(一) 認證 -> 獲取Token，服務endpoints -> 調用服務API
1. 用戶名、密碼去keystone認證
$ curl -d '{"auth": {"tenantName": "demo", "passwordCredentials": {"username": "demo", "password": "demo"}}}' -H "Content-type: application/json" http://127.0.0.1:35357/v2.0/tokens | python -m json.tool
附：keystone API實驗 http://www.pubyun.com/blog/openstack/openstack-keystone-api-%E5%AE%9E%E9%AA%8Ccurl/
別的blog：http://my.oschina.net/guol/blog/105430
另：PKI token太大，改爲UUID，在/etc/keystone/keystone.conf
[signing]
#Deprecated in favor of provider in the [token] section
#Allowed values are PKI or UUID
#token_format =
token_format =UUID返回：

}3. 調用服務API
curl -s -X GET http://186.100.253.130:9696/v2.0/networks -H"X-Auth-Token:af6debf9e18c4e1e9709bb18b564a7ab"-H "Content-type:application/json" | python
-mjson.tool
(二) 用Curl操作Neutron API
1. API接口信息，URI信息，request攜帶數據，response數據：
http://docs.openstack.org/api/openstack-network/2.0/content/ch_preface.html
API quick start， 用處不大，從與keystone交互到調用nova等服務：http://docs.openstack.org/api/quick-start/content/
2. Curl使用：
|
-H <line> |
自定義頭信息傳遞給服務器 |
|
-i |
輸出時包括protocol頭信息 |
|
-k |
允許不使用證書到SSL站點 |
|
-v |
顯示詳細信息 |
|
-X <command> |
指定命令 GET/PUT等 |
|
-d <data> |
HTTP POST方式傳送數據 |
-D Dump 將HTTP響應頭部到stdout. 使用時 “-D - ”
3. 操作：
# create network
$ curl -s -X POST -d '{"network":{"name":"test-12","admin_state_up":false}}' http://186.100.253.130:9696/v2.0/networks -H "X-Auth-Token:af6debf9e18c4e1e9709bb18b564a7ab" -H "Content-type:application/json" | python -mjson.tool
# list networks
$ curl -s -X GET http://186.100.253.130:9696/v2.0/networks -H "X-Auth-Token:af6debf9e18c4e1e9709bb18b564a7ab" -H "Content-type:application/json" | python -mjson.tool
# show network
# url = http://186.100.253.130:9696/v2.0/networks/{network_id}
$ curl -X GET http://186.100.253.130:9696/v2.0/networks/3c88bce8-3d36-4509-8300-445cfd936841 -H "X-Auth-Token: af6debf9e18c4e1e9709bb18b564a7ab" -H "Content-type: application/json"
# update network
# url = http://186.100.253.130:9696/v2.0/networks/{network_id}
# update case 1
$ curl -X PUT -d '{"network":{"name":"test-11-v"}}' http://186.100.253.130:9696/v2.0/networks/3c88bce8-3d36-4509-8300-445cfd936841 -H "X-Auth-Token: af6debf9e18c4e1e9709bb18b564a7ab" -H "Content-type: application/json" | python -mjson.tool
# for all non-read-only attributes in network resource, you can update them in one update call.
# update case 2
$ curl -v -X PUT -d '{"network":{"admin_state_up":true, "admin_state_up":true}}' http://186.100.253.130:9696/v2.0/networks/ebfa259d-6d84-49ac-a897-ea8995c666d4 -H "X-Auth-Token: af6debf9e18c4e1e9709bb18b564a7ab" -H "Content-type: application/json"
# network resource
{
"network": {
"admin_state_up": false,

"subnets": [],
"tenant_id": "e70c0a66ca274efc9ca32a5d0532c298"
}
}
# delete network
# url = http://186.100.253.130:9696/v2.0/networks/{network_id}
$ curl -v -X DELETE http://186.100.253.130:9696/v2.0/networks/3c88bce8-3d36-4509-8300-445cfd936841 -H "X-Auth-Token: af6debf9e18c4e1e9709bb18b564a7ab" -H "Content-type: application/json"
(附) 好用的REST客戶端：
1. GUI: rest-client
https://code.google.com/p/rest-client/
2. cmd line: curl
