Django 记录所有 GET 请求
Django Logging all the GET requests
我正在尝试将出现在控制台中的所有 GET 请求从 django 放入数据库中。例如：
控制台日志：
[23/May/2019 13:58:44] "GET /testapp/ HTTP/1.1" 200 409
[23/May/2019 13:58:45] "GET /testapp/page2/ HTTP/1.1" 200 172
我正在尝试从中获取时间戳、页面 URL 和用户名并将其放入数据库中，因此数据库中的条目看起来像这样：
id user pageURL timeStamp
96 naeem /testapp/ 2019-05-23 09:37:12.640613
97 naeem /testapp/page2/ 2019-05-23 09:37:13.317271
这是我为中间件编写的代码：
from TestApp.models import ActivityLog
class AccessLogs(object):
# One-time config
def __init__(self, get_response):
self.get_response = get_response
def __call__(self, request):
response = self.get_response(request)
# Add the user and page info into DB
try:
ActivityLog(user=request.user, pageURL=request.path).save()
except Exception as e:
print(e)
return response
问题是它给了我想要的结果，但是如果我单击可下载的文件或图像，它却得不到结果。就像我在网站上有一张静态图片，点击下载，比如：
<a href="{% static 'TestApp/media/cat.jpg' %}" download>Click here to open image</a>
因此，如果我单击它，它会在控制台中显示图像已下载，但不会将其放入数据库中。有什么办法可以使这项工作？任何帮助将不胜感激！

一般来说 Django's Middleware 是为了有效的 request/response 管理而创建的。它有自己的阶段（process_request()、process_view()、process_response()）等等。每次请求到达服务器时，都会调用 Middleware （但在提供静态文件时，并不是每次都会发生这种情况）。这是因为缓存行为。 Django 在浏览器缓存中缓存 static/media 文件（使用 Cache-Control header）。当资源被缓存时，下一个请求资源从浏览器缓存中读取并且请求没有到达服务器。 Django 使用 from django.views.static import serve 方法提供 static/media 文件。 （此方法为缓存设置正确的 HTTP headers）。
在您的 urls.py 中添加这些行。这里是最重要的。
from django.conf import settings
from django.conf.urls.static import static
from django.views.static import serve
from django.views.decorators.cache import never_cache
nocache_serve = never_cache(serve) # never_cache is view decorator. we can use here, also. This will set correct HTTP headers to avoid caching behaviour.
urlpatterns = [
#
# your path goes here
#
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT, view=nocache_serve)
settings.py
# I think you already have this configuration in settings.
STATIC_URL = '/static/'
MEDIA_URL = '/media/'
STATICFILES_DIRS = [
os.path.join(BASE_DIR, 'media')
]
现在，您可以记录所有传入请求（但不要忘记，避免 static/media 文件的缓存行为是个坏主意）。
添加此代码后不要忘记清除浏览器缓存并重新启动服务器。
希望对您有所帮助。
