curl发送POST/GET请求
以OpenStack环境为例：
1.生成认证所需要的token
#token=`openstack token issue|awk -F \’|\’ \’NR==5{print $3}\’`
2. 执行curl命令发送POST请求，关闭虚拟机
#curl -g -i -X POST http://10.180.204.40/compute/v2.1/servers/7a4968fb-da98-41ae-9413-1e37fd2c5411/action -H “Accept: application/json” -H “User-Agent: python-novaclient” -H “OpenStack-API-Version: compute 2.41” -H “X-OpenStack-Nova-API-Version: 2.41” -H “X-Auth-Token: $token” -H “Content-Type: application/json” -d \'{“os-stop”: {“shutdown”:”soft”}}\’
发送成功，如下图所示：
3.curl发送GET请求，以获取虚拟机列表为例
#curl -g -i -X GET http://10.180.204.40/compute/v2.1/servers -H “Accept: application/json” -H “User-Agent: python-novaclient” -H “OpenStack-API-Version: compute 2.41” -H “X-OpenStack-Nova-API-Version: 2.41” -H “X-Auth-Token: $token” -H “Content-Type: application/json”
获取成功如下图所示：
可以看到response信息如下：
