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
project_id = req.headers.get(X-Auth-Project-Id , admin)# 设置默认的项目 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)# 伪造 token
res.headers[X-Server-Management-Url] = os_url # 设置 url
res.content_type = text/plain # 设置 content-type res.status = 204 return res
token = req.headers[X-Auth-Token]
user_id, _sep, project_id = token.partition(:)
project_id = project_id or user_id

remote_address = req.headers.get(X-Forwarded-For , remote_address)
is_admin = always_admin or (user_id == admin)
