Question

我想在Orion上下文代理全局实例上发布一些数据，并且我已经请求Quick start guide引用的令牌。当我第二天继续编码（java客户端）时，我得到了：

Exception in thread "main" com.sun.jersey.api.client.ClientHandlerException: java.net.SocketException: Unexpected end of file from server

所以我申请了一个新令牌并再次工作。

以这种方式生成的令牌有到期时间吗？多少钱？

我有办法获得一个不到期的令牌吗？

根据OpenStack Keystone默认配置，令牌在1小时后过期：

http://docs.openstack.org/juno/config-reference/content/section_keystone.conf.html

# Amount of time a token should remain valid (in seconds).
# (integer value)
#expiration=3600

您可以通过另一个来续订：

http://developer.openstack.org/api-ref/identity/v3/index.html?expanded=#token-authentication-with-unscoped-authorization

POST /v3/auth/tokens HTTP/1.1
Host: test.ttcloud.net:5001
Content-Type: application/json
X-Auth-Token: {{user-token}}
{
 "auth": {
    "identity": {
        "methods": [
            "token"
        ],
        "token": {
            "id": "{{user-token}}"
        }
    }
 }
}
