我一直在网上寻找这个地方，似乎一切都在检查，也媒体图像非常好地显示
所以我有一个django web应用程序，它有一个FileField，你可以上传pdf，现在我试图显示thouse pdf，但他们得到显示错误，如下图所示。

settings.py

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/4.0/howto/static-files/

STATIC_URL = 'static/'
STATIC_ROOT = os.path.join(BASE_DIR,'static')

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR,'media')

# Default primary key field type
# https://docs.djangoproject.com/en/4.0/ref/settings/#default-auto-field

DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'

X_FRAME_OPTIONS = 'SAMEORIGIN'
