Django站点地图在Heroku上使用双https://生成

Question

我正在使用站点地图框架生成站点地图。Google搜索控制台声明站点地图是无效的文件格式。它似乎是有效的XML，但站点地图中的URL有一个双https://，我不知道为什么

只有在Heroku上托管并且settings.py中允许的主机设置为Heroku域名时，才会发生这种情况。当我在没有允许的主机的情况下在本地运行应用程序时，sitemap会生成完美的结果

这是什么原因造成的，我如何修复它

网站地图：

<URL>
<loc>https://https://swflreliefrealty.herokuapp.com/</loc>
<changefreq>daily</changefreq>
<priority>0.5</priority>
</url>
<URL>
<loc>https://https://swflreliefrealty.herokuapp.com/contact/</loc>
<changefreq>daily</changefreq>
<priority>0.5</priority>
</url>

Djangositemap.py：

from django.contrib.sitemaps import Sitemap
from django.urls import reverse
from blog.models import Post

class StaticViewSitemap(Sitemap):
    changefreq = 'daily'
    priority = '0.5'

    def items(self):
        # Return list of url names for view to include in sitemap
        return ['home', 'contact', 'success', 'blog']

    def location(self, item):
        return reverse(item)

class BlogSitemap(Sitemap):
    changefreq = 'daily'
    priority = '0.5'
    def items(self):
    return Post.objects.all()

Djangosettings.py：

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

Answer 1

我怀疑您的sites.Site模型在生产数据库中的domain设置为https://swflreliefrealty.herokuapp.com。网站框架is used by the sitemap framework

站点的domain{a2}，没有协议，例如swflreliefrealty.herokuapp.com

因为它存储在数据库中，所以很容易在生产（在Heroku上，它不起作用）和开发（在本地，它起作用）中有不同的价值
