django 開發服務器，向靜態文件添加標頭

Question

使用 django 開發服務器 (1.7.4)，我想向它提供的所有靜態文件添加一些標頭。

看起來我可以將自定義視圖傳遞給django.conf.urls.static.static ，如下所示：

if settings.DEBUG:
    from django.conf.urls.static import static
    from common.views.static import serve

    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
    urlpatterns += static(settings.STATIC_URL,
        document_root=settings.STATIC_ROOT, view=serve)

而common.views.static.serve看起來像這樣：

from django.views.static import serve as static_serve

def serve(request, path, document_root=None, show_indexes=False):
    """
    An override to `django.views.static.serve` that will allow us to add our
    own headers for development.

    Like `django.views.static.serve`, this should only ever be used in
    development, and never in production.
    """
    response = static_serve(request, path, document_root=document_root,
        show_indexes=show_indexes)

    response['Access-Control-Allow-Origin'] = '*'
    return response

但是，簡單地在INSTALLED_APPS使用django.contrib.staticfiles會自動添加靜態 url，並且似乎沒有辦法覆蓋它們。 從INSTALLED_APPS刪除django.contrib.staticfiles可以完成這項工作，但是，如果我這樣做，靜態文件模板標簽將不再可用。

如何使用 django 開發服務器覆蓋為靜態文件提供的標頭？

Answer 1

staticfiles應用程序覆蓋核心runserver命令，但允許您禁用靜態文件的自動服務：

python manage.py runserver --nostatic

Answer 2

我發現作者的代碼對我不起作用，我會得到如下錯誤：

[10/Dec/2020 18:08:13] "GET /static/img/foo.svg HTTP/1.1" 404 10482
Not Found: /static/img/foo.svg

如果這有所作為，我正在使用 Django 3。

這就是我所做的：

from django.contrib.staticfiles.views import serve

def custom_serve(request, path, insecure=False, **kwargs):
    """
    Customize the response of serving static files.

    Note:
        This should only ever be used in development, and never in production.
    """
    response = serve(request, path, insecure=True)
    response['Access-Control-Allow-Origin'] = '*'
    # if path.endswith('sw.js'):
    #    response['Service-Worker-Allowed'] = '/'
    return response

urls 部分與問題相同：

from django.conf import settings

if settings.DEBUG:
    # Allow custom static file serving (use with manage.py --nostatic)
    from django.conf.urls.static import static
    from CHANGE.THIS.PATH.views import custom_serve
    urlpatterns += static(
        settings.STATIC_URL, document_root=settings.STATIC_ROOT, view=custom_serve
    )
