1，在设置文件settings.py中配置

python">MEDIA_ROOT = BASE_DIR / 'media/'
MEDIA_URL = '/media/'

2，在根路由文件中加入静态路由（需导入settings和static函数）

python">from django.contrib import admin
from django.urls import path, include
#static函数用于返回服务器文件的路由
from django.conf.urls.static import static
from django.conf import settingsurlpatterns = [path('admin/', admin.site.urls),path('', include('frontend.urls')),path('backend/', include('backend.urls')),path('testing/', include('testing.urls')),
] + static(settings.MEDIA_URL,document_root = settings.MEDIA_ROOT)

3，模板文件中的使用

<img src="{{ MEDIA_URL|add:'testing/books/'|add:item.imageurl}}" alt=""/>

附django的settings.py如下：
