Question

오리온 컨텍스트 브로커 글로벌 인스턴스에 일부 데이터를 게시하고 토큰을 요청했습니다 (Quick start guide). 내가 (자바 클라이언트) 다음 날 코딩을 계속하면 내가 가지고 :

그래서 나는 새로운 토큰을 요청하고 다시했다.

이렇게 생성 된 토큰에는 만료 시간이 있습니까? 얼마나?

만료되지 않는 토큰을 얻는 방법이 있습니까?

Answer 1

OpenStack은 키스톤 기본 구성에 따르면, 토큰 1 시간 후에 만료 :

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}}" 
     } 
    } 
} 
}
