Orion 上下文代理全局实例令牌

Question

我想在 Orion context broker 全局实例上发布一些数据，并且我已请求 Quick start guide 中提到的令牌。当我第二天继续编码（java 客户端）时，我得到：

Exception in thread "main" com.sun.jersey.api.client.ClientHandlerException: java.net.SocketException: Unexpected end of file from server
at com.sun.jersey.client.urlconnection.URLConnectionClientHandler.handle(URLConnectionClientHandler.java:155)

所以我请求了一个新的令牌并再次工作。

以这种方式生成的令牌有过期时间？多少钱？

我有办法获得不会过期的令牌吗？

Answer 1

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

您可以通过购买另一个来续订：

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}}"
        }
    }
 }
}
