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

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。获取方法请参见 获取项目ID

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

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

表3 请求Body参数

参数

是否必选

参数类型

描述

queue_name

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

状态码: 201

表4 响应Body参数

参数

参数类型

描述

queue_id

String

队列ID,用于唯一标识一个队列。

queue_name

String

队列名称,同一租户不允许重复。

最小长度:8

最大长度:128

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

在物联网平台最后修改队列的时间。格式:yyyyMMdd'T'HHmmss'Z',如20151212T121212Z。

请求示例

创建amqp队列,名称为myQueue。

POST https://{endpoint}/v5/iot/{project_id}/amqp-queues

{
  "queue_name" : "myQueue"
}

响应示例

状态码: 201

Created

{
  "queue_id" : "d4922d8a-6c8e-4396-852c-164aefa6638f",
  "queue_name" : "myQueue0",
  "create_time" : "20190303T081011Z",
  "last_modify_time" : "20190303T081011Z"
}
