检查HTTPRequest是否为；“真正的”；或者我们正在Plone中运行headless（单元测试）

我发现Plone的注册工具和密码重置工具有问题

即使未进行HTTPRequest，也会呈现Template mail_password_response.pt。此模板是一个全帧Plone页面，依赖于主模板。main_模板有viewlets，它依赖于真实HTTPRequest对象的存在，即它的实际_URL参数

如何解决这种情况？显然，如果没有浏览器显示结果，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，从而让用户界面响应更糟糕？ZMI manage_xxx hacks

解决这个问题的正确方法是什么？是使RegistrationTool不呈现模板，还是使Viewlet对不完整、测试存根、HTTPRequest对象安全

这是p.a.layout.viewlets.common中需要实际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，它会触发呈现完整的

main_template.pt

，即使没有消费者：

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)
