我发现了 Plone 的 RegistrationTool 和 PasswordResetTool 的问题
即使没有发出 HTTPRequest，也会呈现模板 mail_password_response.pt。该模板是一个依赖于 main_template 的全帧 Plone 页面。main_template 具有依赖于真实 HTTPRequest 对象的存在的 viewlet，即其 ACTUAL_URL 参数。
如何解决这种情况？显然，如果没有浏览器来显示结果，则不应呈现 mail_password_response.pt。但是如何在深层 Plone 代码中检查 HTTPRequest 是否是“真实的”，这应该屈服于 UI 响应，比如可怕的 ZMI manage_xxx hacks？
解决这个问题的正确方法是什么？是让 RegistrationTool 不呈现模板还是让 viewlet 对不完整的测试存根 HTTPRequest 对象安全？
这是在 palayout.viewlets.common 中需要 ACTUAL_URL 的 viewlets 位
class ContentViewsViewlet(ViewletBase):
@memoize
def prepareObjectTabs(self, default_tab='view', sort_first=['folderContents']):
"""Prepare the object tabs by determining their order and working
out which tab is selected. Used in global_contentviews.pt
"""
context = aq_inner(self.context)
context_url = context.absolute_url()
request_url = self.request['ACTUAL_URL']
request_url_path = request_url[len(context_url):]
if request_url_path.startswith('/'):
request_url_path = request_url_path[1:]
这是 CMFPlone RegistrationTool 中的违规调用，main_template.pt即使没有消费者，它也会触发渲染完整：
security.declarePublic('registeredNotify')
def registeredNotify(self, new_member_id):
""" Wrapper around registeredNotify """
membership = getToolByName(self, 'portal_membership')
utils = getToolByName(self, 'plone_utils')
member = membership.getMemberById(new_member_id)
...
return self.mail_password_response(self, self.REQUEST)
