@zcjwin, it is described in the documentation that the default value of page_size_query_param is None so that the client may not control the requested page size.

page_size_query_param - If set, this is a string value indicating the name of a query parameter that allows the client to set the page size on a per-request basis. Defaults to None, indicating that the client may not control the requested page size.

ref: Official documentation

But you can set PAGE_SIZE globally in your settings. Example:

REST_FRAMEWORK = {
    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
    'PAGE_SIZE': 100
}

Even you can modify this behavior of PageNumberPagination by creating your own Pagination class which will override PageNumberPagination class. Example:

class MyPageNumberPagination(PageNumberPagination):
    page_size = 100
    page_size_query_param = 'page_size'
    max_page_size = 1000

then use it in your View class like this

class MyView(generics.ListAPIView):
    ...
    pagination_class = MyPageNumberPagination

Even you can use this custom pagination class globally

REST_FRAMEWORK = {
    'DEFAULT_PAGINATION_CLASS': 'apps.core.pagination.MyPageNumberPagination'
}
