示10条数据
    page_size_query_param = 'size'  # 每页显示条数的参数名称
    page_query_param = 'page'   # 页码参数名称,比如page=3&size=10 第三页显示10条
    max_page_size = 10  # 最大页码数量控制

@api_view(['GET'])
def EmployeeUserDef(request,site):
    if request.method == 'GET':
        q = EmployeeUser.objects.all().filter(site=site).order_by('id')
        # 分页查询，需要在settings.py设置REST_FRAMEWORK属性
        #pg = PageNumberPagination()
        pg = PageNumberPaginator()
        p = pg.paginate_queryset(queryset=q, request=request)
        # 将分页后的数据传递MySerializer，生成JSON数据对象
        serializer = EmployeeUserSerializer(instance=p, many=True)
        # 返回对象Response由Django Rest Framework实现
        return Response(serializer.data)
