如何进行keystone rest api V3 版本测试

如何进行keystone rest api V3 版本测试，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。

1. 用户认证，默认域的token
   

   curl -i \
     -H "Content-Type: application/json" \
     -d '
   {
       "auth": {
           "identity": {
               "methods": [
                   "password"
               ],
               "password": {
                   "user": {
                       "domain": {"id":"default"},
                       "name": "admin",
                       "password": "openstack"
                   }
               }
           }
       }
   }' \
     http://localhost:5000/v3/auth/tokens ; echo

   保存返回的Header，

   X-Subject-Token: ecfc51857b5747d2b6438f17e5e2fe0c

2. 带上token和project，获取另一个token
   

   curl -i \
     -H "Content-Type: application/json" \
     -d '
   {
     "auth": {
       "identity": {
         "methods": [
           "token"
         ],
         "token": {
           "id": "ecfc51857b5747d2b6438f17e5e2fe0c"
         }
       },
       "scope": {
         "project": {
           "name": "admin",
           "domain": {
             "name": "default"
           }
         }
       }
     }
   }' \
     http://localhost:5000/v3/auth/tokens ; echo

   返回一个在project范围内的token：X-Subject-Token: 76d45acefa7d4b928a5573db3a5ff39e
   body内包含许多endpoint

3. 这时就可以使用token向其他服务发起请求。例如：获取flavors
   

   curl -i   -H "X-Auth-Token: 76d45acefa7d4b928a5573db3a5ff39e"   http://localhost:8774/v2.1/9c2b1ae7eb0d48e2b7ed3b4399ee4d3d/flavors; echo
