查询资源空间

功能介绍

资源空间对应的是物联网平台原有的应用,在物联网平台的含义与应用一致,只是变更了名称。应用服务器可以调用此接口查询指定资源空间详情。

调用方法

请参见如何调用API

URI

GET /v5/iot/{project_id}/apps/{app_id}

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

参数说明:项目ID

最小长度:0

最大长度:32

app_id

String

参数说明:资源空间ID,唯一标识一个资源空间,由物联网平台在创建资源空间时分配。资源空间对应的是物联网平台原有的应用,在物联网平台的含义与应用一致,只是变更了名称。 取值范围:长度不超过36,只允许字母、数字、下划线(_)、连接符(-)的组合。

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

参数说明:用户Token。通过调用IAM服务获取。

最小长度:0

最大长度:1024000

Instance-Id

String

参数说明:实例ID。物理多租下各实例的唯一标识,一般华为云租户无需携带该参数,仅在物理多租场景下从管理面访问API时需要携带该参数。

最小长度:0

最大长度:36

响应参数

状态码: 200

表3 响应Body参数

参数

参数类型

描述

app_id

String

资源空间ID,唯一标识一个资源空间,由物联网平台在创建资源空间时分配。资源空间对应的是物联网平台原有的应用,在物联网平台的含义与应用一致,只是变更了名称。

最小长度:1

最大长度:64

app_name

String

资源空间名称。

最小长度:1

最大长度:64

create_time

String

资源空间创建时间,格式:yyyyMMdd'T'HHmmss'Z',如20151212T121212Z。

最小长度:1

最大长度:64

default_app

Boolean

是否为默认资源空间

请求示例

查询资源空间详情。

GET https://{endpoint}/v5/iot/{project_id}/apps/{app_id}

响应示例

状态码: 200

OK

{
  "app_id" : "0ab87ceecbfc49acbcc8d5acdef3c68c",
  "app_name" : "testApp",
  "create_time" : "20151212T121212Z",
