三、博客主页

配置media用户上传数据：

　　1、在settings中配置：

1 #Django用户上传的文件都叫media文件
2 MEDIA_URL = '/media/'
3 MEDIA_ROOT = os.path.join(BASE_DIR,"media")

　　2、在url中配置：

1 from django.views.static importserve2 from django.conf importsettings3
4 urlpatterns =[5     #media相关路由设置
6     re_path(r'^media/(?P<path>.*)$', serve, {"document_root": settings.MEDIA_ROOT}),7 ]
