WARNINGS:
?: (rest_framework.W001) You have specified a default PAGE_SIZE pagination rest_framework setting,without specifying also a DEFAULT_PAGINATION_CLASS.
    HINT: The default for DEFAULT_PAGINATION_CLASS is None. In previous versions this was PageNumberPagination. If you wish to define PAGE_SIZE globally whilst defining pagination_class on a per-view basis you may silence this check.

解决办法:

修改setting配置文件:

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': ('rest_framework.permissions.IsAdminUser', ),
    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',  # 添加这一行解决,
    'PAGE_SIZE': 10 # 默认page_size
}
