rest framework中提供三種分頁：

from rest_framework.pagination import PageNumberPagination, LimitOffsetPagination, CursorPagination

全局配置文件：

REST_FRAMEWORK = {
    ‘PAGE_SIZE‘: 2
}

1. 分頁，看第n頁，每頁顯示n條數據

例如：http://127.0.0.1:8000/api/article/?page=2&size=1

分頁

class MyPageNumber(PageNumberPagination):
    page_size 
 
= 2  # 每頁顯示多少條
    page_size_query_param = ‘size‘  # URL中每頁顯示條數的參數
    page_query_param = ‘page‘  # URL中頁碼的參數
    max_page_size = None  # 最大頁碼數限制

視圖

class ArticleList(APIView):
    def get(self, request, *args, **kwargs):
        res = {"code": 0}
        article_list = models.Article.objects.all().order_by("
 
id")
        # 分頁
        page_obj = MyPageNumber()
        page_article = page_obj.paginate_queryset(queryset=article_list, request=request, view=self)
        ser_obj = ArticleSerializer(page_article, many=True)
        res["data"] = ser_obj.data
        return Response(res)

返回帶頁碼鏈接的響應

class ArticleList(APIView):
    def get(self, request, *args, **kwargs):
        res = {"code": 0}
        article_list = models.Article.objects.all().order_by("id")
        # 分頁
        page_obj = MyPageNumber()
        page_article = page_obj.paginate_queryset(queryset=article_list, request=request, view=self)
        ser_obj = ArticleSerializer(page_article, many=True)
        res["data"] = ser_obj.data
        return page_obj.get_paginated_response(res)

2. 分頁，在n個位置，向後查看n條數據

例如：http://127.0.0.1:8000/api/article/?offset=2&limit=2

分頁

# offset分頁
class MyLimitOffset(LimitOffsetPagination):
    default_limit = 1
    limit_query_param = ‘limit‘
    offset_query_param = ‘offset‘
    max_limit = 999

class ArticleList(APIView):
    def get(self, request, *args, **kwargs):
        res = {"code": 0}
        article_list = models.Article.objects.all().order_by("id")
        # 分頁
        page_obj = MyLimitOffset()
        page_article = page_obj.paginate_queryset(queryset=article_list, request=request, view=self)
        ser_obj = ArticleSerializer(page_article, many=True)
        res["data"] = ser_obj.data
        return page_obj.get_paginated_response(res)

3.加密分頁,把上一頁和下一頁的id值記住

分頁

# 加密分頁
class MyCursorPagination(CursorPagination):
    cursor_query_param = ‘cursor‘
    page_size = 1
    ordering = ‘-id‘

class ArticleList(APIView):
    def get(self, request, *args, **kwargs):
        res = {"code": 0}
        article_list = models.Article.objects.all().order_by("id")
        # 分頁
        page_obj = MyCursorPagination()
        page_article = page_obj.paginate_queryset(queryset=article_list, request=request, view=self)
        ser_obj = ArticleSerializer(page_article, many=True)
        res["data"] = ser_obj.data
        # return Response(res)
        return page_obj.get_paginated_response(res)
