Django项目请求robots.txt返回404错误的技术求助

访问website.com/robots.txt时始终返回404错误。

config > urls.py #

from django.conf import settings
from django.contrib import admin
from django.urls import path, include, re_path
from django.views.generic import TemplateView
from django.conf.urls.static import static
from config import views
from django.conf.urls import handler404, handler500, handler403, handler400

handler404 = views.handler404
handler500 = views.handler500

urlpatterns = [
    path('admin/', admin.site.urls),
    path('accounts/', include('allauth.urls')),
    path('accounts/', include('django.contrib.auth.urls')),
    path('', include('pages.urls')),
    path('plants/', include('plants.urls')),
    path('robots.txt',TemplateView.as_view(template_name='robots.txt', content_type='text/plain')), 
]

config > views.py #

from django.http import JsonResponse, Http404, HttpResponse
from django.shortcuts import render

def handler404(request, exception=None):
    return render(request, '404.html', status=404)

def handler500(request):
    return render(request, '500.html', status=500)

templates > robots.txt #

User-Agent: *
Disallow: /admin/
Disallow: /accounts/

部分文件夹结构 #

    |---pages
    |   |---about.html

    |---robots.txt

• 将handler404函数的参数从exception=None改为仅exception
• 将robots.txt的视图和URL规则迁移至pages应用，并将robots.txt文件放到pages模板文件夹中
• 移除URL规则中的content_type='text/plain'参数
• 查阅多篇教程仍未找到问题根源
