如何传输 url 参数以重新配置自定义谓词检查器

我想创建一个 repoze 自定义谓词检查器，它能够访问 url 参数并验证某些内容。但我想使用allow_only 在所有控制器的范围内设置此权限检查器。类似于：

class MyController(BaseController):

    allow_only = All(not_anonymous(msg=l_(u'You must be logged on')),
                     my_custom_predicate(msg=l_(u'something wrong')))

    def index(self, **kw):
        return dict()

然后，my_custom_predicate 应该检查每个 MyController 方法中每个请求的 url 参数，并执行它所做的任何操作。问题在于：如何允许 my_custom_predicate 检查 url 参数，以我上面写的方式使用它。

原文

I would like to create a repoze custom predicate checker that is capable to access url parameters and validate something. But I would like to use allow_only to set this permission checker in all the controller's scope. Something like:

class MyController(BaseController):

    allow_only = All(not_anonymous(msg=l_(u'You must be logged on')),
                     my_custom_predicate(msg=l_(u'something wrong')))

    def index(self, **kw):
        return dict()

then, my_custom_predicate should check the url paramters for every request in every MyController method, and do whatever it do.
The problem is just that: how to allow my_custom_predicate to check the url parameters, using it in that way I wrote above.

可能您需要使用 ControllerProtector

from repoze.what.plugins.pylonshq import ControllerProtector

allow_only = All(not_anonymous(msg=l_(u'You must be logged on')),
                     my_custom_predicate(msg=l_(u'something wrong')))

@ControllerProtector(allow_only)
class MyController(BaseController):

    def index(self, **kw):
        return dict()

请参阅 http 上的文档://code.gustavonarea.net/repoze.what-pylons/API.html

May be you need to use ControllerProtector

allow_only = All(not_anonymous(msg=l_(u'You must be logged on')),
                     my_custom_predicate(msg=l_(u'something wrong')))

@ControllerProtector(allow_only)
class MyController(BaseController):

    def index(self, **kw):
        return dict()
