H版Openstack使用noauth方法

一、nova部分
1.修改nova的api-paste.ini文件，找到composite:openstack_compute_api_v2条目：
将

keystone = faultwrap sizelimit authtoken keystonecontext ratelimit osapi_compute_app_v2

修改为

Keystone = faultwrap sizelimit noauth ratelimit osapi_compute_app_v2

2.根据noauth这个filter的指向

[filter:noauth]
paste.filter_factory = nova.api.openstack.auth:NoAuthMiddleware.factory

修改nova.api.openstack.auth:NoAuthMiddleware这个方法:
将base_call函数中

        token = req.headers['X-Auth-Token']
        user_id, _sep, project_id = token.partition(':')
        project_id = project_id or user_id

修改为

        token = req.headers['X-Auth-Token']
        user_id = req.headers.get('X-Auth-User', 'admin')
        project_id = req.headers.get('X-Auth-Project-
