某些需求下，需要通过Django代理后端，比如开发celery定时任务时候，需要代理后端的flower，代理后端可以直接使用Django自带的授权，方便权限控制

具体操作如下

1.安装 django-proxy 包，进行代理

pip install django-proxy

2.编写view，用与代理后端flower

settings.py中添加下面配置

CELERY_FLOWER_PORT = 5566
CELERY_FLOWER_HOST = '127.0.0.1'
CELERY_FLOWER_AUTH = 'flower:flower123.'

 flower.py文件如下

import base64
import logging

from django.conf import settings
from django.http import HttpResponse
from django.utils.translation import gettext as _
from django.views.decorators.clickjacking import xframe_options_exempt
from proxy.views import proxy_view
from rest_framework.views import APIView

logger = logging.getLogger(__name__)

flower_url = f'{settings.CELERY_FLOWER_HOST}:{settings.CELERY_FLOWER_PORT}'


class CeleryFlowerView(APIView):

    @xframe_options_exempt
    def get(self, request, path):
        remote_url = 'http://{}/api/flower/{}'.format(flower_url, path)
        try:
            basic_auth = base64.b64encode(settings.CELERY_FLOWER_AUTH.encode('utf-8')).decode('utf-8')
            response = proxy_view(request, remote_url, {
                'headers': {
                    'Authorization': f"Basic {basic_auth}"
                }
            })
        except Exception as e:
            logger.warning(f"celery flower service unavailable. {e}")
            msg = _("<h3>服务不在线，请联系管理员</h3>")
            response = HttpResponse(msg)
        return response

    @xframe_options_exempt
    def post(self, request, path):
        return self.get(request, path)

添加url路由配置

from django.conf import settings
from django.contrib import admin
from django.urls import path, include, re_path
from django.views.static import serve

from common.celery.flower import CeleryFlowerView

urlpatterns = [
    path('admin/', admin.site.urls),
    re_path(r'api/flower/(?P<path>.*)', CeleryFlowerView.as_view(), name='flower-view'),
    # media路径配置 开发环境可以启动下面配置，正式环境需要让nginx读取资源，无需进行转发
    re_path('^media/(?P<path>.*)$', serve, {'document_root': settings.MEDIA_ROOT}),
]

 

可以看到上面代理使用了额外的认证配置，是因为flower2.0 中部分操作，需要认证才能操作

3.启动flower进程

celery -A server flower -logging=info --url_prefix=/api/flower  --basic-auth=flower:flower123.  --address=127.0.0.1 --port=5566

4.访问

 可以看到，cookie信息已经传递到后台，然后基于token进行认证
