如何進(jìn)行NoAuthMiddlewareBase及NoAuthMiddleware解析

這期內(nèi)容當(dāng)中小編將會(huì)給大家?guī)碛嘘P(guān)如何進(jìn)行NoAuthMiddlewareBase及NoAuthMiddleware解析，文章內(nèi)容豐富且以專業(yè)的角度為大家分析和敘述，閱讀完這篇文章希望大家可以有所收獲。

NoAuthMiddlewareBase解析

class NoAuthMiddlewareBase(base_wsgi.Middleware):"""如果請(qǐng)求頭里沒有指定對(duì)應(yīng)的請(qǐng)求令牌，則返回一個(gè)偽造的令牌."""    def base_call(self, req, project_id_in_path, always_admin=True):if 'X-Auth-Token' not in req.headers:
            user_id = req.headers.get('X-Auth-User', 'admin')#設(shè)置默認(rèn)的用戶ID
            project_id = req.headers.get('X-Auth-Project-Id', 'admin')#設(shè)置默認(rèn)的項(xiàng)目IDif project_id_in_path:
                os_url = '/'.join([req.url.rstrip('/'), project_id])else:
                os_url = req.url.rstrip('/')
            res = webob.Response()# NOTE(vish): This is expecting and returning Auth(1.1), whereas            #             keystone uses 2.0 auth.  We should probably allow            #             2.0 auth here as well.            res.headers['X-Auth-Token'] = '%s:%s' % (user_id, project_id)#偽造token

NoAuthMiddleware解析

class NoAuthMiddleware(NoAuthMiddlewareBase):
#繼承父類    
@webob.dec.wsgify(RequestClass=wsgi.Request)def __call__(self, req):
return self.base_call(req, True, always_admin=False)
#調(diào)用父類的具體實(shí)現(xiàn)

上述就是小編為大家分享的如何進(jìn)行NoAuthMiddlewareBase及NoAuthMiddleware解析了，如果剛好有類似的疑惑，不妨參照上述分析進(jìn)行理解。如果想知道更多相關(guān)知識(shí)，歡迎關(guān)注億速云行業(yè)資訊頻道。
