django 如何通过各种网站的 文件验证

from django.http import HttpResponse

def baidu(request):
    with open("baidu.txt", "r") as f:
        f = f.readline()

    # 或者把验证文件的内容写在变量直接返回
    # f = "91ad9b349b0e810a2727exxxxxxxxxxxx"

    return HttpResponse(f)

from django.conf.urls import url
from blog.views import root, google, baidu

urlpatterns = [
                  url(r'^root.txt', root),
                  url(r'^google4252d1cbfae576e8.html', google),
                  url(r'^baidu-verify-7F2A3DC19B.txt', baidu),
              ]

from django.urls import path
from apps.blog.views import root

urlpatterns = [
              # 网站验证
              path('root.txt', root)
              ]
