[英]Proper way to change the default Response content-type
In Pyramid, is there a proper way to change the default Response content-type? 在Pyramid中,是否有一种更改默认Response内容类型的正确方法? I figured out I can do it by using a tween to change the content-type from 'text/html' to 'application/xhtml+xml'.
我发现我可以通过使用补间将内容类型从“text / html”更改为“application / xhtml + xml”来实现。
config.add_tween('app.tweens:XhtmlTween')
class XhtmlTween(object):
def __init__(self, handler, registry):
self.handler = handler
self.registry = registry
def __call__(self, request):
# Process request.
response = self.handler(request)
# Change content-type.
# - Taken from JSON.__call__ from <https://github.com/Pylons/pyramid/blob/master/pyramid/renderers.py>.
if response.content_type == response.default_content_type:
response.content_type = 'application/xhtml+xml'
return response
However, this looks like an awful hack. 然而,这看起来像一个可怕的黑客。 Is there a better way to do this?
有一个更好的方法吗?
From the Pyramid docs, "Request and Response Objects" under Instantiating the Response : 从金字塔文档, 实例化响应下的“请求和响应对象”:
You can subclass
pyramid.response.Response
and setdefault_content_type
to override this behavior.您可以
pyramid.response.Response
并设置default_content_type
以覆盖此行为。
