创建AMQP队列
功能介绍
应用服务器可调用此接口在物联网平台创建一个AMQP队列。每个租户只能创建100个队列,若超过规格,则创建失败,若队列名称与已有的队列名称相同,则创建失败。
调用方法
请参见如何调用API。
URI
POST /v5/iot/{project_id}/amqp-queues
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
project_id |
是 |
String |
参数说明:项目ID。获取方法请参见 获取项目ID 。 |
请求参数
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
X-Auth-Token |
否 |
String |
参数说明:用户Token。通过调用IAM服务 获取IAM用户Token接口获取,接口返回的响应消息头中“X-Subject-Token”就是需要获取的用户Token。简要的获取方法样例请参见 Token认证。 |
Instance-Id |
否 |
String |
参数说明:实例ID。物理多租下各实例的唯一标识,建议携带该参数,在使用专业版时必须携带该参数。您可以在IoTDA管理控制台界面,选择左侧导航栏“总览”页签查看当前实例的ID,具体获取方式请参考查看实例详情 。 |
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
queue_name |
是 |
String |
参数说明:队列名称,同一租户不允许重复。 取值范围:长度不低于8不超过128,只允许字母、数字、下划线(_)、连接符(-)、间隔号(.)、冒号(:)的组合。 最小长度:8 最大长度:128 |
响应参数

---|---|---|
queue_id |
String |

create_time |
String |
在物联网平台创建队列的时间。格式:yyyyMMdd'T'HHmmss'Z',如20151212T121212Z。 |
last_modify_time |
String |
