确定请求的内容类型？ [英] Determine the requested content type?

问题描述

我想编写一个Django视图，它根据所要求的内容提供变体内容。例如，对于text / xml，为text / json提供XML，提供JSON等。有没有办法从请求对象中确定？这样做会很棒：

I'd like to write a Django view which serves out variant content based on what's requested. For example, for "text/xml", serve XML, for "text/json", serve JSON, etc. Is there a way to determine this from a request object? Something like this would be awesome:

def process(request):
    if request.type == "text/xml":
        pass
    elif request.type == "text/json":
        pass
    else:
        pass

为此，在 HttpRequest 上有一个属性吗？

Is there a property on HttpRequest for this?

推荐答案

HttpRequest.META ，更具体地说是 HttpRequest.META.get（ 'HTTP_ACCEPT'）—而不是 HttpRequest.META.get（'CONTENT_TYPE'） 如前所述

HttpRequest.META, more specifically HttpRequest.META.get('HTTP_ACCEPT') — and not HttpRequest.META.get('CONTENT_TYPE') as mentioned earlier
