python - 如何在金字塔 notfound_view_config 中返回 HTTPMovedPermanently（301 状态）而不是 HTTPFound（302）

Question

在带有参数append_slash=True的金字塔中使用notfound_view_config，我在重定向时得到 302 http 状态，但我想设置自定义 http 状态 - 301。

@notfound_view_config(append_slash=True, renderer="not_found.mako") def notfound(request): return {}

Answer 1

HTTPFound 似乎是硬编码的AppendSlashNotFoundViewFactory，但您可以使用它的代码作为“未找到视图”的灵感：

from pyramid.interfaces import IRoutesMapper
from pyramid.compat import decode_path_info

@notfound_view_config(renderer="not_found.mako")
def notfound(request):
    path = decode_path_info(request.environ['PATH_INFO'] or '/')
    registry = request.registry
    mapper = registry.queryUtility(IRoutesMapper)
    if mapper is not None and not path.endswith('/'):
        slashpath = path + '/'
        for route in mapper.get_routes():
            if route.match(slashpath) is not None:
                qs = request.query_string
                if qs:
                    qs = '?' + qs
                raise HTTPMovedPermanently(location=request.path+'/'+qs)
    return {}

（未经测试，视为伪代码）

我不推荐使用的类的解决方案：

class append_slash_notfound_factory(AppendSlashNotFoundViewFactory): def __call__(self, context, request): result = super(append_slash_notfound_factory, self).__call__(context, request) if isinstance(result, HTTPFound): return HTTPMovedPermanently(result.location) return result
