我无法使用Django应用中的静态文件

问题描述

我去过这条路线http://127.0.0.1:8000/static/corefiles/chatbot-data.xlsx，但遇到Page not found (404)错误...

我将它们添加到了URL中：

+ static(settings.STATIC_URL,document_root=settings.STATIC_ROOT)

文件目录为/rootproject/core/static/corefiles/testexel.xlsx

我的settings.py：

STATIC_URL ='/ static /'

STATICFILES_DIRS =（ normpath（join（BASE_DIR，'static'））， normpath（join（BASE_DIR，'upload'）），）

STATIC_ROOT = normpath（join（BASE_DIR，'assets'））

解决方法

要在项目中使用静态文件，如果需要查看指定URL处的文档，则需要在设置中指定媒体URL和媒体根：

 + static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)

还将这些内容添加到网址中
