NoAuthMiddlewareBase解析
class NoAuthMiddlewareBase(base_wsgi.Middleware):"""如果请求头里没有指定对应的请求令牌，则返回一个伪造的令牌.""" 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')#设置默认的用户ID

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)#伪造token
res.headers['X-Server-Management-Url'] = os_url #设置url
